Default Knock Sensor

I ran diagnostics on my 92 sse last night and it brought up the code for the knocksensor. Now I know this is a pain to get to and I'm sure it'* pretty expensive to have done for you at a shop. Is it something I should worry about now, or can I put it aside for a while?? Thanks

I'd go a step up in octane on fuel for now. You'll be ok for now.....but it'* not something you want to go for awhile. The cooler weather will help alot, too. don't forget, though, you're also EGR-less in 92, so it'* a bit more critical for you when things get hot.....EGR, timing, all that stuff factors in to heat....and can cause burnt exhaust valves.

Not critical right now, but worrysome, yes.

The sensor is on the back side of the block and costs about $20 from discount or autozone..... Let us know hoe its running..... Will'* wright if it does have spark knock and you keep driving it, it coild result in burned valves and or burned piston-pistons.... Be careful.... :?
Pistons rarely go! The Valves will burn out long before the pistons will.

Increase octane and, as long as the rest of the wiring checks good, replace the sensor. Its cheap.
