DTC P2108:00

Throttle valve actuator control module performance problem

DETECTION CONDITION

• If the PCM detects either of the following conditions, the PCM determines that throttle valve 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 P0122:00 or P0123:00)

― TP sensor No.2 output voltage below 0.20 V or above 4.85 V (DTC P0222:00 or P0223:00)

― PCM internal circuit for TP sensor No.1 input circuit malfunction.

― PCM internal 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 (Mode 2)/Snapshot data is available.

• DTCs are stored in the PCM memory.

POSSIBLE CAUSE

• Throttle body connector or terminals malfunction

• Short to ground in wiring harness between throttle body terminal A and PCM terminal 2AK

• Short to power supply in wiring harness between the following terminals:

― Throttle body terminal A—PCM terminal 2AK

― Throttle body terminal C—PCM terminal 2AL

• Open circuit in wiring harness between the following terminals:

― Throttle body terminal A—PCM terminal 2AK

― Throttle body terminal B—PCM terminal 2AO

― Throttle body terminal D—PCM terminal 2AJ

• TP sensor No.1 malfunction

• TP sensor No.2 malfunction

• PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 2)/snapshot data on repair order, then go to the next step.
2	VERIFY RELATED SERVICE 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.
2		No	Go to the next step.
3	VERIFY RELATED PENDING CODE AND STORED DTCS • Turn the ignition switch off, then to the ON position (engine off). • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [L3 Turbo].) • Is the DTC P0122:00, P0123:00, P0222:00 or P0223:00 also present?	Yes	Go to the applicable DTC inspection. (See DTC P0122:00 [L3 Turbo].) (See DTC P0123:00 [L3 Turbo].) (See DTC P0222:00 [L3 Turbo].) (See DTC P0223:00 [L3 Turbo].)
3		No	Go to the next step.
4	INSPECT THROTTLE BODY CONNECTOR CONDITION • Turn the ignition switch off. • Disconnect the throttle body connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 8.
4		No	Go to the next step.
5	VERIFY INTERMITTENT MALFUNCTION AT TP SENSOR NO.1 CIRCUIT • Perform the “INTERMITTENT CONCERN 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 the malfunctioning part according to the inspection results, then go to Step 8.
5		No	Go to the next step.
6	VERIFY INTERMITTENT MALFUNCTION AT TP SENSOR NO.2 CIRCUIT • Perform the “INTERMITTENT CONCERN 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 the malfunctioning part according to the inspection results, then go to Step 8.
6		No	Go to the next step.
7	INSPECT TP SENSOR • Inspect the TP sensor No.1 and No.2. (See THROTTLE POSITION (TP) SENSOR INSPECTION [L3 Turbo].) • Is there any malfunction?	Yes	Replace the throttle body, then go to the next step. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L3 Turbo].)
7		No	Go to the next step.
8	VERIFY DTC TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [L3 Turbo].) • Perform the KOER self test. (See KOEO/KOER SELF TEST [L3 Turbo].) • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L3 Turbo].)
8		No	Go to the next step.
9	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].)
9		No	DTC troubleshooting completed.
