DTC P2126[ZJ, ZY, Z6]

id0102c1840400

With Throttle Valve Actuator Only

DTC P2126

Accelerator pedal position (APP) sensor No.2 circuit range/performance problem

DETECTION CONDITION

•  The PCM monitors the APP sensor duty signal. If the input signal (duty signal) is too high or too low than the set value, or the input signal intervals are too short or too long, the PCM determines that the APP sensor No.2 has a malfunction.

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.

•  PENDING CODE is available if the PCM detects the above malfunction condition.

•  FREEZE FRAME DATA is available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  APP sensor No.2 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 the FREEZE FRAME DATA 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 APP SENSOR NO.2 • Inspect the APP sensor No.2. (See ACCELERATOR PEDAL POSITION (APP) SENSOR INSPECTION[ZJ, ZY, Z6].) • Is there any malfunction?	Yes	Replace the accelerator pedal, then go to Step 4. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION[ZJ, ZY, Z6]..)
3		No	Go to the next step.
4	VERIFY TROUBLESHOOTING OF DTC P2126 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. • Start the engine. • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION[ZJ, ZY, Z6].)
4		No	Go to the next step.
5	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE[ZJ, ZY, Z6].) • Is any DTC present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE[ZJ, ZY, Z6].)
5		No	DTC troubleshooting completed.
