Since i got my car out for the summer, my fans won't go off and the SES light stays on...i got it scanned today and it showed the AIR code...and trouble code 11 MIL...wtf is that? Hayne's doesn't list that one...they start at 13...now the AIR code is because i removed the AIR system and last week thought i could remove the relay for it without any problems..bad idea. but the SES light and fans were going before i pulled that out...
Just found my answer...it's a lamp fault..i think i fixed that problem though...
but i still don't know why my SES light and fans are staying on...especially if there isn't a problem according to the scan tool...GRRRRRR

 

I'm a little confused... you said you have an SES light, and the code for the AIR system, then you said "especially if there isn't a problem according to the scan tool". Do you have DTC 29, or don't you?

If you removed the AIR pump, you need to leave the relay in and a good fuse in the circuit. That will eliminate the light, codes and fans.

For a decent list of codes, try the one in my online Scanner writeup... it's got DTC 11 in it.... :

Scanner Writeup

 

either i worded that wrong or you didn't quite follow...
I put the relay back in..so that should take care of the AIR trouble code (29).
but it was also showing trouble code 11...MALF Lamp fault or something...i dunno what that could be, but i don't think a bad bulb is gonna throw the service engine light on.....what i was trying to say is that unless code 11 is gonna kick on the fans, and scan tool wasn't listing any other codes , therefore not showing any problems...then i don't understand why my fans and SES light are staying on.
Any ideas?

 

But did you actually check to make sure it eliminated the code?

 

MIL is a burnt out dash light. In the case of my car, the SES light was burnt out. I swapped bulbs with the skip shift one and MALF 11 was fixed.

 

but is MALF 11 gonna throw the SES light and fans on or not?

and no i didn't make sure the AIR code was cleared...but that doesn't make any difference...this problem was occurring before i ever touched that relay....I only brought that up in the first place to state what codes i had thrown recently

 

Yes, MALF code 11 can set a SES light and set a code. It can be caused by the bulb being burned out. The PCM senses voltage potential from the IP fuse number 9 through the bulb to terminal D9 at the PCM.

Another cause for setting MALF 11 is a shorted to ground situation at the output field service enable circuit at the ALDL. That circuit (448 blk/wht) begins at pin D20 and connects at the ALDL port number 6. If that circuit is grounded it to will set code 11. The last situation that will cause code 11 is a faulty PCM itself.

In all cases concerning MALF 11 the lamp will not illuminate. If your fans are coming on then it sounds like it is either that the output enable circuit is grounded or you have a bad PCM. Enabling the field service mode will turn on the fans.

 

if the PCM is faulty, how could the car still be running?
and what would cause the PCM to become faulty to begin with and do i need a new one?

The SES light sometimes goes off for a few minutes then comes back on...if the PCM was bad, would it be doin that?
I appologize for my ignorance..i really know nothing about this.
What should I do?
I'm supposed to be getting a new PCM to go with my cam and heads (not yet installed)...and I'll be sending mine when i receive the new one to cut down time...so that would take care of that problem...

No matter what speed I'm going, if i let off the gas, the RPMs drop down to under 1k as though it was in neutral. This problem started about the time i wired up the "hidden shift kit" last summer..i accidentally sparked one of the wires going to the PCM. That's about when that weird tranny problem started...do you think this is all related?
I'd hate to think i need a new PCM and Trans...but as my luck goes..probably do..
But apart from not staying at the correct RPM level, the tranny doesn't miss or slip or anything....just seems to drop into neutral when i let off the gas..whether I'm goin 10 or 100, in D or OD...i know the tranny is electronically controlled..so wishful thinkin would like to have me believe i just screwed up the PCM

 

Trevor I will email you a couple pages of DTC 11 diagnostic charts from GM for you to look at. The PCM can be at fault and the engine will still run. Or it can be so that it won't run I have seen both. Just like having a broken neck, when I was a kid I thought if you broke your neck you died, but thats not always the case.
