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.
No
Go to the next step.
6
VERIFY AFTER REPAIR PROCEDURE
• Perform the "AFTER REPAIR PROCEDURE".
• Is any DTC present?
Yes
Go to the applicable DTC inspection.
No
Troubleshooting completed.
