  Note

  • Perform the following inspection according to the DATA MONITOR function (indicated by monitor item from here onwards).

## Resistance Inspection

1. Disconnect the negative battery cable.

2. Disconnect the knock sensor connector.

3. Measure the resistance between the terminal and the body ground.

  • If not within the specification, replace the knock sensor.
  • If the monitor item condition/specification (reference) is not within the specification, even though the resistance is within the specification, carry out the "Circuit Open/Short Inspection".

Resistance

  Approx. 560 kilohms

## Circuit Open/Short Inspection

1. Inspect the following wiring harnesses for an open or short circuit. (Continuity check)

### Open circuit

  • If there is no continuity, the circuit is open. Repair or replace the wiring harness.
  - Knock sensor and PCM terminal 2BA

### Short circuit

  • If there is continuity, the circuit is shorted. Repair or replace the wiring harness.
  - Knock sensor and body GND
  - Knock sensor and power supply
