you will have a knock sensor code and the car will run slugish. when a knock sesor code is set its retards the timing so the engine will not detonate. the easyiest way to fix it is relocating the sensor.

What is a 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.


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.


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.


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.


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.


How important is it to fix a damaged knock sensor?

Allowing an engine to ping excessively can do serious damage.


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 does the engine code knock sensor mean?

A knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor wasn't operating properly, so that it was always indicating a knock, the engine computer's response may have been to change the ignition timing on your engine. The knock sensor generally threads into the engine block. This code may show up intermittently or the Service engine light may be lit constantly. You may notice drivability problems including a lack of power and perhaps some hesitation. There may also be other symptoms. * The knock sensor is faulty and needs to be replaced * There is a wiring short/fault in the knock sensor circuit * Check the resistance of the knock sensor (compare it to factory specs) * Check for broken/frayed wires leading to the sensor * Replace the knock sensor
