View Full Version : O2 sensor question

02-05-2014, 08:29 PM
I am looking at replacing the passenger side pre cat sensor on my 2.8. While the driver side sensor is
very accessible the other seems very tough to even see, let alone replace. Has anyone done this and can
you describe how you did it?

On mine, I removed the air intake hose, pushed a lot of wires out of the way, and used a crows foot (22mm I think) with a 12" extension. It is hard to get it especially if it hasn't been out recently.

I've done it last weekend and it's quite simple.
Remove some stuff so you can slip your hand to reach the O2 sensor ( clearance for your hand is the only hard part)

I used a Bosch universal that I soldered myself, did both sides, and the car is torquing way more now. (Bosch 15733 was used)
