battery current sensor impala Trouble code fault location probable cause; p0121 : throttle position (tp) sensor a/accelerator pedal position (app) sensor a -range/performance problem. 294g0-1hh0a battery current sensor fits leaf pathfinder quest infiniti.. For a passive wheel speed sensor is between 1,000 and 2,500 ohms. this is a normal range for all passive sensors. the specification for active sensors is between Trouble code fault location probable cause; p0121 : throttle position (tp) sensor a/accelerator pedal position (app) sensor a -range/performance problem. Throttle/pedal pos sensor/switch a / b voltage correlation. what does that mean? this diagnostic trouble code (dtc) is a generic powertrain code. ...
