REMOVAL PROCEDURE
See Attachment at bottom of istructions for picture

IMPORTANT: Take care when handling the heated oxygen sensor (HO2S). The in-line electrical connector and louvered end must be kept free of grease, dirt or other contaminants. Also, avoid using cleaning solvents of any type. DO NOT drop or roughly handle the heated oxygen sensor/catalyst monitor. A dropped sensor is a bad sensor.

The heated oxygen sensor may be difficult to remove when the engine temperature is below 48°C (120°F ). Excessive force may damage threads in the exhaust manifold or exhaust pipe. [*]1)Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.[*]2)Disconnect the HO2S electrical connector.[*]3)Carefully back out the heated oxygen sensor.
[ol][/ol]INSTALLATION PROCEDURE

IMPORTANT: A special anti-seize compound is used on the heated oxygen sensor threads. The compound consists of graphite suspended in fluid and glass beads. The graphite will burn away, but the glass beads will remain, making the sensor easier to remove. New or service sensors will already have the compound applied to the threads. If a sensor is removed from an engine and if for any reason is to be reinstalled, the threads must have anti-seize compound applied before reinstallation.[*]1)Coat threads of heated oxygen sensor/catalyst monitor with anti-seize compound P/N 5613695, or equivalent if necessary. NOTE: Refer to Fastener Notice in Service Precautions.[*]2)Hand start the heated oxygen sensor. Tighten Tighten the heated oxygen sensor to 42 N.m (31 lb ft ).[*]3)Connect the HO2S electrical connector.

thanks man i really appreciate it. anything else you would recommend/ i need to know? and where exactly is it located? thanks!

 

I believe it's on the back of the header. Bank 2 O2 sensor is passenger side.

 

The picture in the attachment in my previous post shows the location, basically on the passenger side exhaust manifold. Arrow on picture points to front of engine.

 

thanks guys i really appreciate it!!
