I have never done it but I know of a very reliable shop. They are a bit pricey but do excellent work and used to work for Cummins for many years. Called "The Diesel Connection" in Joppa Maryland. Just north of 695 off of Mountain Road and Pulaski Highway. They told me about 50% of their work is high performance stuff.

What is the best price and from who?

Here's the P0122:



P0122 (M) Accelerator Position Sensor (APPS)

Signal Voltage Too Low

APPS voltage input below the minimum acceptable

voltage.





Usually NOT related to the VP-44...

Tom, Try reseting the APPS... Disconnect both batteries, turn on the Ignition switch (Yes, with batteries disconnected :>), and maybe turn on the headlights, too. Wait 4 hours or so. The Main thing here is to discharge the capacitor in the PCM that keeps the APPS Data "hot". After the 4 Hours, Turn every switch to "Off", then hook up the Batteries. Next Ignition "on", without starting the engine, then slowly press the accelerator to the floor, and slowly release it. That should reset the APPS.



I am not sure how long the codes will stay, but I think it's 20 start cycles

I agree, a p0122 is usually an APPS on its way out. You can re-calibrate it just like Moose00 said. Also, I would unhook the wireharness connector on the bottom of the apps and at the ECM, clean them with good electronics cleaner, air dry, pack with di-electric grease, and reassemble. Then peform the recalibration. This should make the p0122 go away (at least for a little while).
