Code P1162 Acura Description
The P1162 Acura code indicates a malfunction in the Air/Fuel Ratio Sensor 1 circuit. The Air/Fuel Ratio Sensor, also known as the oxygen sensor, plays a crucial role in monitoring the oxygen levels in the exhaust gases to ensure the engine is running at the optimal air-to-fuel ratio. When this sensor malfunctions, it can lead to incorrect air/fuel mixture readings, which can result in poor engine performance, reduced fuel efficiency, and increased emissions. If left unresolved, this issue can potentially cause damage to the catalytic converter and other engine components.
