Code P2097 Cadillac Description
The P2097 code for Cadillac vehicles indicates that the fuel trim system on bank 1, which is the side of the engine where cylinder 1 is located, is detecting a high limit condition after the catalytic converter. This means that the engine control module (ECM) is detecting that the amount of fuel being injected into the engine is higher than what is considered optimal for proper combustion and emissions control. This can lead to issues such as decreased fuel efficiency, increased emissions, and potentially damage to the catalytic converter over time. The underlying cause of this issue could be due to a variety of factors, including a faulty oxygen sensor, a vacuum leak, a clogged fuel injector, or a problem with the fuel pressure regulator.
