id0102b1840200

DTC P2109

TP sensor minimum stop range/performance problem

DETECTION CONDITION

•  The PCM monitors the minimum TP when the closed TP learning is completed. If the TP is less than 6.03% or more than 18.7%, the PCM determines that there is a TP sensor minimum stop range/performance problem.

Diagnostic support note

•  This is a continuous monitor (CCM).

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

•  FREEZE FRAME DATA (Mode 2/Mode 12) is available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  Throttle valve actuator malfunction

―  Throttle valve malfunction

•  PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE 12) HAS BEEN RECORDED • Has the FREEZE FRAME DATA (Mode 12) been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 12) on the 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	INSPECT THROTTLE VALVE ACTUATOR • Inspect the throttle valve actuator. (See THROTTLE BODY INSPECTION [L8, LF].) • Is there any malfunction?	Yes	Replace the throttle body, then go to the next step. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L8, LF].)
3		No	Go to the next step.
4	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 [L8, LF].) • Start the engine and warm it up completely. • Perform the KOER self test. (See KOEO/KOER SELF TEST [L8, LF].) • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L8, LF].)
4		No	Go to the next step.
5	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [L8, LF].) • Are any DTCs present?	Yes	Go to the applicable DTC troubleshooting. (See DTC TABLE [L8, LF].)
5		No	DTC troubleshooting completed.
