P2192: System Too Rich at Higher Load Bank 1

The P2192 code indicates that the engine control module (ECM) has detected an excessively rich air-fuel mixture (too much fuel relative to air) in bank 1 under high load conditions. This typically occurs when the oxygen sensors or fuel trim values show that the mixture is richer than the target. Common causes include faulty oxygen sensors, fuel pressure issues, leaking fuel injectors, a restricted air intake, or a malfunctioning mass airflow (MAF) sensor. The condition can lead to reduced fuel economy, increased emissions, and potential damage to the catalytic converter if left unresolved.
