haring164 · #1 08-06-2008, 10:05 AM

i have an 06 dodge cummins with the edge in it. i have 2 dtcs coming up, p2121 and p2127 both related to the apps sensor. i have replaced the sensor and had the dealer reflash the computer. im still having the same codes come up. ive cleared the dtcs and removed the edge chip but im still having the same problems. its causing the throttle to shut off for 3-4 seconds between 40-50 mphs while accelerating. the dealer had no idea what could still be causing it. anyone have any ideas?

Have you tried checking the voltage on the APPS? -

P2121 - Accelerator Pedal Position Sensor Circuit 1 Range/Performance.

P2127 - Accelerator Pedal Position Sensor Circuit 2 Low Input.

Bad APPS, Short in APPS or possibly bad PCM -

If the PCM is causing your problems a reflash will not fix it a new PCM from the dealer is the only thing that will seen this several times at our shop and we always send it out. -
