ok, so i just replaced mine today and the check engine light came on again with a different code. so did i get the wrong one? so i searched and read and here's what i think is right, please corrrect me if i'm wrong, but they are bank 1 sensor 1 (right near the header) bank 1 sensor 2 (going int othe cat.) and bank 1 sensor 3 ( in hte exhaust pipe after the cat.) i replaced the first one, i think the code was something like P0175? there's a service bulletin on it, and i got the ECM update. now the light came back on and has code P0137, so i just wanna make sure i gothte right one. thanx for any help... -steve

 

Just a thought,

On other Honda forum sites, it has become evident that inexpensive "universal" O2 sensors (or brands other than Denso or OE Honda) don't work very well. Too bad, because they cost 1/3 the price...

Where did you source your sensor?

 

it's an NTK (same company as NKG) so it shjould be ok, it was $120, so i didn't cheap out on it. i have yet to drive it today and see if it comes back on...

 

I thought Denso was OE (certainly true of our CRV, not sure about the Fit)

Here's Hopin'

 

3 o2 sensors?
i think there is only 2
on teh header, before the cat
and there is one after the cat.
OBD-II Trouble Code: P0137 Oxygen O2 Sensor Low Voltage (Bank1, Sensor2)

your old (first) CEL was this one

chances are it was not your o2 sensor that was the problem.

what other mods do you have on the car?
