Hey guys,

I'm about to replace the after-cat o2 sensor on my Spyder and was wondering if anyone can share a link or provide their insight on the procedure? I've tried an extensive search already and came up emptier than the soul of a porn star :p

Thanks in advance y'all! :cool:

BUMP- could somebody who replaced the post-cat O2 sensor weigh in with their insights? The sensor looks like it's pretty easy to access but I'd like to know the specifics of the replacement procedure (o2 sensor torque specs, any pertinent precautions to take, etc). Thanks! :)

Why not. Short version.

Take out the right taillight. To do this, unscrew the two M10-screws. You can leave the wiring on the taillight, and just put it aside, or unconnect the wires, and take the whole taillight out.



Now you see the grey connector, unconnect it. Do not pay attention to the routing of the wiring ! This is not the correct routing !



The wires are fastened at three points, on top of the plastic bumper, and in the middle and the bottom of the real (metal) bumper. Some small japanese hands should come in handy.



If you have disconnected the wire, you can unscrew the sensor. No need to jack up the vehicle, you can reach the sensor and the bottom-clip easily from beneath the car.



Put your new sensor in and fasten it (sorry, no torque specs) and use athe three clips to re-fasten the wire. Do not use the hole on the right, you will not be able to put your taillight back ! The correct hole is the left hole.

Mount the tail light.

Walk to the fridge.

Get a beer.

Open the beer.

Celebrate your victory !

Put some anti-seize compound (I think both copper and molybdenum based compounds are ok for this application) on the threads of the sensor before you install it.

Anybody knows what the part# is for this oxygen sensor? Are they all the same O2 sensor or is the after-cat o2 sensor and before different?

It's
  • (Bank 1 Sensor 1) Header Right hand side
  • (Bank 1 Sensor 2) Header Left hand side
  • (Bank 2 Sensor 1) Main cat

Universal sensor's

With connector:
Bosch 0 258 986 606
Denso 234-4624

Without connector:
Bosch 0 258 986 602
Denso 234-4209
Unifit OX 104

Get one without a connector, then you will always have a long enough cable. (difference between the sensor's is just cable-lenght.

I think there is an error here. Bank 1 sensor 2 should be the down stream (post cat) O2 sensor, and bank 2 sensor 1 is the second fuel trim sensor.

You are right, I checked it. But I can't edit my post.

Correct is:

It's

(Bank 1 Sensor 1) Header Right hand side
(Bank 1 Sensor 2) Main cat
(Bank 2 Sensor 1) Header Left hand side

  1. What could be the problem if code check engine still showing after replacing sensor?
