Ford Escape / Hybrid :: 2004 V6 - Code P0403 EGR Circuit Fault
Aug 11, 2016
I'm pulling a P0403 EGR circuit fault on a 2004 v6 Escape.
Last night I changed out the EGR solenoid. Cleared the code and drove around for a while, got on the highway and cruised for a few miles and everything seemed fine. Turn the car off and back on and the code showed up again.
My next step will be to check the electrical connection to the solenoid. I don't do a lot of auto repair.
With my multimeter I will check for 12 volts. But from what I understand I can not check ground as the PCM sends ground to the solenoid to activate it. How should I check the electrical connections to the EGR solenoid?

After about 6 months I finally got the alternator replaced in the Tribute. I totally forgot about the CEL that was on for EGR Circuit. I've found a couple of pages ( OBD-II Trouble Code: P0403 Exhaust Gas Recirculation Circuit Malfunction ) that explain how to diagnose the issue but I was wondering if any other route for something that may be more common than another thing.

P0403 code that came up on our 2004 Escape 3.0.
Weekend before last I dropped the oil pan, cleaned it and the pickup screen out, and replaced the gasket (switching to full synthetic has been a double edged sword with the leaks that are popping up...); put in new plugs new upper intake manifold gasket and cleaned the throttle body and manifold out. All vacuum hoses inline with the EGR solenoid have also been replaced since the light went on.
While driving the following day the check engine light (CEL) came on and when checked at pep boys read P0403 (no other codes for low EGR flow, etc.). Now, the EGR solenoid is the newest non-regular maintenance item under that hood because the same code came up a couple of years ago (a new solenoid from pep boys fixed that lickety split) so I wasn't overly concerned that it had popped up again, but a bit frustrated that the solenoid only lasted as long as it did. Also, since the light popped up, I have replaced a couple of vacuum lines with some generic 4mm ID (5/32", I think) rubber vacuum hose, but that just headed off what looked like some potential future problem leaks.
Now, here I am a couple of weeks later having tried 4.5 new solenoids (Amazon sent me one with the wrong wiring harness clip so I couldn't verify that it was connected when it didn't work), and thrown some other "just in case" parts at it (new EGR valve and flow sensor, but these may be returned, but may just end up keeping them on, we'll see how things work out). I'm getting a solid reading from the hot lead on the solenoid harness at idle and during static revving, but I can't seem to get anything on the ground pin.
I've cleaned the connections and the larger pin block going into the top of the firewall to no avail. Should this read as a fluttering ground signal all the time, is it only grounded exactly when it wants the solenoid to open the EGR? What can I do to confirm that it should read grounded so I can know one way or the other whether there is a break in the line? I can't find my multimeter (or just dreamed that I picked one up last year). I'm also curious as to whether or not there's a good way to bench test the solenoid. I don't really get a reaction when I hook it up to 12v directly like I do with a vacuum solenoid from my Saab where there's an audible "click."
Is the wire harness for the solenoid a known weak spot? I've found two potential donors at the local junk yard that I can cut the wires out of to play around with/solder a new one in if that's something that the consensus deems may solve my cause. I also had an ABS light come on not too long after the CEL, but when I reset the CEL the ABS light went away and never came back (it only came on when I hit a big expansion joint on a highway bridge, no braking issues since it's been reset and ABS seems to be fully functional, per gravel road test). I still can't seem to read any ground signal at the solenoid harness at idle or with throttle input. I'd like to fix it, but don't want to start digging into the wires blind.

Check engine light came on and stopped by the local autoparts store to get the error code.
Code: P2270
Bank1 Sensor2 fault
Where is this O2 sensor? I've replaced O2's on other cars I've had and just want to make sure I replace the right one.

Girlfriends 04 escape airbag light is blinking code 37. Read something about it being on passenger side what do I look for? I just got done putting in 2 coils, 2 cats, egr, o2 sensor, intake gaskets upper and lower, PCV, injector orings all due to misfire sure there not connected just added info. Other problems include heated seat switch lights for a second then shuts off, and no cruise control. Need to get light off for inspection by end of month....

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.

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.

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!"

I have have been getting a p0671 fault code every time I start my truck now that its cold. If I clear it and its warm it doesn't retrigger at least until it sits overnight again. Is this likely to be that the Glow Plug needs replacing on the #1 cylinder? Autolite Glow Plug is only $20 or so. Mechanic is recommending changing the bank and the harness but I'd rather just do the one GP myself if possible. I see on here that the valve cover has to come off. Which side is #1 on and do I need any gaskets etc? How big a job is it to remove the valve cover? I'd go and look myself but its cold out ...

Just started the truck after not running for a few weeks and drove around fine. Looked down and suddenly a CEL was indicated. Checked it with my Edge Evolution diagnostic mode and Code P0161 came up 2nd bank downstream heater circuit fault. I've also have an exhaust leak in the right passenger side exhaust manifold for about the last year. I've been waiting to install my newer 03' used engine when time and funds permit.

On a family vacation in our 2013 6.7 pulling a 41ft trailer to the Seattle area from Alberta Canada. Made it to destination yesterday. Woke up this morning started truck and cel on. Bought a code reader at the local napa store and read P206 fault inj 6 open circuit. Any thoughts on driving the truck around with a inj fault? Thought I had read here some where that 6 was the regen cylinder.

I recently picked up a 2005 f250 SD 5.4 4x4... I was having issues with sporadic shifting and wandering shifts while cruising around 100kph, scanned it and came up with p0721 OSS sensor circuit performance fault.
I checked the harness and all looks fine, now I attempted to remove the OSS at the rear of the tranny, got the 8mm bolt out however could not, for the life of me get the sensor out. I tried not to use pliers to twist the sensor or anything for fear of breaking the sensor off and having bits go into the transmission.

I was plowing and when I put it in reverse it felt like it slipped, but then the dash message trans malfunction came up. I checked the codes and I got P0722 output shaft speed sensor.
Code P0720 (oss) sensor circuit fault
Then the truck went into safe mods. Is it just the sensor or is my reverse going out...

Where can I find the key pad code on an 08 escape? I don't have the card in the glove box and I don't want to pay the dealer. It should be printed on the security module box. Where to find it? On my f250 it was under the dash behind radio.

I have a Mazda Tribute 2006 2.3. The O/D light would come on, drove it to a friends to scan the check engine light code, and the car almost made it there and then wouldn't remove in reverse, forward, or anything. Turn it off then start it up still wouldn't, then turned it off let it cool and it worked again for a little while.
The code was P0741, just the one code. Took it to a shop to have further tests, they seemed to think it was the clutch was worn and when the fluid heated it lost friction.
Pulled the transmission and thought why not do a Transmission rebuild? I have never done one but there was an awesome video on youtube of the guy doing it so I figured it couldn't be too hard and was just going to try my first rebuild.
According to the guy in the video you always need all new bushing, and we will get a rebuild kit with new clutch packs and the other stuff that comes with those, and sounds like it's a good idea to replace the torque converter.
The car is only at 85K and it looks like the transmission was rebuilt once before he got it at 80K. Maybe a bad rebuild?
Here are some pictures .....
The Input Sprag bearing was shredded and the bushing looks terrible. Can I just replace the bearing and the bushing? Is there any other damage I should be looking for because of this?
The forward planet you can so some eaten metal on the edge and 2 gears spin super smooth and the other 2 you have to push pretty hard to get them to turn. So new forward planet?
The shell's corners look a little rounded I wasn't sure how much was to much, can you tell from the picture if it looks like too much?

I'm getting a p0452 fault on my 2002 Escape 3.0 V6 2WD. From what I've read, that seems to indicate low FTP signal below .22v. As I understand it, the FTP sensor has 5 v applied, and the output to the ECU goes down as tank static pressure increases. Conversely, I think the voltage back to the ECU goes up as tank static pressure decreases (for the vacuum leak test measurement).
What the approximate voltage is at atmosphere (engine not running, vent valve open, etc)?
I'm guessing the "less than .22v minimum" signal back to the ECU might look more like either the signal wire shorted to the frame somewhere or the signal wire open (maybe corrosion in the connector)....
Also, where the FTP sensor is located on the Escape and how to access it?

It has been running very smooth since I changed the lower intake gaskets, and I just went on a 1500 mile round trip roadtrip. It ran perfect the whole way, getting 22mpg to boot. In the last 50 miles, the CEL came one. The code read P0420 which is the cat converter? I dont want to fork up for a new one, are there any tricks to get this fixed or cleared?
