Disconnect knock sensor harness connector.
Check resistance between knock sensor terminals as follows.
NOTE: It is necessary to use an ohmmeter which can measure more than 10 MΩ.

Knock sensor		Condition		Resistance
Terminal		Condition		Resistance
1	2	Temperature	20°C (68°F)	532 - 588 kΩ

CAUTION:

Never use any knock sensors that have been dropped or physically damaged. Use only new ones.

Is the inspection result normal?
