The "knock sensor" adjusts timing. So bent valves could result if timing is way off. Your car would quit running before timing was that far off. $700 sounds high shop around.

Location of knox sensor


HI, they are located under intake manifold.
The first sensor is located in the front of the engine and the second sensor is located in the back of the engine. Remember to replace the intake gaskets once you replace the sensor/s.

Horn ha stopped working completely; was told by mechanic that it needs a sensor which costs $300+; what happened to the old replace the fuse?


Why would a horn require a sensor?
I don't buy it.
Tell us more on the make, model, and year.
If someone told me the horn was $300, I would wire a new horn and button on the dash for $15.

I have been told that my car's Knox sensor needs replacement @ £300. Its an Audi A4. the car is running alright though. Is it essential?


If there is excessive vibration you can get a false positive on setting a code. This sensor helps your computer set the timing of the engine for maximun fuel economy and to keep it from pinging (sounds like marbles in the engine). If it is truly faulty the computer will go into fail-safe open loop mode which would reduce economy. If it is running as good as before and your mpg have not dropped and you do not hear any detonation then drive it and save the pounds. Make sure the wire to the sensor is connected well.

I am trying to locate the coolant temp sensor so i


It should be located on the back of the motor near the cam sensor. Not near the firewall, but where the trans meets the engine.
