KNOCK SENSOR (KS) INSPECTION [L8, LF, L3]

id0140a5802800

  Note

  • Perform the following test only when directed.

## Resistance Inspection

1. Turn the ignition switch to LOCK.

2. Disconnect the KS connector.

3. Measure the resistance between the KS terminals A and B using an ohmmeter.

  • If not as specified, replace the KS.
  • If the KS is okay, but PID value is out of specification, perform the "Circuit Open/Short Inspection".

Specification

  Approx. 4.87 megohms

## Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [L8, LF, L3].)

2. Inspect the following wiring harnesses for open or short. (Continuity check)

### Open circuit

  • If there is no continuity, the circuit is open. Repair or replace the harness.
  - KS terminal A and PCM terminal 2U
  - KS terminal B and PCM terminal 2V

### Short circuit

  • If there is continuity, the circuit is shorted. Repair or replace the harness.
  - KS terminal A and power supply
  - KS terminal A and body GND
  - KS terminal B and power supply
  - KS terminal B and body GND
