DTC P0115: Inspection

ECT Sensor 1 Inspection 

Test Procedure (Step 1) 

• Preparation
  1. -

     ECT sensor 1 connector (2P): disconnected

• Procedure
  • Turn the vehicle to the ON mode.
  • Confirm the HDS [ECT Sensor 1 Voltage].

• Normal Conditions
  1. -

     HDS [ECT Sensor 1 Voltage] value is more than 0.14 V  .

Test Procedure (Step 2) 

• Preparation
  1. -

     ECT sensor 1 connector (2P): disconnected

• Procedure
  • Jump the ECT sensor 1 connector (2P) terminals No. 1 and No. 2 with a jumper wire.
  • Turn the vehicle to the ON mode.
  • Confirm the HDS [ECT Sensor 1 Voltage].

• Normal Conditions
  1. -

     HDS [ECT Sensor 1 Voltage] value is less than 4.99 V  .

Results 

• If it is normal, there is a problem with ECT sensor 1.
• If it is abnormal, there is a problem with other related components.

	TW open wire inspection	OFF			There is less than 1 Ohm
	SG2 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.
	TW shorted to ground inspection	OFF			There is more than 1 MOhm

Results 

• If 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.
