Acura Repair: O2 Sensor on 2001 Acura TL, acura tl, catalytic converter

Question
How much labour is involved in replacing the O2 Senosr?

Answer
Hi Todd,

The O2 sensor is easy to replace, it is located under the car on the exhaust on the catalytic converter. First disconnect the negative post from the battery, There are 4 wires connected to the O2 sensor, unplug the O2 sensor from the connector (if you follow the wire you will find the connector about a foot away from the O2 sensor), after disconnecting the connector you can remove the O2 sensor, you will need a wrench I can't recall off hand what size it is but I believe it is a 7/8 wrench. Replace the O2 sensor with the new one, connect the connector and attach the negative post back on the battery. Make sure you have the security code for your radio before disconnecting the battery.

Thank you,
Daniel
