A faulty knock sensor is unlikely to directly cause your cooling fans to stay on. The knock sensor primarily detects engine knock or pinging to adjust ignition timing, while cooling fan operation is typically controlled by the engine's temperature sensors and the engine control unit (ECU). However, if the knock sensor is causing the engine to run inefficiently or overheating, it could indirectly lead to the cooling fans running more frequently. It's best to diagnose the cooling system separately to identify the actual cause.
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.
The knock sensor is a passive device that has no effect on engine idle.
Generally they are located close to the themostat and have two wires attached. The year, make, model and engine would help.
No.
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.
No. The knock sensor's purpose is to detect spark knock (pinging) and send a signal to the ECM to temporally retard the timing until the spark knock stops.
what will happen if you install a knock sensor that isn't called for that make & madel
The knock sensor has no effect on idle. It has no effect at all unless it is triggered by detonation. It is a passive device.
Drain cooling system. Carefully disconnect wire to sensor and use wrench (7/8 I believe) to carefully remove old and install new, reconnect wire. Alse make sure threads of new sensor have sealant on them
if a knock gos bad can your car go off
No it will not cause it not to run.
A knock sensor detects engine knock in the motor(aka pinging, detonation, or uncontrolled explosions. it basically means the motor is about to blow up or potentially could.) the second part to a knock sensor is that it keeps the ignition timing as advanced as possible to make the most power without making engine knock. So if you have a bad knock sensor or have a check engine light form a knock sensor your car will be slower. this is when your car goes into LIMP mode which is basically a preset running condition which is safe for the motor.
