DTC Advanced Diagnostics: P2118: General Description
The diagnosis related to the electric throttle control system is done during the vehicle ON mode and OFF (LOCK) mode. The powertrain control module (PCM) opens and closes the throttle actuator to monitor the performance of the throttle body. If any of the following condition is detected, the PCM detects a malfunction and stores a DTC.
- Throttle actuator output duty failure
The throttle actuator output duty is out of a specified range.
- Throttle actuator power supply failure
The throttle actuator power supply voltage is a specified voltage.
- Electric throttle control driver IC failure
The throttle actuator current is a specified current.
