DESCRIPTION
Some vehicles may exhibit MIL illumination with DTC P0325 stored in memory. This may be caused by water intrusion into the knock sensor element, which may result in momentarily lowered resistance.
NOTE:
This concern is more likely to occur with a one-pin terminal knock sensor.
A Knock Sensor Kit (with a two-pin terminal knock sensor) is available to correct this condition. Customers having this concern should have their vehicle repaired using the following procedure.
REPAIR PROCEDURE
1. Verify customer concern.
2. Unplug the knock sensor connector from the harness.
3. Inspect the knock sensor terminal to determine if it is a one-pin or two-pin terminal.
^ If a one-pin terminal is found, proceed to Step 4.
^ If a two-pin terminal is found, the knock sensor is a modified part. Troubleshoot according to the workshop manual.
4. Replace the Knock Sensor with a modified part (from the kit) according to Workshop Manual (section 01-40A) KNOCK SENSOR REPLACEMENT [KL].
NOTE:
To avoid coolant leaks, install a new intake manifold gasket and 0-rings (Water Bypass & Water Pipe) during knock sensor replacement.
5. Connect the Knock Sensor Wiring Kit harness in between the Knock Sensor and the vehicle harness (as shown).
6. Install the ground terminal onto the intake manifold with the bracket and bolt supplied in the kit. Tightening Torque: 15.7 - 22.5 N-m (11.6 - 16.6 ft-lb)
7. Attach the Knock Sensor connector to the bracket.
8. Attach the connector and harness of the Knock Sensor Wiring Kit onto the injector harness with the supplied tie wraps (as shown).
NOTE:
Cut off the excess portions of the tie wraps.
9. Verify repair.
