Thread: Removing the Rear O2 Sensor and Getting Rid of the CEL

Got a link?

Just buy a B13 and call it a day.

Haha someday mang

I'm thinking about doing this....

Maybe it will work

Vadim,

I don't have a link, but you would need only to determine what the value of the o2 sensor's resistance is, on a normal/correctly operating vehicle. Then just merry that up with the proper resistor on the harness, for the signal wire. Obviously don't need to worry about the heater wires, unless they're part of the check to determine whether the o2 sensor itself is working or not.

It's still early in the morning, so I'll do some digging in the FSM for you when I get a chance, to better explain what I'm talking about.

Sweet thanks TeKKiE!

See I would just get it replaced, but my cat is kinda rusted and the O2 sensor is rusted onto it ... some wires ripped on the inside of the O2 sensor... I might just take a lot of WD40 or PB Blaster and try to unwrench it...

For money well spent on a rear o2 sensor, I would invest in getting your ECU basic tune by Calum, ask to have rear o2 remove and speed limiter remove if you have a stock b14 ecu.

Thats very good idea, if anyone decides to buy a new downstream O2 sensor, $120ish retail, better get an ECU...

I would go that route, but since I have the 99 ECU, I will need a new ECU, modify the harness, and I'm planning on a real time

Look at this, I think this might be the way to fix it...

Keep in mind that the resistor mod doesn't ALWAYS work. Calum did the mod to my realtime ECU when he came down to visit, and it didn't work. I think it could be possible that I haven't done the re-wire by JWT yet, though. (95~97 ECU with 98+ o2 sensor.)
