The check engine light came on my truck - code 52. So last night I go and check on the knock sensor and it looked like it was broken. I must have banged it when I changed out the fuel filter. Is there a place where I can get one at a decent price? Will it harm anything if I drive the truck with a faulty sensor for a while? What effect does this sensor have on MPG?

truck = 92 22re

TIA,

my sensor went bad but would only turn the light on once and a while. when it came on if i did not reset the computer my gas mileage went to pot.

Just how "broke" is it? It may still function being cracked etc... It should not harm anything to drive with a bad sensor. Make sure the sensor is screwed in tight to the block also.... A loose one will set off the code, also if you stall the truck sometimes it kicks the KS code.

Just a little broke... It is really messed up!

Also noticed when taking the picture that the fuel filter was not bolted down at all. I must have left the bolts loose when I changed out the filter. An expensive mistake! I read another post where the filter can be placed (I believe) in the fender well -- that is what I am doing next.

On the Knock sensor... Do the numbers stamped on the side (on the replacement) need to match what I have on the truck now? Or will it work as long as the connectors are the same? There is one on ebay with a similar plug but #'s seem to be different. Seller says it will fit my year truck.

Thanks,

The numbers probably don't have to match... Check it out on the electronic parts catalog linked in the FAQ and see what the numbers there say.

Thank you all! I ended up bidding on one on ebay, got it for $29 shipped. Number did not match but the parts looked identical, truck is working fine now... Thanks again.
