COMPONENTS FOR REMOVAL AND INSTALLATION
1. INSPECT OXYGEN SENSOR.
- Cancel diagnostic trouble code.
- Allow the engine to warm up to normal operating temperature.
- Drive for 5 minutes or more between 80 km/h (50 mph) and 1OO km/h (62 mph) in D position.
- Following the conditions in step (c), press fully on the accelerator pedal for 2 seconds or more.
HINT: Do not exceed 1OO km/h (62 mph), or diagnostic trouble code will be cancelled.
- Stop the vehicle, and turn the ignition switch to LOCK.
- Carry out steps (b), (c) and (d) again to test acceleration.
- If code No.27 reappears again, check the oxygen sensor circuit.
