DTC Troubleshooting: P2118 (40)

DTC P2118:  Throttle Actuator Current Range/Performance Problem

1.Disconnect the throttle actuator control module 16P connector.

2.Measure resistance between throttle actuator control module 16P connector terminals No. 1 and No. 8.

 

Is there about 1.0 W or less?


YES - Go to 3.


NO - Substitute a known-good throttle actuator control module, then go to 7 and recheck. If DTC P2118 is not indicated, replace the original throttle actuator control module, then go to 7.


3.Disconnect the throttle body 6P connector.

4.At throttle body side, measure resistance between the throttle body 6P connector terminals No. 5 and No. 6 with the throttle fully closed.

 

Is there about 1.0 W or less?


YES - Go to 5.


NO - Repair short in the wires between the throttle body and throttle actuator control module (motor drive lines), then go to 6.


5.Replace the throttle body.

6.Reconnect the throttle body 6P connector.

7.Reconnect the throttle actuator control module 16P connector.

8.Turn the ignition switch ON (II).

9.Reset the ECM/PCM with the HDS.

10.Do the ECM/PCM idle learn procedure.

11.Turn the ignition switch OFF.

12.Turn the ignition switch ON (II).

13.Slowly press the accelerator pedal to the floor.

14.Check for Temporary DTCs or DTCs with the HDS.

Are any Temporary DTCs or DTCs indicated?


YES - If DTC P2118 is indicated, check for poor connections or loose terminals at the throttle body and the throttle actuator control module, then go to 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.


NO - Troubleshooting is complete.n
