DTC P2118 Throttle Actuator Control Motor Current Range / Performance: Fail-Safe

When this DTC, as well as other DTCs relating to electronic throttle control system malfunctions, is set, the ECM enters fail safe mode During fail safe mode, the ECM cuts the current to the throttle actuator off, and the throttle valve is returned to a 7° throttle angle by the return spring The ECM then adjusts the engine output by controlling the fuel injection (intermittent fuel cut) and ignition timing, in accordance with the accelerator pedal opening angle, to allow the vehicle to continue running at a minimal speed If the accelerator pedal is depressed firmly and gently, the vehicle can be driven slowly.

Fail safe mode continues until a pass condition is detected, and the engine switch is then turned off
