the only sign is if it goes bad it should trigger the check engine light, you wont notice loss in peformance in engine. all it does is when there is a knock in a cylinder, from bad fuel, it leans back on fuel to stop the knock.
The knock sensor retards the engine timing when there is a knock or ping detected. This will make the car a little sluggish. It is rare that the knock sensor goes bad.
Yes it can hurt your engine to drive with a bad knock sensor. The knock sensor should be replaced as soon as possible.
If the sensor it'self is bad then NO.
The sensor is bad. A properly-functioning knock sensor allows the ECM to advance timing until it senses a knock. It then retards timing until the knock just barely goes away allowing for optimal gas mileage.
knock sensor is going bad or is bad
Ping.
No, the knock sensor only retards the timing when it detects the engine pinging.
if a knock gos bad can your car go off
NO it will not. If you have a knocking sound then you have trouble inside of the engine.
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.
A bad knock sensor would illuminate the check engine light and allow the engine to ping (spark knock). The engine doesn't shift, the transmission shifts.
Because there is nothing wrong with it. This is a common code that can relate to a number of components. The knock sensor itself is rarely the problem.
