What is knock sensor?
A knock sensor is a device that senses detonation. Detonation occurs in the engine when the fuel begins to burn prematurely; it can cause substantial damage to the engine.

What problem could the knock sensor cause on your car?
If the knock sensor failed the CEL (Check Engine Light) would be illuminated and the engine may "ping" or "spark knock" under load. Serious "spark knock" can damage the engine if allowed to continue.
Will i damage my car if i don't replace the knock sensor when they need replacing?
the knock sensor cuts the engine out so it won't damage the car if not replaced, the car just won't work.
Which instrument should be used to test for combustion knock?
A knock sensor is typically used to detect combustion knock in an engine. It is a specialized sensor that detects the vibrations and noises associated with knock and sends signals to the engine control unit to adjust timing and prevent engine damage.
How does a knock sensor work?
A knock sensor is a piezoelectric device that senses the knocks produced in the engine. The knock sensor tells de computer to retard the timing in order to prevent piston damage and/or blown head gaskets.
Does the engine on a 2003 impala knock in the top of the motor if the knock sensor is bad?
The knock sensor just advances and retards the engine timing only. If there is a noise in the engine then you have engine are valve train problems. The knock sensor will not make the engine knock.
How important is it to fix a damaged knock sensor?
Allowing an engine to ping excessively can do serious damage.
Symptoms of a bad knock sensor?
There are no symptoms since the knock sensor doesn't do anything unless the engine is detonating, in which case it would do nothing and you would hear it. The knock sensor code is often tripped when there is a fault in something else since it's part of the same circuit. This is considered a "ghost" error code.
If knock sensor is broke off can you drive or does it have to be replaced?
You can drive the car but if the engine should ping (knock) under load, the knock sensor won't be able to tell the computer to retard the timing. Excessive pinging can damage internal engine parts.
What will happen if knock sensor is blown?
If your car would run lean the sensor would not be able to determine that and their could be engine damage.
What are knock sensor symptoms?
There are no symptoms. The knock sensor is a passive part that does not do anything if it's not activated. Knock sensors codes on the Villager/Quest are usually caused by some other component, not the sensor itself.
