DTC P2118:
 Throttle Actuator Current Range/Performance Problem
NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information.
  1. Turn the ignition switch to ON (II).
  1. Clear the DTC with the HDS.
  1. Slowly press the accelerator pedal to the floor.
  1. Check for Temporary DTCs or DTCs with the HDS.
Is DTC P2118 indicated?
YES -
Go to Step 5 .
NO -
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the throttle body and the ECM/PCM.■
  1. Turn the ignition switch to LOCK (0).
  1. Jump the SCS line with the HDS.
  1. Disconnect the throttle body 6P connector.
  1. Disconnect ECM/PCM connector C (49P).
  1. Check for continuity between ECM/PCM connector terminal C43 and throttle body 6P connector terminal No. 4.
Is there continuity?
YES -
Go to Step 10 .
NO -
Repair open in the wire between the throttle body and the ECM/PCM (C43), then go to Step 14 .
  1. Check for continuity between throttle body 6P connector terminals No. 5 and No. 6.
Is there continuity?
YES -
Repair short in the wires between throttle body 6P connector terminals No. 5 (ETCS− line) and No. 6 (ETCS+ line), then go to Step 14 .
NO -
Go to Step 11 .
  1. Check for continuity between body ground and throttle body 6P connector terminals No. 5 and No. 6 individually.
Is there continuity?
YES -
Repair short in the wire between the throttle body 6P connector and body ground, then go to Step 14 .
NO -
Go to Step 12 .
  1. At the throttle body side, measure the resistance between throttle body 6P connector terminals No. 5 and No. 6 with the throttle fully closed.
Is there about 1.0 Ω or less?
YES -
Go to Step 13 .
NO -
Go to Step 22 .
  1. Reconnect all connectors.
  1. Turn the ignition switch to ON (II).
  1. Reset the ECM/PCM with the HDS.
  1. Turn the ignition switch to LOCK (0).
  1. Turn the ignition switch to ON (II).
  1. Slowly press the accelerator pedal to the floor.
  1. Check for Temporary DTCs or DTCs with the HDS.
Is DTC P2118 indicated?
YES -
Check for poor connections or loose terminals at the throttle body and the ECM/PCM, then go to Step 1 .
NO -
Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.■
  1. Reconnect all connectors.
  1. Turn the ignition switch to LOCK (0).
  1. Turn the ignition switch to ON (II).
  1. Slowly press the accelerator pedal to the floor.
  1. Check for Temporary DTCs or DTCs with the HDS.
Is DTC P2118 indicated?
YES -
Check for poor connections or loose terminals at the throttle body and the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM, then go to Step 24 . If the ECM/PCM was substituted, go to Step 1 .
NO -
If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.■
