Passenger side O2 sensor - ZR-1 Net Registry Forums

Bob Seliga · 01-27-2009

Got a code suggesting a problem with the O2 sensor. The drivers side was easy. Passenger side not so much. I got the old one off but my hands donfit between the block and the motor mount. Can it be reached pull the fender well apart?

Bob, drop the passenger side K-rail, and then the shielding that holds the sensor harness in place will come down. It's a tight fit and it seems like every car is different. But that should help. It has two 15mm bolts and two 13mm bolts holding the k-rail in place, plus the 19mm motor mount bolt.

Thanks for the information Jeff. I'll give it a try this weekend.

It is a pain in the azz!!! I ended up getting a O2 wrench that hinges. Jeff is the one that put me on to it. I don't think I could have done the job without it!! Then I had problems with the wire harness being too short -----hope you don't have that issue. Good luck.

Extended angle needle nose pliers and a long flat head screw driver will reach. But you still have to do what jeff said to make room.

Thanks for all the advice. It wasn't as bad as I thought it might be. A few more things on the list and I'll be back on the road.
