Not much of a gear-head. Trying to learn though.
CEL popped up.. p0135.. heating unit pre-cat o2 sensor. Car has 77k miles, my plan was to just replace the sensor all together. Curious if anyone in the area has done this and might be willing toss me some guidance.
Ive tried searching on here.. i see nothing but trouble shooting guides.

If your going to replace:It's really simple, make sure the car is cool and use a lot of PB blaster.

Having a socket like this one makes it a lot easier

I'm putting my CAT back on next weekend and an oil change for the S, So I'll be reattaching the 02 sensor on the CAT, feel free to join and we can replace yours also.

Anything NOT Bosch.

Why not Bosch?

Because their stuff is not very reliable and not built to the same tolerances as the Denso stuff in our cars. Bosch is responsible for most of the electrical headaches in German cars.

Even simple non-heated Bosch O2 sensors back in the day on the CRXs would give problems for people.
