Order of inspection
P2139 Throttle/Pedal Position Sensor/Switch D/F Voltage Correlation High
The P2139 code means the signals from position sensors D and F do not match each other. The computer cannot tell which one is correct, so it limits power for safety. Worn sensor tracks, a corroded connector or a shared ground with resistance are the usual causes.
