The code: P2127- Accelerator Pedal Position (APP) Sensor 2 Circuit Low Voltage
When the ECM detects that the APP sensor 2 voltage is less than 0.16 volt it will trigger that code.
There is a good change the issue is wiring related.
I have attached the trouble shooting steps for the code P2127 below.
Please go thru the steps as it can help you determine the issue.
Let me know of any questions.
