P2122Throttle/Pedal Position Sensor/Switch D Circuit Low Input

The computer received a lower-than-expected voltage signal from the 'D' throttle or accelerator pedal position sensor circuit. This sensor tells the computer how far the pedal or throttle is pressed. A low signal here means the computer cannot trust the pedal input, so it often limits power for safety.

Ամենատարածված պատճառներն են՝ Faulty accelerator pedal position sensor (or throttle position sensor), Short to ground or open in the sensor signal wire, Corroded, loose, or damaged connectors, Loss of reference voltage or poor ground to the sensor, Wiring harness damage, ECM fault (less common)։

Խուսափեք վարելուց — այս անսարքությունը կարող է վտանգավոր լինել կամ ավելի մեծ վնաս հասցնել։ Անմիջապես ստուգել տվեք։

Have this diagnosed promptly by a professional, because a faulty pedal/throttle position signal can put the car into reduced-power mode and make acceleration unreliable. Minimize driving until it is fixed, especially in traffic. A technician will test the sensor's voltage, reference, and ground and inspect the wiring and connectors.
