P2118 THROTTLE CONTROL MOTOR

DTC Description

INFOID:0000000010986460

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connectors (Throttle control motor circuit is shorted.)
• Electric throttle control actuator (Throttle control motor)

FAIL-SAFE

ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx.
5 degrees) by the return spring.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1.

Turn ignition switch OFF and wait at least 10 seconds.

Turn ignition switch ON.

3.

Turn ignition switch OFF and wait at least 10 seconds.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Turn ignition switch ON and wait at least 2 seconds.

2.

Start engine and let it idle for 5 seconds.

3.

Check DTC.

Is DTC detected?

YES

>> Proceed to 

EC-753, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000010986461

1.

CHECK THROTTLE CONTROL MOTOR OUTPUT SIGNAL CIRCUIT
