Details:

Step 5 - Use a small wire brush to help clean the threaded port ensure proper seal of new sensor. There're many different codes for specific functional failures, which are NOT necessarily relevant to the sensor. How to install the oxygen sensor. Step 1 - Some sensors are equipped with a heat shield that must be removed before the sensor removal, this is performed by removing any mounting bolts.

Step 3 - Then, locate and disconnect the wiring connector, this step should be done before removing sensor if is still attached. Oxygen Sensors Location. If the sensor is good, further diagnosis required. Gently install the new oxygen sensor by hand while keeping wiring and connector free from bends.

The following information is for instructional and guidance reference only. Check engine light on A reduction in fuel economy. Must Know Before Buying. If the car has diagnostic trouble codes, they will need to be cleared.

New List Item. Note: some replacement sensors have a universal electrical connector that must be configured to the wiring of old sensor. If Check Engine Light is on or an OBDII Trouble/Fault code occurs after installation, check the sensor with a voltmeter as below. ONLY a defective sensor after tested by voltmeter is applied to manufacturer warranty.

Step 2 - By using a regular socket it minimizes potential damage to the sensor body and threads, this technique helps avoid stripping old upon removal. Your catalytic converter fails unexpectedly Exhaust emissions reach undesirable levels.
