Has anyone ever had the problem of the SES lighting up then kicking on the high speed fans? I know the fan sensor is located on the water pump housing on the LT1. Could this be the culprit? I had the codes scanned it it came up with a code 29- Secondary Air pump inop and a code 42- Ignition problem. I don't see where any of these codes would cause the fan to come on. It really drains my battery and causes the car to run a little rough. Any help would be GREATLY appreciated.

dont know for sure but check the under hood relays.

I had to replace my air pump due to this. No big deal.

Even when I remove the fan relays the computer overrides them and turns the fans on. My car does not have an air pump because I removed it when I installed the long tube headers. The air pump will cause the computer to kick on the fans?

That could be possible.

My fans came on all the time (sometimes with a SES) or just sometimes when my coolant temp sensor was loose / broken...
Its some kind of emergency procedure to prevent the engine from overheating because the pcm doesn´t know the coolant temperature.

Anything is possible. A taillight bulb that has been removed will set off your airbag light.

Same problem here...

My car always blows that 20 Amp Air Pump fuse and then the SES light comes on when driving and the hairdryer starts up.

Funny thing is: Only when driving.

As soon as i stop on a stoplight, after about two seconds SES goes off and after about 10 seconds of idling the fans stop. Funny thing.

Goes i have bad air pump? Didn´t even know i need sumthing like this

Rampage,
I have an air pump sitting in my basement. I do not need it now. I would give it to you. I actually fixed mine the other day. I just put the air pump relay back in and hooked up the EGR Valve. Problem solved. Goes back to my old saying that I seem to never follow "Leave well enough alone!"

Sure! Would help a lot!

Any other parts you want to sell by chance??

I am starting to look at a complete rebuild, as the more i look into the car the more parts needful of replacement i find ;(

Hey Rampage, you have no cat - so why do you need a air pump?

For the darn fans to stay off. Or any way to bypass it

Also you are wrong. I do have a cat. She´s 5 years and black and white, maybe she´ll need it.

J/K, i guess i´ll return some things to stock, especially if i want the car to be registered normally someday in the far future...

Blowing up your cat (to double size or whatever) is for sure against the law

Actually she´s asthmatic, so already heavy breathing...

Wanted to give her some performance intake, too!
