Ford Escape / Hybrid :: 2002 V6 - Low FTP Signal Below 22v - Code P0452
Oct 18, 2014
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?

2002 Ford Escape... My OD light started to come on every once in a while, and would go off once I turned the car off... This being said, as far as I could tell, the tranny was running smooth. Then an engine light popped on and this code and explanation come up... P1744 "Torque Converter Clutch System Stuck in OFF position".
I recently came back from a bit of a trip... and after shutting the car off, it didn't want to restart. Since this time, the car has begun to start, but the engine light remains on with the P1744 coming up...
Research seems to indicate that the problem is with the Torque Converter Solenoid. You Tube videos show that there are two solenoids just under the transmission pan...

I have been getting a CEL P0420 for low cat efficiency bank 1 on my 2002 Ford Escape V6. The truck runs fine otherwise. I have ran two loads of Cataclean and the light keeps coming back a few days after CEL reset so I am pretty sure one of cats is done. I am going to replace with an aftermarket cat. My question is, with this code, do I need to replace the front exhaust manifold cat or the rear manifold cat?

I have a very Big problem with my Ford Escape 2002 I have this problems code: P0305 accuses Cylinder #5 P0306 accuses Cylinder #6.
I already change the gasket i buy the felpro Kit, and i Also replace all the sparks and spark plug boots, I clean the air sensors and i also replace the EGR, i try to switch cables, and all is the same the car start buy when i accelerate it just go off, i don't know what can i do next, somebody told me to change the fuel injector, i take the pressure in both spark holes the number 4 was 150 and the 5 and 6 was 120, No leaks oil. My car is a Ford Escape 2002, XLT 3.0 4x4

The other day my truck stalled out and wouldn't start so I had it towed to the shop, the shop tested the fuel pump but couldn't find anything and it fired up and ran fine for them. It ran fine for a day and now is running extremely rich. The only code it's throwing is P0452 which is for the evap system. I spent awhile searching but couldn't find any answer on it.
I couldn't find any loose connections in the harness or on top of the fuel tank, I had the classic FDPM issues before so I replaced that. I'm beyond frustrated with this hulk seems like once a month it wants to quit working.

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?

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.

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.

I am having some ( Bad Luck ) with my 02 escape I been getting random misfire codes started checking over o2 sensors first, replaced one on bank 1 downstream, I have screenshots to look over along with codes....

I own a 2002 Escape, 4WD 4cly manual trans. A couple of days ago, when I left work I stopped at a stop light. I shifted out of gear while I waited for the light to change like I always do. When I went to shift back into gear, I couldn't. I found that if I turned the key off, with the clutch disengaged, I could shift into gear without a problem, start the car up and drive away.
Since the first time this has happened, it has happened a few more times, always when stopped, once or twice while slowing down to stop (low RPMs). Besides all that, the car shifts fine while driving.

I have a 2002 Ford Escape, 6cyl FWD... 110,000 miles.
About a month ago I started seeing a misfire, which of course usually is a COP issue. I should buy stock in whoever makes those. Anyway, the code according to parts store monkey was cylinder 2 misfire, so I replaced the COP. That made no difference. I also replaced the upper intake gaskets and the PCV valve while I was in there.
So I started monitoring when it would happen, and of course got the actual code rather than taking the word of the monkey at the parts store. The code is P0352 Primary / Secondary circuit malfunction.
So after some research I find it could be the harness, it could be the PCM. The question I have is this misfire seems to only be when the motor is started after it's hot. What I mean is I can drive to work 10 miles, no problem. I can drive to Orlando 100 miles away - no problem as long as I don't stop on the way. The only time the misfire happens is when I start the motor when it's hot. So if I drive 10 miles to the store, then drive home before the motor cools completely I'll be coming home on 5 cylinders. If I wait 2 hours between stop and start I never have a misfire.
Does that jive with a true electrical problem? I'm no expert, but I don't understand why driving for 100 miles is fine, but 10 miles, stop start and 10 more is an electrical problem.

Are there any tricks I need to be aware of, or any maintenance threads on changing the lower intake gaskets on my 2002 3.0 V6 Escape? Still having high idle issues when hot, and have checked everything else. I changed the upper gaskets when I replaced the plugs and COPs some time back.
Anything I need to be aware of, or is this similar to changing the upper manifold gaskets?

I have a 2002 Escape XLT V6 4X4. I searched the issue, but others' symptoms don't seem to be quite the same as what I'm seeing. Over the last few weeks, the battery light has randomly come on and off 3 separate times:
- 1st time, light came on at highway speed for about 30 sec and went out. Didn't come back on. Was during daytime, running DRL's, radio (no amp or subs or anything like that, and heater blower on low speed.
- 2nd time was two weeks later or so. Happened at night with just headlights on at around 55mph (RPMs about 2K or so). Again, stayed on for about 30 sec and went out.
- 3rd time was about a week/week and a half later, yesterday morning. Just running DRL's and radio. Light came on, flickered, came on, and then stayed on for a couple of minutes (all at highway speed). I noticed that if I disengaged the overdrive and got the RPMs up, the light would go out. I ran it out of overdrive for about 2 minutes like that, and the light stayed out. Speed limit dropped to 40mph, and the light came back on (lower RPMs at that speed, didn't run it in low gears). Light stayed on for 30 sec - 1 minute, and then went out on its own and has since stayed off.
I took it to Advance yesterday to have it tested, and the results were that it is charging at 13.9V under no load, and 13.87V under a load. The battery tested good, but the machine said it needed to be charged (it hasn't been acting low...car starts just fine).
I'm driving it to work today to see what it does next, and then getting it tested again on my way home. Has anyone here ever had similar symptoms as above? Does this sound like bad diodes in the alternator?

My wife has a 02 Ford Escape XLS with a I4/manual trans, she has been saying it has been making weird grinding noises for a while but has not been able to replicate it for me to hear. Today it locked in gear and stalled, she can depress the clutch and start it, but can't take off in whatever "gear it thinks it's in" and it'll stall. To quote her.
So odds are the clutch or trans is toast, I'm more of a full size truck guy when it comes to doing work, what to look at? She's getting it towed and I have enough tools to do the job just not a ton of time this second to do the research, When I know more I'll add it.

So my buddy has a 2001 escape. It has a shudder at 1k rpm in park and neutral. It's not nearly as noticeable in drive. I scanned it for codes and there isn't one. Ran a power balance on ids and it's straight. Doesn't miss during the shudder either. Has all new coils and plugs. I cleaned IAC. MAF. Ran sea foam through the engine. And there is Lucas oil conditioner in the oil and Lucan fuel injector cleaner in the gas. It runs amazing other than that shudder. What could it be ?

2002 Escape XLS 2.0L 4-cyl 5MT FWD. Slipping Clutch.
I've read here n there that the Escape clutch is a poor design & others have reported that a clutch repair doesn't solve their shuddering problem. After putting off the job for a while, I'd like to replace the clutch.
Here's a topic from here : Manual Transmission shudder / fill & drain access?

My daughter has a 2002 Escape 4WD with 3.0L engine.
Coming home from school a few weeks ago she experienced engine running rough on the highway when trying to accelerate. We ran the diagnostic on it and it revealed that #2 cyl coil was misfiring.
I've replaced all of the rear bank coils (in hopes that I wouldn't have to remove the intake manifold again anytime soon). I also replaced the connectors and weatherproofed them.
Replaced all the plugs while I had easy access too. This all went pretty smooth with exception of breaking 3 of the 5mm coil bolts off inside the valve cover. I've also replaced the upper and lower intake manifold gaskets.
It runs much better now except now on the highway, at 1800 rpm/55 mph if I try a gradual acceleration I get engine sputtering and it won't accelerate. If I push hard on the pedal it will downshift and accelerate normally right past this trouble spot. Other than this it idles and runs great.
I've noticed that the 3/4 in. vac hose on back of manifold is getting pinched closed about 70%. this is the hose that leads down to the top of engine just below lower manifold. I suspect this is the problem but cannot determine the root cause. I assumed it was the intake manifold gaskets but those are now replaced.

I was having problems with my 02 Escape of misfire on cylinders. After doing a lot of checking, changing spark plugs, changing coils, ect, I decided that it could be the computer. So, I ordered one and put it in. When I turned on the key, all the gauges pegged and then came back to zero, but it acted like someone cut the power line to the starter. No click, no nothing. I checked fuses and they are fine. Even changed them around to make sure. Is there something that I have to do when you change the computer to get it to start? Had no problems with the starter prior, so it has to be something associated with the computer and changing it.
