Code P0122 2019 Honda CR-V Description

The electronic throttle control system controls the throttle valve opening. The system includes the throttle actuator, the throttle valve, Throttle Position (TP) sensors 'A' and 'B', the Electronic Throttle Control System (ETCS) control relay, the Accelerator Pedal Position (APP) sensor, and the Powertrain Control Module (PCM). TP Sensor 'A' is a semiconductor type, and it is attached to the throttle body and shaft to determine the throttle valve position. The throttle valve position signal from TP Sensor 'A' is transmitted to the PCM for target position feedback control. If the signal from TP Sensor 'A' is a fixed value for a set time, the PCM detects a TP Sensor 'A' malfunction and stores a Diagnostic Trouble Code (DTC).
