Does anyone know which fuse controls the obdII port under the steering wheel?

I have a CHECK ENGINE light but my code reader just says error (code reader works on my Land Rover).

I saw a thread in the e series forum where someone had a similar problem and it was with a fuse related to the OBDII port.

Thanks

 

have you tired looking at your fuse guide?

 

I can't find it

Just got this car 3 weeks ago and it's already throwing CELs

 

well i know there is a pic of one on here somewhere if i come across it i will post it for you. try searching fuse diagram just saw some posts on it a few days ago.
btw what year c230 and how many miles

 

Found the diagram... and it's not listed! heh
On the E series it was shared with the cigarette lighter, but who knows.
I'll have to try and find another reader.

It's an '02 with 55k

It seems to run fine still so I'm assuming a sensor of some sort.

 

you can borrow one at advanced auto parts and some other car parts places

 

Good excuse to end up buying a better one ... and it works!


P0142 ... I think that's o2 sensor related but I'll start digging. I reset it and it didn't come back.

Temperatures have been well below freezing lately and it's been parked outside.

I should probably start a new thread seeing as this is kind of a different quesiton now...
