SENSOR, OXYGEN

That's the OEM, plug & play, upstream (front, pre-cat) O2 sensor correct? 2006 Acura TSX.

Amazing price considering I've seen more expensive aftermarkets. .

That price is insane. Go on k20a and contact the guys at Autofair honda. That sensor isnt even a wideband theres no reason for it to be more than 150 bucks or so.

You can even get it on amazon if you want.

No kidding, I've seen it go for much more; stealerships. Anyways, I spoke with Bosch and their OE replacement is actually identical in that Acura just re-boxes them. So, the sensor isn't my problem.

Looking for a blown fuse as the original sensor, wires got tore up, likely crossed and caused a short. Unsure what fuse to look for though since nothing else has been affected (aside from the new front O2 sensor throwing a heater code).

Crap. I forget what fuse, most other Hondas are fuse 15 check that one.

But if you disconnect the sensor and probe the white wire and the black wire you should see voltage with the car on(from a cold start only). Same with the blue and black (blacks dont matter there just ground) but it should only be 5v I believe.

There is a fuse for it but I cant remember which one it is for sure for the TSX

I think 15 is the more typical one, but ended up being 4 on mine. Fixed both my CELs, wasn't getting power to the purge valve or O2 sensor.
