Component Inspection
1.CHECK KNOCK SENSOR 1
  1. Turn ignition switch OFF.
  2. Disconnect knock sensor 1 harness connector.
  3. Check resistance between knock sensor 1 terminals as per the following.
    noteIt is necessary to use an ohmmeter which can measure more than 10 MΩ.
Knock sensor 1Resistance
Terminals
12Approx. 532 - 588 kΩ [at 20°C (68°F)]
cautionDo not use any knock sensors that have been dropped or physically damaged. Use only new ones.
Is the inspection result normal?
Replace knock sensor 1. Refer to Exploded View.
