Code P014A Cadillac Description
The P014A diagnostic trouble code (DTC) for Cadillac vehicles refers to a delayed response from the oxygen sensor (O2 sensor) located in Bank 2 Sensor 2, indicating a rich to lean fuel mixture transition. This sensor is typically located downstream of the catalytic converter in Bank 2, which is the side of the engine that does not contain cylinder 1. When the O2 sensor detects a rich to lean transition taking longer than expected, it can indicate an issue with the air-fuel ratio in the exhaust system.
