DTC P2108[LF ATX (FN4A-EL), L3 ATX]

id0102b6811500

DTC P2108

Throttle actuator control module performance error

DETECTION CONDITION

•  PCM detects either following conditions, PCM determines that throttle actuator control system has 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 continues monitor (CCM).

•  The MIL illuminates if PCM detects the above malfunction condition during the first drive cycle.

•  FREEZE FRAME DATA is available.

•  DTC is stored in PCM memory.

POSSIBLE CAUSE

•  TP sensor No.1 malfunction

•  TP sensor No.2 malfunction

•  Connector or terminal malfunction

•  PCM malfunction

DTC P2108	Throttle actuator control module performance error
DETECTION CONDITION	• PCM detects either following conditions, PCM determines that throttle actuator control system has 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 continues monitor (CCM). • The MIL illuminates if PCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA is available. • DTC is stored in PCM memory.
POSSIBLE CAUSE	• TP sensor No.1 malfunction • TP sensor No.2 malfunction • Connector or terminal malfunction • PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record FREEZE FRAME 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 ignition switch to OFF, then ON (Engine off). • Verify pending and/or stored DTCs using the M-MDS. • Is the DTC P0122, P0123, P0222 or P0223 also present?	Yes	Go to appropriate DTC troubleshooting procedure, then go to Step 7.
3		No	Go to the next step.
4	VERIFY INTERMITTENT MALFUNCTION AT TP SENSOR NO.1 CIRCUIT • Perform INTERMITTENT TROUBLESHOOTING procedure to TP sensor No.1 related harnesses and connectors. (See INTERMITTENT CONCERN TROUBLESHOOTING[LF, L3].) • Is there any malfunction?	Yes	Repair or replace malfunctioning part, according to inspection result, the go to Step 7.
4		No	Go to the next step.
5	VERIFY INTERMITTENT MALFUNCTION AT TP SENSOR NO.2 CIRCUIT • Perform INTERMITTENT TROUBLESHOOTING procedure to TP sensor No.2 related harnesses and connectors. (See INTERMITTENT CONCERN TROUBLESHOOTING[LF, L3].) • Is there any malfunction	Yes	Repair or replace malfunctioning part, according to inspection result, the go to Step 7.
5		No	Go to the next step.
6	INSPECT TP SENSOR • Inspect TP sensor. • Is TP sensor normal?	Yes	Go to the next step.
6		No	Replace 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 M-MDS. • Turn ignition switch to ON (Engine off). • Is PENDING CODE for this DTC present?	Yes	Replace PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION[LF, L3].)
7		No	Go to the next step.
8	VERIFY AFTER REPAIR PROCEDURE • Perform the “After Repair Procedure”. (See AFTER REPAIR PROCEDURE[LF ATX (FN4A-EL), L3 ATX].) • Is any DTC present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE[LF ATX (FN4A-EL), L3 ATX].)
8		No	Troubleshooting completed.
