Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.

Will your tool allow for watching computer inputs? If so is the PCM seeing the accelerator pressed?

Customer: replied 11 months ago.
Don't have that capability
Expert:  Chris (aka- Moose) replied 11 months ago.

Do you have the diagnostic steps for the codes you have and have you done all those steps?

What else can interrupt the signal from the pedal to the ficm?
Customer: replied 11 months ago.
I'm scratching my head too
Expert:  Chris (aka- Moose) replied 11 months ago.

Here are those steps.

2285 by itself normally means the ICP sensor or its wiring is bad.

0237 by itself is normally a faulty MAP sensor

Now those 2 codes and the APPS concern combined leans more so to a VREF issue. The PCM sends out 5 volts to most sensors and those sensors return a different voltage. We need to do 2 things next. Do the diag for those codes and check the VREF at the APPS. Key on using the diagram below, see if the TAN wire at the APPS has 5 volts.
