Air Control Valve - 1990 Seville - Service engine soon

[erik.lavalle]

Hi all - any resources to either find the apparently discontinued part, to rebuild these air control valves, or to short circuit the computer control module to get the dash light to go off? My dealership can't find the part, nor did some of the larger Cad parts companies, but they did say it wasn't hurting anything, but the light is annoying. The part number is 17090215.

Air suspension?   Did you check Strutmasters?   Seems like they were a company that made non air replacement struts for many applications and part of the set was a plug in module to make the computer happy.

I think you are referring to the AIR valve assembly that manages the pollution system, not the air shock pump correct?    If so, then please check the vacuum lines running to the ports on the valve assembly.   They dry out and effectively become useless.  You'll notice as soon as you touch them the black material transfer to your fingers.   Replace those and you may solve your problem.   Do you know how to enter the troubleshooting mode to reset the warning lamp?

Hey there - yes, I am referring to the emissions control system, not suspension. I haven't checked those hoses, I can confirm with the dealership that that isn't the issue. Assuming it's not, I still need to see if someone can either rebuild these components or supply something that performs the same function.

Remember it could also be a check valve, or AIR pump.
