P0120Throttle/Pedal Position Sensor/Switch "A" Circuit

The computer found a general fault in the throttle position sensor or accelerator pedal position sensor circuit (the 'A' circuit). This sensor tells the computer how far the throttle or pedal is open. A fault here means the computer may not know the driver's throttle demand correctly.

Ամենատարածված պատճառներն են՝ Faulty throttle position sensor (TPS) or pedal position sensor, Damaged wiring, chafing, or poor connector contact in the sensor circuit, Corroded or loose sensor connector, Faulty throttle body (on electronic throttle systems), Reference voltage or ground supply problem։

Սովորաբար անվտանգ է կարճ տարածությունների վրա վարել, սակայն շուտով ստուգել տվեք։

The car may be drivable but can enter limp mode or behave erratically, so drive cautiously and get it diagnosed soon. Have a technician check the sensor signal, wiring, and connectors with a scan tool. On drive-by-wire systems the throttle body or pedal sensor may need replacement.
