Sub Heated Oxygen Sensor

COMPONENTS FOR REMOVAL AND INSTALLATION

1. INSPECT SUB HEATED OXYGEN SENSORS.
(a) Cancel diagnostic trouble code.
(b) Allow the engine to warm up to normal operating temperature.
(c) Drive for 5 minutes or more between 80 km/h (50 mph) and and 100 km/h (62 mph) in D position.
(d) Following the conditions in step (c), press fully on the accelerator pedal for 2 seconds or more.

HINT: Do not exceed 100 km/h (62 mph), or diagnostic trouble code will be cancelled.

(e) Stop the vehicle, and turn the ignition switch to OFF.
(f) Carry out steps (b), (c) and (d) again to test acceleration.
If code Nos. 27 and 29 reappears again, check the sub heated oxygen sensor circuit. If the circuit is normal, replace the sub heated oxygen sensor.





2. DISCONNECT NEGATIVE (-) TERMINAL CABLE FROM BATTERY.

CAUTION: Work must be started after 90 seconds from the time the ignition switch is turned to the LOCK position and the negative (-) terminal cable is disconnected from the battery.
