Hi there, thanks for your question.
This code is for the accelerator pedal position sensor. Have you replaced it yet?
Customer: replied 2 years ago.
I replaced the entire accelerator assembly. I can't get the proper light response when attempting an ECU rest. The SES light will not flash.
Expert:  Jake replied 2 years ago.
Thanks, ***** ***** code returned even after replacing the pedal assembly and clearing the code?
Do you have a volt meter?
Customer: replied 2 years ago.
Yes, I do have a volt meter. I used my code scanner to reset the codes. But when I try to reset the ECU using the key on 3 second ignition on, pump pedal 5 times, wait 7 or 10 seconds(I tried both), hold down for 12 seconds or wait for SES light to flash I get no flashing SES light.
Expert:  Jake replied 2 years ago.
Yea, that's because the pedal is not sending the signals is my guess. Check for power to the blue wire at the app sensor with key to ON. should be 5volts
Customer: replied 2 years ago.
I will check that today when I get home from work. Which wire is the ground, black?
Expert:  Jake replied 2 years ago.
I will send for a refund for you. thanks
Customer: replied 2 years ago.
i checked the voltage. It is ONLY .2 volts.
Expert:  Jake replied 2 years ago.
Yea .2 volts is not sufficient . You should have 5volts from the ECM.
Might want to move the harness protector at the ECM and see what the voltage is leaving the ECM.
Let me know if that's something your comfortable with.
