Cadillac Jim Posted September 14, 2010 Report Share Posted September 14, 2010 P0443 EVAP Purge Solenoid Valve 1 Control Circuit This tells you which solenoid has the problem, probably the one on the engine. The first thing I would check is the fuse for that circuit, the second is the connector and wiring harness. I have a different EVAP system on my car (1997 model year) and OBD DTC P0443 isn't in my factory shop manual. Anyone with 2000 model year FSM?
