FAIL-SAFE

When this DTC or other DTCs relating to Electronic Throttle Control System (ETCS) malfunctions are stored, the ECM enters fail-safe mode. During fail-safe mode, the ECM cuts the current to the throttle actuator, and the throttle valve is returned to a fully closed 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 ignition switch is then turned off.

Otherwise, the engine speed is considered to have decreased slowly. In the freeze frame data, the decrease in engine speed from #3 to #5 is 400 rpm or more. In the freeze frame data, the engine speed at #5 is 120 rpm or less. If the vehicle speed is 30 km/h or less and the difference between Engine Speed and SPD (NT) is 100 rpm or less, inspect the automatic transmission. (Depending on the rate of vehicle deceleration, the engine speed may have decreased due to the A/T lock-up release being late.) *2: When a DTC is stored, feedback compensation increases because the air-fuel ratio is determined to be lean. *3: When a DTC is stored, feedback compensation decreases because the air-fuel ratio is determined to be rich.
