DTC P2103 | Throttle actuator circuit high input
--- | ---
DETECTION CONDITION | • PCM monitors the throttle actuator circuit current. If the PCM detects that the throttle actuator circuit current is excessively high, the PCM determines that the electronic throttle actuator circuit has a malfunction. Diagnostic support note • This is a continuous monitor (CCM). • MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA is available. • DTCs are stored in PCM memory.
POSSIBLE CAUSE | • Short to the power supply between throttle body terminal E and PCM terminal 4AB • Throttle valve motor malfunction • PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded? | Yes | Go to the next step.
No | Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available? | Yes | Perform repair or diagnosis according to the available Service information. If the vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | INSPECT CONTROL CIRCUIT OF THROTTLE ACTUATOR FOR SHORT TO POWER SUPPLY • Turn the ignition switch to off. • Disconnect the throttle body and PCM connectors. • Turn ignition switch to the ON position (Engine off). • Measure the voltage between throttle body terminal E (harness-side) and body ground. • Is the voltage B+? | Yes | Repair or replace the wiring harness for a short to power supply, then go to Step 5.
No | Go to the next step.
4 | INSPECT THROTTLE ACTUATOR • Inspect the throttle actuator. (See THROTTLE ACTUATOR INSPECTION [L3 Turbo].) • Is it normal? | Yes | Go to the next step.
No | Replace the throttle body, then go to the next step.
5 | VERIFY TROUBLESHOOTING OF DTC P2103 COMPLETED • Make sure to reconnect all disconnected connectors. • Turn ignition switch to the ON position (Engine off). • Clear the DTC from the PCM memory using the WDS or equivalent. • Start the engine and warm it up completely. • Is the same DTC present? | Yes | Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L3 Turbo].)
No | Go to the next step.
6 | VERIFY AFTER REPAIR PROCEDURE • Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE [L3 Turbo].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [L3 Turbo].)
No | Troubleshooting completed.
