Hey guys I have a 1993 z28 camaro that is showing code 43. On day I was driving and the fans came on and the check engine light came on. I have long tubes with off road y pipe and full deletes with the exception of the ac. No rr on this motor. My question is with this code do the fans stay on all the time. As soon as i start the car the fans come on and stay on all the time or is something else going on that codes are showing for.

The fans come on with most codes. Why not fix the KS circuit that is causing the code? Performance is lowered with this code present.

I am going to fix it just was not sure if I had something else going on. Thanks for the info on the fans!

Hey guys one more question. If it is my knock modual that is bad since I have a 1993 camaro do I have to have the computer repaired. If so dose any one have a recommendation on a place that can fix this. I don't think I can replace just the modual on a 1993 computer.

If the code is being set from the KS, then no, just replace the sensor and you should be fine.

I'll find out just don't have the time to mess with it for a few more days.

ok so i had some time yesterday to look at the problem and it was the KS. So the problem is fixed. Also if anyone cares i was looking for some heated o2s for my 93 with long tubes part number afs 75 and found them at walmart for 27.33 each. They have to order them but way cheaper then every where else.

That is one place I did not check. Not surprised they sell everything cheap.
