NOTE:  Since there is no direct method to test the component itself, troubleshooting is performed on the related components.

Test Procedure 

Unit output voltage inspection

• Preparation
  • Knock sensor 2 (Bank 2) connector (2P): disconnected

• Procedure
  • Jump the knock sensor 2 (Bank 2) connector (2P) terminals No. 1 and No. 2 with a jumper wire.
  • Turn the vehicle to the ON mode.
  • Confirm the HDS [Knock Sensor (Circuit Diag)-B2].

• Normal Conditions
  • HDS [Knock Sensor (Circuit Diag)-B2] value is about 0 V  .

Results 

• If it is normal, there is a problem with knock sensor 2 (Bank 2).
• If it is abnormal, there is a problem with other related components.
