P2135Throttle/Pedal Position Sensor/Switch "A"/"B" Voltage Correlation

Electronic throttle systems use two throttle position sensors that must agree with each other. The computer found that the A and B throttle position signals do not correlate as they should. Because it cannot trust the throttle reading, it often drops engine power for safety.

Ամենատարածված պատճառներն են՝ Faulty throttle position sensor / throttle body assembly, Connector or wiring problem causing one signal to read wrong, Corroded, loose, or backed-out terminals at the throttle body, Reference voltage or ground fault to the sensors, Throttle plate binding affecting sensor agreement։

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

This commonly forces limp mode with sharply reduced power, so drive cautiously and get prompt diagnosis. A technician should compare both sensor signals and inspect the connector and wiring at the throttle body. Repair faulty wiring/connectors or replace the throttle body, then perform any required relearn.
