Component Inspection

1. Turn ignition switch OFF.
2. Disconnect knock sensor 1 harness connector.
3. Check resistance between knock sensor 1 terminals as per the following.
   NOTE: It is necessary to use an ohmmeter which can measure more than 10 MΩ.

   Knock sensor 1		Resistance
   Terminals
   1	2	Approx. 532 - 588 kΩ [at 20°C (68°F)]

   CAUTION: Do not use any knock sensors that have been dropped or physically damaged. Use only new ones.

Is the inspection result normal?
