5. 2ZZ-GE:
REMOVE KNOCK SENSOR
a. Disconnect the knock sensor connector.
b. Remove the nut and knock sensor.
6. 1ZZ-FE:
INSPECT KNOCK SENSOR
Using an ohmmeter, check that there is continuity between the terminal and body.
If there is continuity, replace the sensor.
7. 2ZZ-GE:
INSPECT KNOCK SENSOR
Using an ohmmeter, measure the resistance between terminals.
Resistance: 120 - 280 KOhm at 20 °C (68 °F).
If the resistance is not specified, replace the sensor.
