#6 of 18 APP Sensor by alwaysumthn

Feb 22, 2011 (6:02 pm)

Hello! So, I traded in my beloved VW Rabbit for a larger, more practical car, a 2008 AWD Saturn Vue, in Aug 2010. My check engine light keeps going on and off. I went to AutoZone and they troubleshooted the issue and this is the result: APP sensor 1 and sensor 2 signal voltage fault; Explanation: The ECM has detected the APP sensor signal 1 and 2 do not agree; Probable cause: Poor electrical connection and/or failed APP sensor. Is this something that may be covered under the powertrain warranty? If not, how much is this going to cost me? Is this something I can fix myself (somewhat car savy)? Is it OK that I keep driving the car? And just a note....I hate the power engine down function!!! So, I thought that once the check engine light was on, I would not have to deal with this happening (bc before the power engine down function was only happening when the check engine light initially came on)...now it happens even when the light is on. I can go days with the check engine light off, but it will always come back on! Please help!!!

It's the ECU. You'll have to find a new one and get it reprogrammed with a Saturn mechanic. Hope it helps. I'll let you know if everything is resolved once mine is done.

2001 Ford Taurus check eng light on with a DTC P0402.This happens about every 2.5 years and I replace the Backpressure sensor and that will take care of it. Is this normal on this year? We brought it new and now has 58,000 + miles (wife car) I have had 2 other Taurus a 1996 with over 200,000 miles and a 2003 with 170,000 miles and have never replace that part. Purchase the part at Advance Auto Parts should I get Ford parts?

alwaysumthn,
I would definitely recommend working with a GM dealer. I apologize I do not have pricing information. The dealer will be able to assist you in pricing the cost of the repairs. Please keep me updated on your progress.

#10 of 18 2005 Saturn Vue Stalling by jen131

Sep 21, 2011 (10:51 am)

I seem to be having the same problem with my Vue. It stalls and loses power frequently. Have had it in to the GM dealer 3 times and they keep telling me that there is nothing wrong with it and that "it's not happening for them". They say the only code stored in the computer is a "minor misfire". I now have it at a "mom and pop" garage to see if they can figure it out. It has less than 60,000 miles on it. Has anyone come up with an absolute fix for this problem because I'm into this problem for about $1000 between having to rent a car (while the dealer does nothing) and mechanic/labor fees.
  I am considering trying to get rid of it and buy something new, but how exactly does one sell a car that is a lemon????

We actually did get this figured out after about 5 times in the shop!! They knew it somehow centered around the computer but couldn't figure it out. This is how they explained to me what they did. The computer has a bunch of pins in it, that sort of fit into different slots. Each pin has to have a certain pressure to it. If the pressure is not correct it can misfire and cause the car to stall. They had to take apart every single pin and test the pressure and fix where the pressure was wrong, put it all back together and it worked!!
 
Ours was also around 50,000 miles and now we are at 62,000 and it has given us no problems since. See if you can explain this to the mom and pop garage, or return it to the place where you spent the $1,000 and make them do it, and maybe even try to get them to refund you for all the things they did that didn't work. Good luck!!! This is the most frustrating thing ever!! We had all but given up hope..

#14 of 18 2007 Saturn Vue accelarator module failure.... by leehhiltoniii

Dec 11, 2011 (9:11 pm)

This vehicle which belongs to my spouse has preformed without any faults for the past 66,000 miles BUT it's electronic connection from the computer to the accelerator faulted just after we coasted out of our driveway and though the engine was still functioning the accelerator would not accelerate the engine past 900 rpm...
It's a freezing evening here in Northwest Louisiana and I called ONSTAR for a diagnosis but they simply said the engine computer was displaying code 23 faults and they were unaware what was causing the faults...
They suggested turning the key off and removing it from it's ignition several times and restarting to see if the fault would reset itself but this was to no avail...
After summoning a $85.00 tow to a local repair center I awaited the grim reapers report the next day from the maintenance foreman...
Two days later he finally called and said that other than the battery was totally stoned dead and the computer code was showing a history of a code 23 they could find nothing wrong with the vehicle at this visit...
They simply recharged the battery and sent me a bill for $95.00!
The battery was just replaced last Spring and if this vehicle is starting to EAT batteries I gotta dump it or keep it on charge continually...
Does anyone have any suggestions regarding this issue?
If so I'm a listening...leehhiltoniiibellsouth.net

I can understand your frustration. I wanted to clarify a few things, just for my understanding: what brand of battery did you have installed in your Vue last spring? Do you still have documentation on this? There are, depending on the brand, battery warranties. Also, was this diagnosis done at a GM Dealership? If so, we can follow up on this.
 
Please send us an email with more information at your convenience if we can be of service.
