2003 Saturn Vue AWD V6 P2097 Fault Code: What Does It Mean and How to Fix?
I own a 2003 Saturn Vue with AWD and a 6-cylinder engine. Recently, the Service Engine Soon light activated, and the diagnostic trouble code (DTC) retrieved is P2097. Can anyone provide insight into what this code means and how to resolve it?
P2097 indicates that the post-catalyst fuel trim for Bank 1 is too rich, meaning the engine is running with an excessive amount of fuel after passing through the catalytic converter. This can lead to increased emissions and potential damage to the catalyst. Common causes include faulty oxygen sensors, clogged fuel injectors, or a malfunctioning fuel pressure regulator.
