Knock Sensor: Testing and Inspection

Component Inspection

KNOCK SENSOR




Check resistance between knock sensor terminal 1 and ground.

NOTE: It is necessary to use an ohmmeter which can measure more than 10 MOhms.

Resistance: Approximately 500 - 620 kOhms [at 25 °C (77 °F)]

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