O2 Sensor Install - OBDII Code P0138 - NGK 23132 - Project 2004 Jeep TJ Wrangler - Howto

In this video, I change out a bad oxygen sensor (Bank 1, Sensor 2
- Downstream) but this video will be helpful if you have a code that references other sensors.

There are four O2 sensors in my 2004 Jeep Wrangler with a 4.0L six cylinder engine:

Bank 1, Sensor 1 (upstream)
Bank 1, Sensor 2 (downstream)
Bank 2, Sensor 1 (upstream)
Bank 2, Sensor 2 (downstream)

Based on my research, I recommend only using NGK/NTK sensors as these Jeeps are known to be pretty picky. I can tell you that my install solved the issue, and no more check engine light (CEL) so I feel it was money well spent not having to try a Bosch sensor to find it may or may not work. Anyway...

Here are the NGK/NTK part numbers and amazon links if you need them. These are affiliate links, so it helps me a little if you decide to buy from them... but it doesn't cost you any more than it normally would. :-)

These are for a 2004 (what I have) only... see below for other part numbers. BTW... these prices are much cheaper than what I paid at the local parts store... but I didn't want to wait for shipping.

  1. While I have heard of the no touch rule on o2 sensors.. it is also important not to use non-o2 sensor safe RTV anywhere on the engine where the RTV fumes can get into the pcv system... That will kill an o2 sensor

    I think the no-touch rule is an old wives tell, personally. lol -- I was happy to see the pre-application of anti-seize... made it easy to make sure it was a compatible product.
