2009 Cadillac PO443 Fault: Purge Valve Clicking and Rough Running - What's the Cause?

Model: cadillac 2009 Fault Code: P0443 Posted: 2015-02-25 17:10

My 2009 Cadillac is showing a PO443 diagnostic code, and I'm experiencing constant clicking from the purge valve. The engine runs roughly under load. Should I replace the purge valve, or could this be caused by another issue? I want to confirm if there are any other underlying factors before replacing parts.

Are there any specific diagnostic codes displayed in the vehicle's OBD2 system? Please provide full details: year, make, model, engine type, and exact symptoms. The current post lacks clarity on key technical information.

The vehicle is a 2006 Cadillac STS with a 2.8L engine and PO443 code. Engine runs rough and the purge valve makes a constant clicking noise during operation.
