Knock Sensor

Knock Sensor

Description
When all of the entry conditions have been met, the input signals from the two knock sensors are checked against variable upper and lower threshold levels that are dependent on engine speed. If either sensor input is outside the threshold, then a failure is registered. If a failure is noted on two drive cycles then the MIL will illuminate.





If the above table does not include details of the following enabling conditions: - IAT, ECT, vehicle speed range, and time after engine start-up then the state of these parameters has no influence upon the execution of the monitor.
