DTC P2118 Throttle Actuator Control Motor Current Range / Performance: Description

The ETCS (Electronic Throttle Control System) has a dedicated power supply circuit. The voltage (+BM) is monitored and when it is low (less than 4 V), the ECM (included in the hybrid vehicle control ECU) determines that there is a malfunction in the ETCS and cuts off the current to the throttle actuator. When the voltage becomes unstable, the ETCS itself becomes unstable. For this reason, when the voltage is low, the current to the throttle actuator is cut. If repairs are made and the system returns to normal, turn the power switch off. The ECM then allows the current to flow to the throttle actuator so that normal operation can be restored.

HINT:

This ETCS (Electronic Throttle Control System) does not use a throttle cable.
