i have a 92 hatch with a jdm d15b vtec with a p28 auto ecu conv. to manual. every once in a while i was getting a cel, so now it comes on all the time, also my a/f gauge stopped working. i pulled a code 43. i was told by honda it was a fuel supply code but chiltons sayes its a heated o2. which is it?

it is an o2 senor. it reads as a fuel system problem. it is an o2 sensor though

im not doubting anyone, i just wanna be sure before i drop $165 on a new sensor. thats the cheapest ive found around here. is this right?

If your fuel presure is within spec and there are no large vacuum leaks, it's usually a bad o2 sensor.

well i dont have fuel press. gauge so i dont know on that, but there are no leaks. the car still runs and idles fine, just getting cel and the mpg is a little worse

Its probably a bad o2 sensor. That may be the reason why your air/fuel gauage isn't working cause it reads off of that sensor. And a bad o2 doesn't properly do your air/fuel mixture and that may be the reason why your getting shitty mpg.

has anyone else experienced this, with the a/f gauge and all?
