DTC P2108 | Throttle actuator control module performance problem
--- | ---
DETECTION CONDITION | • If the PCM detects either of the following conditions, the PCM determines that throttle actuator control system has a malfunction. - TP sensor power supply voltage below 4.4 V - TP sensor No.1 output voltage below 0.20 V or above 4.85 V (DTC P0122 or P0123) - TP sensor No.2 output voltage below 0.20 V or above 4.85 V (DTC P0222 or P0223) - PCM internal circuit for TP sensor No.1 input circuit 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 | • TP sensor No.1 malfunction • TP sensor No.2 malfunction • Connector or terminal malfunction • Open circuit between throttle body terminal A and PCM terminal 3M • Short to ground between throttle body terminal A and PCM terminal 3M • Open circuit between throttle body terminal B and PCM terminal 3P • Open circuit between throttle body terminal D and PCM terminal 3Q • Short to the constant voltage supply between throttle body terminal A and PCM terminal 3M • Short to the constant voltage supply between throttle body terminal C and PCM terminal 3J • 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 | VERIFY RELATED PENDING CODE AND STORED DTCS • Turn ignition switch to OFF, then ON (Engine off). • Verify pending and/or stored DTCs using the WDS or equivalent. • Is the DTC P0122, P0123, P0222 or P0223 also present? | Yes | Go to appropriate DTC troubleshooting procedure, then go to Step 7.
No | Go to the next step.
4 | VERIFY INTERMITTENT MALFUNCTION AT TP SENSOR NO.1 CIRCUIT • Perform the INTERMITTENT TROUBLESHOOTING procedure to TP sensor No.1 related harnesses and connectors. (See INTERMITTENT CONCERN TROUBLESHOOTING [L3 Turbo].) • Is there any malfunction? | Yes | Repair or replace malfunctioning part, according to inspection result, the go to Step 7.
No | Go to the next step.
5 | VERIFY INTERMITTENT MALFUNCTION AT TP SENSOR NO.2 CIRCUIT • Perform the INTERMITTENT TROUBLESHOOTING procedure to TP sensor No.2 related harnesses and connectors. (See INTERMITTENT CONCERN TROUBLESHOOTING [L3 Turbo].) • Is there any malfunction | Yes | Repair or replace malfunctioning part, according to inspection result, the go to Step 7.
No | Go to the next step.
6 | INSPECT TP SENSOR • Inspect the TP sensor. • Is the TP sensor normal? | Yes | Go to the next step.
No | Replace the throttle body, then go to nest step.
7 | VERIFY TROUBLESHOOTING OF DTC P2108 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the WDS or equivalent. • Turn ignition switch to the ON position (Engine off). • Is the PENDING CODE for this DTC present? | Yes | Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L3 Turbo].)
No | Go to the next step.
8 | 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.
