MANUAL TRANSMISSION APPS REPAIR HARNESS ('03-'04)

Here is niche product for a niche marketplace: 2003-2004 Turbo Diesel owners with a manual transmission where the Accelerator Pedal Position Sensor (APPS) is located under the battery tray. You'll have to remove the drivers side inner fender well to access it.

If your truck is this vintage of vehicle and you are having the infamous "dead pedal" problem, the answer is often to replace the Mopar #53032456AE part. Yet, because of the location under the battery tray, the problem can also be traced to a bad wiring harness (yep, corrosion).Well known replacement TPS vendor Tim Brenneman (Timbo) has developed a replacement harness that goes from the APPS to the ECM main plug.

Now the question: How do you know if you need the 53032456AE APPS or the wiring harness?
