help changing oxygen sensor 2

First time on this forum.I have the Service Engine Soon light on my 04 Titan SE. I went to Auto Zone and this is what they told me.
P0158 The PCM has determined that the input voltage from oxygen sensor 2 in bank 2 is too high for current operating conditions.

The guy at Auto Zone told me to change the oxygen sensor. First of all I have no experience with oxygen sensors. Is this something I can change myself? If so where is it located?

Thanks for your input.

Re: help changing oxygen sensor 2

An O2 sensor can be a pain to change sometimes. Crawl underneath there and look to see how much space you have. Then when you go buy the sensor, also buy the socket or tool that will make removal much easier!!!

Why is there never enough time to do it right the first time,
But always enough time to do it again?

Haven't seen one, but if it's the 2nd sensor it is easy. You just jack the truck up on one side, slip in a jack stand and roll on under it. Locate the sensor by looking for the object screwed into the exhaust pipes under the cab. Look on either the left or right side depending on which code you got. Disconnect the quick connect harness and undo the sensor with either the specialized tool or a 7/8" / 22mm wrench if I recall correctly. Put some O2 sensor safe anti-seize on the new one if it doesn't already have some on the threads (Bosch sensors and the OEM Nissan sensors have some already) and tighten down the new one. Attach the harness and you're done.

You may want to put some penetrating lube on it and let it sit first. They can be quite difficult to loosen at times.

If it's the first sensor, it is attached to the exhaust manifold and you will need to undo your wheel well liner to get to it. Those are more of a pain and you will likely need the special tool and some universal joints and extensions for a ratchet. The procedure is the same, just a harder to get to location.

You may or may not need to reset the CEL (engine light). If it doesn't go off after driving up to 50 miles, reset with a code reader like Actron, programmer like Superchips, or use the manual procedure you can find on this site using a search.

Personally, I like using an open-ended wrench on the 2nd sensors because it is easy to get one on there and you have more leverage. Use whatever works.

Engine - Nismo CAI & headers, Magnaflow high-flow cats, Magnaflow catback, UpRev
Suspension - F/R swaybars, Bilsteins, PRG endlinks & Minilift
Brakes - PowerSlot rotors and Hawk brake pads
Other - Nismo gauge face, Autometer Trans, Diff & Coolant gauges, Mag Hytec diff cover, PML transmission pan, etc
