Just picked up a 2000 suburban 1500 (5.3 w/ a whipple) and it just threw a code the other day... P1415 Emissions (air pump?) any suggestions on what to look for or replace?

Thanks

 

according to a google search for P1415 you need to replace the Air Check Valve on the driver side. I THINK it's on the manifold but I dunno.

 

DUDE!.. I've must have looked at every wrong page the other night. Thanks for the tip--- I'll take a look!

 

Yes, if it's the same setup that they used to use, there will be an air injection pipe setup going to each exhaust manifold, and branching out into one pipe extension per primary. Where the hose screws on to the pipe setup, there used to be a check ball in there. Sometimes they would either stick or start to rattle...my old 85 MonteSS used to have a problem where one of the check ***** would rattle for a few seconds as the engine came up into operating temperature.

 

Thanks again... i haven't had time to look at it, but i just took the truck out and the SES light went off. At least i know where to start or what to change this weekend.

thanks again...
