P1162 1997 Honda Civic Code - Air/Fuel Ratio Sensor 1 Circuit Malfunction

Quick Answer

The P1162 diagnostic trouble code (DTC) for a 1997 Honda Civic indicates a malfunction in the Air/Fuel Ratio Sensor 1 Circuit. Common causes include Faulty Air/Fuel Ratio Sensor 1: The sensor itself may be malfunctioning, leading to inaccurate readings being sent to the ECM, Wiring Issues: Damage or corrosion in the wiring harness connected to the sensor can disrupt the signal being sent to the ECM, Poor Electrical Connection: Loose or poor electrical connections at the sensor or ECM can cause intermittent signal loss. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
