Alright since the post that showed all the diagnostic codes is gone, I'm kind of screwed on one of my error codes. But I found a couple of them (yes a couple I got 3 error codes) Can anyone tell me what exactly is involved in resolving these error codes (cost, damage) And also I can't find error code 0512 anywhere, anybody know what it is? Thanks.

Error codes I got:

0504: Automatic Transmission Control Unit Signal to ECU
0512: ?????
0402: Fuel Tank Temperature Sensor

Solo950

From my Haynes manual: 0512 -> "Downstream oxygen sensor high voltage fault". I hope that helps.

Thanks! No clue what that means though. I know I don't have to replace it cause I just bought a new O2 sensore a month ago. Is the voltage all out of wack? how can that be solved? The thing I'm most concerned about is the transmission code.

I think it refers to the O2 Sensors on the Y-Pipe.

Yup it is the rear O2 sensor, but I'm veryu worried about the transmission error code. Anybody ever seen this one or had to deal with it. Or would know what is involved with this one (cost, labour....)

The post is gone, but the info is still in the forums.





Are you sure? Did you do a forum search?

The seventh post answers this question.

The second post in that search answers your question. I'm surprised at your contention that you couldn't find anything on it at all.

Now this is the one that little info is available on. This was the only post that had anything on it:

Just using common sense and with me being a complete idiot on doing exhaust upgrades, have you done any exhaust (y-pipe, etc.) installs recently? It almost sounds as if all 3 are related to recent exhaust work, with just simply damaging the wrong sensors at the wrong time.

I haven't done any exhaust upgrades at all. The only thing I did was put in a cone intake that's all. Could this be causing it?
