Code P2127 and P2138 APP Sensor Help


When I start my car it starts in limp mode 60% of the time. Codes being thrown are P2127 and P2138 APP Sensor.

I have replaced the Pedal/sensor assembly already. Cleared codes and the problem has come back within a day.

What should I look at next?

From reading the different forums I have seen that there is a way to test the ECM module/wiring harness. I have the service manual but can not find these procedures in it. Should I start here? If so Can someone point me to the right section in the service manual to start testing?

If I am not thinking correctly here, can you point me in the right direction with my next troubleshooting steps?
