DTC Troubleshooting: P2127 (3.0L Engine): Inspection

APP Sensor Inspection 

Test Procedure 

Unit output voltage inspection

• Preparation
• • APP sensor 6P connector: disconnected

• Procedure
• • Jump the APP sensor 6P connector terminals No. 1 and No. 3 with a jumper wire.
  • Turn the vehicle to the ON mode.
  • Confirm the HDS [APP Sensor B Voltage].

• Normal Conditions
• • HDS [APP Sensor B Voltage] value is more than 0.12 V 

Results 

• If it is normal, there is a problem with the accelerator pedal module.
• If it is abnormal, there is a problem with other related components.

VCC5, APS2 Circuit Inspection 

NOTICE: 

Before disconnecting the PCM connector, jump the SCS line with the HDS, and wait more than 1 minute.

Test Procedure 

• Preparation
• • APP sensor 6P connector: disconnected
  • PCM connector B (72P): disconnected
• Procedure
• • Perform the inspection according to the following table.

	APS2 open wire inspection	OFF			There is less than 1 Ohm
	VCC5 open wire inspection	OFF			There is less than 1 Ohm
	Refer to the Open/Shorted Wire Inspection Description for the method to inspect the shorted circuit below, then start to inspect according to circumstances.
	APS2 shorted to ground inspection	OFF			Not shorted

Results 

• If it is abnormal, there is a problem in the circuit.

PCM Inspection 

Test Procedure 

• If the other inspection item (s) indicated a normal condition, then it is determined that the remaining PCM is the cause.

Results 

• There is a problem with the PCM.
