1995 Buick Riviera P1655 Code Explanation: EVAP Purge Solenoid Control Circuit
I'm looking for information about the P1655 diagnostic trouble code on my 1995 Buick Riviera with a 3.8L SC engine. I've searched extensively but can't find clear details on what this code means or how to address it. Could anyone provide accurate technical information? Thanks in advance.
While I'm not entirely certain, a GM-specific reference indicates that P1655 corresponds to the EVAP Purge Solenoid Control Circuit. This code typically points to an issue with the evaporative emissions system's purge solenoid, such as wiring problems, faulty sensor readings, or internal solenoid failure. It's important to inspect the harness connections and ensure proper grounding when troubleshooting.
