Ford - Escape :: 2004 - O2 Sensor Failure Repeatedly
Oct 5, 2011
I have a 2004 Ford Escape that seems to have developed an appetite for one of its O2 sensors, about 1 a month for the past 3 months. Specifically Bank 1 Sensor 2. That is this the downstream sensor for cylinders closest to the firewall. I have replaced the sensor twice and the last sensor just popped the code to let me know it's passed on. The code is P0136 is the code that has popped every time. The live data shows a flat 0.0 off of the sensor.
So before I replace another sensor, what would cause the same sensor to die 3 times in a 3 month time period?

Got this 04 Escape 3.0 FWD for my son's first car. It was his mom's and she drove it for years and parked it when she got another car.
I charged the battery and it is holding a good charge. Car would crank but not start. Fuel pump was not coming on. I pulled it out and applied 12V to the connector terminal and it started running so I put it back in and it worked fine.
Drove it home and cleaned it up, pulled out the bad window regulator, put it in the driveway till the next weekend.
After it sat for 3 days it would not start again. The fuel pump was not coming on. I assumed that the old pump that I revived had died again so I bought a new one and put it in and it ran fine.
Went for inspection but OBD2 was NOT READY so I drove it about 60 miles until it threw 3 codes. P0136, P2270, P2271 (O2 sensor problem).
I parked it again to wait till my next chance to work on it. 3 days later I was going to replace the O2 sensor but when I tried to start it the new fuel pump was not coming on again. (2nd fuel pump to die while sitting in the driveway).
So I figured the new fuel pump was a dud maybe, so I returned it and got another new one and put it in and it worked fine again. So I replaced the O2 sensor. Didn't have time to drive it 60 miles again to READY the OBD2 system for inspection so I parked it for a couple more days.
2 days later I was going to drive it around to make the OBD2 READY for inspection and again the fuel pump does not come on.
3 dead fuel pumps doesn't make sense to me so I have been considering it could be the Fuel Pump Driver Module but have read that's not an issue on the Escape like it is on the trucks. Plus I have been unable to locate where it is on this vehicle.

Wife's 04 Escape threw the PO136 code for bank 1 sensor 2 02 sensor. Replaced it and light is off. Not convinced something else isn't causing it.

I just bought the truck on Monday, the CEL popped up on Tues. It shows code 0136. No other codes. CAT "not ready" on scan tool
A google search proved this is a common topic that for some owners is a repeating and cronic sort of issue. What I've read online is that there is an assortment of things that can cause this O2 sensor to throw this code:
Actual bad O2 sensor
Faulty wiring or connection
Misfire throwing mix off
bad convertor
I don't believe this list covers all the accounts I read but these I have were definitely repeat offenders. My intention is to take to a dealer and let them have first crack at sorting it out. I'm handy enough but I see this as something where an unseen detail can drive ya crazy.

Battery kept dying. Had the battery tested. Bench tested as OK but kept dying. Replaced the battery with a new OEM. In a week, that battery was dying too. Alternator was putting out 13V but would dip down to 11V. Also did a parasitic current draw test. Car is only drawing 20mA at rest. Replaced the alternator with brand new. New alternator putting out 14.4V. Battery keeps dying. Still no parasitic current draw.
I did two things right around the same time I started having the issue. I put in a new head unit. I already had an aftermarket head unit and I simply upgraded. I know this isn't the issue because I ripped the thing out completely, including wiring harness, and I still kept having a problem. The other change I made was going from a MFSW to a 3-spoke. I removed the MFSW relay and switched the pins in the column so that the horn and airbag work properly. I tried the cruise control and it doesn't work. When I try to turn on the cruise control, it blows the horn fuse. Replaced the horn fuse and I just don't use the cruise.
What I'm wondering is if I messed up the CCM when I did the steering wheel swap. I've read that bad CCMs can kill batteries. I'm not having the typical faulty CCM issues. The only issues, besides the battery dying, are that the unlock on the keyfob will stop working at random, and the "door ajar" light on my dash flickers at random.

I have a failure on the evap system of my 2002 Escape, and need the proper testing procedure for this particular purge valve. I was able to fix the purge valve on my 2013 Explorer, with no issue, but the Escape has a different type and I'm not sure I'm testing it properly. I want to verify the purge valve is working properly instead of just throwing parts into it. I know it is likely either the valve or the gas cap, but it could be something other than those two items, so I want to get the simple stuff checked out first.

Subject Vehicle: 2003 Ford Escape Limited AWD V6
Mileage: 165,878
The front brake line hoses blew out (R & L) while driving in the city. The parking brake was ineffective in slowing the vehicle as it was traveling down hill. With no means of slowing, the vehicle was turned into a parking lot in an attempt to get on level ground where it was more controllable and could be stopped more easily. The parking lot was not large enough to slow the vehicle and a choice had to be made to crash into a building or drive off the edge of the parking lot to another lot that was approximately 4 feet lower. The 2nd option was chosen. Once the vehicle had landed with great force, it was directed uphill where it eventually came to a stop and put into park.
Unfortunately, extensive damage was done to the frame and underside of the vehicle including oil pan, exhaust system, engine mounts, radiator support frame and under body engine and transmission mounting points. I was told by the tow truck driver, the Firestone auto center and found in other research that Ford Escapes are known for rubber brake line failures. I have had vehicles much older than this and have never had a rubber brake line dry rot and rupture like these. This seems to be a known issue and should be addressed before more damage is done and more people injured or worse. We were lucky. This could have been much worse. Safety issues like this need to be addressed with an immediate recall.

My truck had to be towed to the shop today. The wife and I were stranded for 2 hours and to say I was upset is a understatement. My truck has 13,800 miles and this type of failure is unacceptable. Is it necessary to carry extra sensors around in order to get your truck off the side of the road? BTW, my truck didn't even make it to the side of the road, we had to push it to a narrow shoulder on a busy side road.

Had CEL light and took truck to dealer and they replaced Bank 1 sensor 4, two days later, CEL again Bank 1 sensor 3.
I've trouble shot many EGT sensors on Airplanes, and we could tell if there was a failure coming if a couple failed by testing the sensors themselves. My Service Manager told me there is no way they can check the others out. That sounds like Bull to me.

I'm at 76K miles and I had another exhaust sensor go bad. This time the check engine light came on and the truck did not shut down. I was prepared this time and had an extra sensor / code reader handy.
It was the last sensor in line and very easy to get to. It took me less than five minutes to complete the job. I did use anti seize, but as easy as it came out it probably wasn't necessary.

I only get random TPS failure messages when I am hauling my cab over camper and towing a horse trailer. Other than Murphy's law which dictates that these type of events only happen at the worst times (fully loaded w/ kids, dogs, horses, steep grades, no shoulder, 110+ temps, etc) I figure that the big metal box is disrupting the TPS signal reception. Not sure where the antenna is for the TPS system. I stop and check pressure/temperature just in case but all is well. My Lance has a sheet metal skin and blocks satellite completely and terrestrial radio somewhat, which I don't use anyway.

I just had both manifold cats replaced and the egr valve which blew a hole thru the side of it and I replaced the hoses and the dpfe sensor due to the dealer said the 2 front cats were plugged this is what happened before cats were fixed the dpfe sensor blowing off and melting then the egr blew a hole in the side on my way to the garage and I also replace the fluid sensor for the master cylinder res because it looked broke and my brakes weren't working right either now that all this was fixed 3 days ago I drove it to the store this am 1/4 of a mile and the dpfe hose blew off again what is going on? ford says I should have the fuel pressure checked?

I bought a used 2011 Ford Escape Ltd. which now has 21000 miles on it. The tire pressure sensor indicated a tire was low (it was), and I filled it. Now I intermittently get a message of "Tire pressure sensor fault." The dealer checked it when they changed the oil but it's still coming on, usually when I'm at high speed. It goes off again by itself. Is it important for me to do something?

The facts: 2009 4x4 V6 Escape with Valve stem mounted TPMS
I am getting a tire pressure sensor malfunction fault. The warning light is on and the error message is displayed on the little screen in the gauge cluster.
What I have tried: First I should say I have replace to defective sensor twice now...
1) I put the escape in tpms train mode by hitting the hazard switch off/on about 6 times.
2) I used the train tool to train all the tires but there is one that is giving me trouble and will not train.
3) I tried deflating the problem tire and inflating it to the specified pressure given on the be pillar of the escape (30 psig)... after inflating it I tried to retain it with no luck.
4) I tried rotating the tires and as I mentioned earlier I have replaces the problem sensor twice. Still can't can't get the problem tire to train.
My thoughts:
1) I don't think this is a module error because I can train the other tires and since I rotated them I know their position is not a factor.
2) its possible that I have got two defective tpms sensors but I think that is unlikely.
3) I have read of another procedure to put the escape in tpms train mode that requires you to turn the ignition on/off, step on the break pedal, tap your head and rub your belly, etc... but I have not tried this method. Is there a difference from this train mode verse hitting the hazard switch on/off about 6 times?
4) Does the train tool only work on previously trained sensors? do I need to register the new TPMS sensor with the TPMS module? I have an OBDII tool that connects to scanXL software on my laptop which included the ford proprietary protocol. I looked for a way to program a tpms sensor (similar to how I did it with my toyota) but couldn't find the option.

I have a 2009 Ford Escape XLT, 4 cyl. and in the summer I had the vehicle in as the speed sensor failed. Since that time I have an ongoing ticking sound (sounds like a diesel vehicle). I had the vehicle into my local dealer and after looking over the vehicle they stated that it was "normal". However, my warranty is up in January 2014 and this sound is horrible. Below is a video of the sound.

Over the weekend my 2008 Escape Hybrid manifest 2 problems the same day.
1. The remote keyless entry button stopped working (thought it was dead battery in key)
2. Got a error message 'Tire Pressure Sensor Fault'
So after suffering with having to actually unlock my car with a key (heehee/see sarcastic grin) and getting irritated by the error message. I asked the internet about my symptoms. Got the standard answers of "bad tire pressure sensor/reprogram" and change the battery in the key. But ONE and only one person (namely Enviroguy ) said what I thought was going on - that these two problems were related. (afterall it is 2 wireless devices in the car.)
Changing the key fob battery had no effect & Both keys were unresponsive. Seeing what Enviroguy said about certain chargers or wireless devices can cause interference in the tire sensor and keyless systems. .... Then I remember that I had been using a new no-name charger for my cell phone when this problem started.
I unplugged that charger.....(it was a cheap generic power point to USB adapter). The Keyless system is working... ! The tire pressure error has vanished.... !
I did not go to the car appointment.... Now let's hope this was in fact the problem! May my 2008 Ford Escape Hybrid "Be Healed!"

Fairly early (maybe 50k miles) my '04 Camry 4cyl began developing a vibration during braking that suggested a warped disk . It got progressively worse until it was very severe. So, even though the pads had plenty of life left, I changed the front rotors and pads at about 80k miles. This cleared up the vibration for a little more that 20k miles, but now at 105k miles on the car the braking vibration has returned. It's not bad yet but I can feel it progressing. Why would a warped disk problem return so soon after replacing both front rotors and pads to cure this very problem?

In the last 24 hours my fuel level sensor is failing intermittently. After filling yesterday the fuel gauge went to zero and the MFD read "---" for any range or fuel calculations. Rebooted the car ( ) and it came back on, then off again. today it seems to be working, but I'm waiting for the other shoe to drop.

I've had this happen twice: I'm stopped at a light (on relatively level ground--only slight incline). My gas engine kicks off. OK, fine. As it should. But then it comes on again, maybe a second or two or maybe three or four later, while I'm still stopped. First time, it did this a few times back and forth, all while stopped, waiting for the light.

Trying to figure out whether to fix or scrap our 2005 Prius with 193,000 miles and a mysterious 12V battery problem. What would you do in my situation?
We've had a recurring problem with the 12V accessory battery: I have replaced it myself three times. The last failure was the most mysterious, because after replacing the 12V battery for the third time, I conducted nearly daily voltage tests using the Prius' "secret" vehicle signal check. Voltage coming off of the 12V was normal, if not high the entire time in all of the Prius's various starting and ready modes. I wired up a solar panel to trickle-charge the 12V battery when we weren't around, and we plugged the 12V in at night to a trickle charger to keep the battery topped up.
Nonetheless the day came a few months after the latest replacement when we had our usual 12V failure symptoms: the time on the clock started resetting, the car didn't turn on on the first press, the Prius computer rebooted, and eventually the car wouldn't start without a jump start. This has been super-frustrating, and googling around, I haven't been impressed by people's reported experiences trying to have the dealer try to resolve such problems. My worry is that a dealer repair person will change the accessory 12V battery without fixing the underlying problem. I would suspect a parasitic draw somewhere, but voltage tests when the car was overnighted without any kind of charging did not suggest a serious voltage draw on the 12V battery.
Other details about the car: our keyless entry hasn't worked for several years (dead batteries in the key fob?) and we open the car manually using the key each time. We stick the fob in the slot each time we want to start it. MPG is comparatively low vs. other Priuses, perhaps 44-45 MPG, and lower when the 12V battery starts to die (37-40). I have had the car serviced (oil, etc.) like clockwork every three months; recently, I've noticed the engine is starting to burn oil a bit (level is reported low on each change).
Most of the driving has been done in the flats and the heat of California's Central Valley, and we've put something like 120,000 miles on it just in the last five years. Besides the fact that the 12V battery keeps dying, the car has been very reliable.
We just inherited a free Prius with just 60,000 miles on it, and I have a 1993 Camry with 150k miles on the chassis and maybe 60k miles on the replacement engine I had dropped into it a few years ago. The Camry just passed California's smog test and seems to be running well. We don't want or need three cars.
Our choice is to try to fix the Prius with 193k miles on it and donate the Camry (which gets about 20 miles to the gallon, the horror...), or keep the Camry and donate the Prius. My instinct is to not drop thousands of dollars into the high-mileage Prius, especially if these issues might be pointing to a dying main battery.

What the heck? I have not heard of an over heated O2 sensor. I know they have an extra wire in them for a heater element but I have two temp codes indicating the failure and a permanent code as well.
I know its under warranty but what a weird failure. Overheating...Guess Ill be making that appointment at service earlier than I expected.
