Code P0122 2016 Honda CR-V Description

The P0122 diagnostic trouble code (DTC) for a 2016 Honda CR-V indicates an issue with the Throttle Position Sensor (TPS) 'A' Circuit registering low voltage. The TPS is a crucial component of the vehicle's electronic throttle control system, responsible for monitoring the position of the throttle pedal and sending this information to the engine control module (ECM). The ECM uses this data to determine the appropriate fuel delivery and ignition timing for optimal engine performance.
