What does code P2138 mean?
Throttle/Pedal Position Sensor D/E Voltage Correlation. The Motore computer noticed a disagreement between the two sensors that track how far you are pressing the accelerator pedal. Because they don't match, the computer doesn't know for sure what you want a do and Limiti engine Potenza for safety.
Can I keep driving with code P2138 Attivo?
With caution: limp mode possible, have it checked soon
Common causes — P2138
Faulty accelerator pedal position sensor assembly Poor electrical connection oppure corrosion in the pedal wiring harness Internal failure inside the Motore control module
How do you fix code P2138?
Have a technician check the wiring plug alle the accelerator pedal and test the sensor signals with a diagnostic tool. Since this directly affects Veicolo control and responsiveness, you should have it checked promptly.
