DTC P2100 | Throttle actuator circuit open
--- | ---
DETECTION CONDITION | • PCM monitors the electronic throttle valve motor current. If the PCM detects that the electronic throttle valve motor current is below the threshold current, the PCM determines that the electronic throttle valve motor 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 | • Throttle valve motor malfunction • Open circuit between throttle body terminal F and PCM terminal 4Y • Open circuit between throttle body terminal E and PCM terminal 4AB • Poor connection of throttle body connector or PCM connector • 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 | CLASSIFY INTERMITTENT CONCERN OR CONTINUOUS CONCERN • Clear the DTC using the WDS or equivalent. • Start the engine and let it idle. • Is the same PENDING CODE present? | Yes | Go to the next step.
No | Go to INTERMITTENT CONCERNS TROUBLESHOOTING procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING [L3 Turbo].)
4 | INSPECT THROTTLE BODY CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to off. • Disconnect the throttle body connector. • Check for poor connection (such as damaged, pulled out terminals, corrosion). • Is there any malfunction? | Yes | Repair or replace the terminal, then go to Step 13.
No | Go to the next step.
5 | INSPECT THROTTLE VALVE ELECTRICAL MALFUNCTION • Measure resistance between throttle body terminal E and F (part-side). • Is resistance approx. 1.3 ohms? | Yes | Go to the next step.
No | Replace the throttle body, then go to Step 13.
6 | CLASSIFY MALFUNCTION ET POWER SUPPLY CIRCUIT OR CONTROL CIRCUIT • Turn ignition switch to the ON position (Engine off). • Measure the voltage between throttle body terminal F (harness-side) and body ground. • Is the voltage B+? | Yes | Malfunction at control circuit. Go to the next step.
No | Malfunction at power supply circuit. Go to the next step.
7 | INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to off. • Disconnect the PCM connector. • Check for poor connection (such as damaged, pulled out terminals, corrosion). • Is there any malfunction? | Yes | Repair terminal, then go to Step 13.
No | Go to the next step.
8 | INSPECT POWER CIRCUIT FOR SHORT TO GROUND • Turn the ignition switch to off. • Check for continuity between throttle body terminal F (harness-side) and body ground. • Is there continuity? | Yes | Repair or replace the wiring harness to a short to ground, then go to Step 13.
No | Go to the next step.
9 | INSPECT POWER CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch to off. • Check for continuity between throttle body terminal F (harness-side) and PCM terminal 4Y (harness-side). • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness for an open circuit, then go to Step 13.
10 | INSPECT CONTROL CIRCUIT FOR SHORT TO POWER SUPPLY • 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 13.
No | Go to the next step.
11 | INSPECT CONTROL CIRCUIT FOR SHORT TO GROUND • Turn the ignition switch to off. • Check for continuity between throttle body terminal E (harness-side) and body ground. • Is there continuity? | Yes | Repair or replace the wiring harness for a short to ground, then go to Step 13.
No | Go to the next step.
12 | INSPECT CONTROL CIRCUIT MALFUNCTION FOR OPEN CIRCUIT • Check for continuity between throttle body terminal E (harness-side) and PCM terminal 4AB (harness-side). • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness for an open circuit, then go to the next step.
13 | VERIFY TROUBLESHOOTING OF DTC P2100 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 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.
14 | 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.
