What brand does Honda use for their 02 sensors? Are the primary and secondary sensors the same? Will a different brand like Bosch be similar? Also if anyone knows what wire from the sensor goes into which pin position it would be appreciated.

 

The Primary and secondary are different part numbers.. but I think that's just because the secondary has the "gasket" or whatever it's called for the floorpan. A bosch will work fine if you figure out the numbers.. I have to check but on the OEM o2s green is heater power, white is signal, and the black across from each one is that wires grounds (across from green, is heater ground, etc).

Oh yeah, you will have to figure out the bosch wires

Also, their operating voltage is 0V-1V

 

Thanks Dave

 

Just called the dealership. $245 for one fuggin sensor!! Ummm...guess Ill just have to live with my CEL for now. Anyone know some cheaper sensors?

 

err sackdz finished my horribly written post for me. thanks

 

check w/ Mike K, I'm sure he can do better, albeit will still be a ripoff from the dealer regardless

 

yep, mike k is def cheaper than that.. I got my new primary o2 from him.

 

I have read somewhere that if you clean the sensor with brake cleaning fluid it can start working properly again.

BTW, I am going to be removing my header this weekend and have heard that it can sometimes be very difficult to remove the oxygen sensor for the header. Any tips on this? Should I buy a specific tool for this?

 

The factory one is made by Denso. Mine threw a cel until I cleaned it with brake cleaner.
