Code P1167 2005 Nissan Altima Sedan Description
The P1167 diagnostic trouble code (DTC) for a 2005 Nissan Altima Sedan specifically refers to the Heated Rear Oxygen Sensor 2 Maximum Voltage Monitoring Bank 2. This code indicates that the engine control module (ECM) has detected a high voltage condition in the heated oxygen sensor (HO2S) located downstream of the catalytic converter on Bank 2 of the engine. The HO2S is responsible for monitoring the oxygen levels in the exhaust gases and providing feedback to the ECM to adjust the air-fuel mixture for optimal combustion.
