DTC P2103 [L8, LF, L3]

id0102a1811300

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). • The MIL illuminates if the PCM detects the above malfunction conditions during the first drive cycle. • PENDING CODE is available if the PCM detects the above malfunction condition. • FREEZE FRAME DATA is available. • Are any DTCs is stored in the PCM memory.
POSSIBLE CAUSE | • Short to power circuit between throttle body terminal E and PCM terminal 2B • Short to power circuit between throttle body terminal F and PCM terminal 2A • 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 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 off. • Disconnect the throttle body and PCM connectors. • Turn the ignition switch to the ON position (Engine off). • Measure the voltage between the following terminals and body ground: - Throttle body terminal E (wiring harness-side) - Throttle body terminal F (wiring harness-side) • Is the voltage B+? | Yes | Repair or replace the wiring harness for short circuit to power supply, then go to Step 5.
No | Go to the next step.
4 | INSPECT THROTTLE ACTUATOR • Inspect the throttle actuator. • 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 the 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 [L8, LF, L3].)
No | Go to the next step.
6 | VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [L8, LF, L3].) • Is any DTC present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [L8, LF, L3].)
No | Troubleshooting completed.
