P0122 Throttle Position Sensor Circuit Low Input: Causes, Symptoms, and Repair
P0122 indicates the powertrain control module is receiving a throttle position sensor (TPS) voltage signal that falls below the minimum expected threshold of the sensor’s calibrated operating range. The TPS monitors the throttle plate angle from closed (idle) to fully open (wide open throttle) and sends a proportional voltage signal to the PCM that the […]
