I have recently acquired the dreaded dead pedal. I had my truck scanned for codes a few hours before, and came up with 2 MAP sensor codes, one being voltage to high, the other voltage too low. The first thing that came into my mind, was the VP44. I cracked the #1 injector line at the head and found fuel shooting out with great velocity. I gather that this eliminates a failed VP44. MY question is, Can a map sensor cause dead peddle?

I had that problem with my 04 work truck, and it was the trottle position sensor assembly, about 500 bucks!

I had this problem with my 02. I figured since my apps was probably bad I couldn't hurt it any more. I adjusted the voltage and reset it and I havent had any more issues since. Sure beats spending 500 bucks on a sensor! :peelout

After installing a XZT+ on Monday I threw a P0237 that afternoon, cleared the code with my scanner.. code came back today, scanner would not clear it and now I have a dead pedal as well.

Replaced my LP in January..

I'm going to check the map sensor connection now.. this does not explain why my OBD scanner could not clear the code???

Try the APPS reset and clear the codes...

If the dead pedal comes back and the codes are present you going to need a APPS sensor. Dodge Dealer Only Part! :thud:

Went out this morning. checked the map sensor where it plugs into the qzilla harness.. it was just hanging in there.. unplugged the XZT+ and just connected it back to the block.. code cleared.. runs like it did before. Problem solved.
