knowing which engine would help us help you -


the purge valve located on top of engine, under the 'sight shield' - may stick open r closed... there was a special coverage policy- not sure of years involved- if you determine yours is bad ask dealer if your vehicle is covered, 3.6L?.

Let us knoe which eng and someone will help localize the component

Sorry about that I believe I have a 3.6L V- engine found out that their are two of them one in the front as you were saying and one in the back, how can I tell which one is bad, and the one in the front is it easy to get to under the shield and the back one where would it be located and is it it easy to get too Thanks

purge valve is in front on eng....vent valve is in back tank/canister area -

remove sight shield- R/S engine - above center coil - will have vacuum lines to help ID...

without a scanner I cant think of an easy DIYer check of the valve operation.. Is enging running rough?

you can change it- no major job - BUT ewplacing the component is not always the corrective action. could be more than a failed component.

Cadi is likely one of the most advanced of all vehicles on par wirh Benz in uniquie systems and 'logoc'.... recomend you find a shop specializing in cadi - before a major this would be a time to select.

I finally put my 07 Cad STS in the shop for the vent solenoid can anyone tell me if the solenoid is by the gas tank or do you have to take the gas tank down to get to it because I was told you have to take it down to get to the part and now that its been fixed I'm having a rough idle and you know how when you start your car up your engine light comes on then it goes out well mine doesn't come on all and go back out, is it possible that the mechanic perminatly turned my engine light out because he didn't fix the problem.

I doubt an AUTHORIZED Cadillac dealer would do what you suspect... BUT a easy free way to check would be take advantage of the Free code scans at Autozone et al part stores... FREE if there is an issue wuth the OBD system it will report - a code.

all that info will be explained im the scan tool manual, or visit the manufactures
web site - often different manufacturers use different 'names' for different information...

p0021 is an issue with VCT - wiring? solenoid? actuator?
