Code P2118 2018 Toyota RAV4 Description

The Electronic Throttle Control System (ETCS) has a dedicated power supply circuit. The voltage (+BM) is monitored and when the voltage is low (less than 4 V), the Engine Control Module (ECM) concludes that the ETCS has a fault and the current to the throttle actuator is cut. When the voltage becomes unstable, the ETCS itself becomes unstable. For this reason, when the voltage is low, the current to the actuator is cut. If repairs are made and the system has returned to normal, turn the ignition switch OFF. The ECM then allows current to flow to the actuator and the actuator can be restarted.
The ECM monitors the battery supply voltage applied to the throttle actuator. When the power supply voltage (+BM) is less than 4 V for 0.8 seconds or more, the ECM interprets this as an open in the power supply circuit (+BM). The ECM illuminates the MIL and stores the Diagnostic Trouble Code (DTC).
