I Bought a new VAF and connection today... My SES light is still on and still getting...
VAF or MAF circuit input low
Evap emmissions control valve C fault
Evap emmissions control valve/solenoid failure
I bought a new maf a while ago, and now I bought theese and its still on.. Anyone else got any suggestions?

 

What did you do that initally turned on the ses light?

 

I havent done anything... I had Jesse recalibrate my ECM for 4:10 gears but, other than that nothing... Like I said I changed all those things and it still gets those codes.. Is there a solenoid that goes to the VAF?

 

i'll look that up for you about the vaf... is the maf a stock size and not descreened(not like it really matters)?... have you checked all the wires that lead to the vaf/maf from the pcm?

 

Do you have 2 pcms? or did you send jesse your stock one?

 

Stock one... I never had a problem with it.. That damn thing is bugging me.. I put a test light on it and there is no voltage going to the VAF..

 

Does the VAF have a solenoid that goes to it?

 

If it's any concession, I got a MAF low voltage code and light with my LT1 MAF extension harness, but it was because the harness was plugged (I think some can be) in backwards. The damndest thing. took forever to notice it, and it was another mech that did. Just walked up and said, "hey, look at that" <clip>

 

This sucks.. Its making my tuck run like ***.. And I cant do anything about it... Im thinkinjg of try another PCM and see if it comes on again..

then it's prolly in the tune...get another one sent your way and see if it all goes away....
