Circuit/System Testing
- Clear the DTCs with the scan tool. Operate the vehicle within the Conditions for Running the DTC or within the conditions that you observed from the Freeze Frame/Failure Records.
- With the ignition ON, use a scan tool to observe the DTCs.
- With the ignition OFF, disconnect the accelerator pedal connector. Ensure that the pedal is at the rest position. Measure for more than 450 ohms from the 5-volt reference terminal of the accelerator pedal assembly to the APP sensor 2 signal terminal of the accelerator pedal assembly.
- If less than 450 ohms, replace the accelerator pedal assembly.
- If the pedal test is normal, replace the ECM.
