O2 TEST
There are no valid static tests to perform on the oxygen
sensor. The sensor should be diagnosed using Digital
Wrench.
First, verify if there are any stored codes for the oxygen
sensor.
NOTICE
The ECU must first run though the O2 sensor time
delay before a trouble code will be set. This may take
several minutes at idle to occur.
Short drive cycles and cold temperatures will both affect
the delay time of the O2 sensor (increases the delay).
The delay time ensures the oxygen sensor heater has
run long enough to provide accurate data.
O2 REPLACEMENT
1. Disconnect the harness going to the oxygen sensor.
2. Remove the oxygen sensor from the exhaust pipe.
3. Install new oxygen sensor. Torque sensor to
specification.
TORQUE
Oxygen Sensor:
13 lb-ft (18 Nm)
4. Connect the harness going to the oxygen sensor.
