Anyone ever heard of 2m04? I got one on the way into work. Just cruising along engine light comes on and I scan it with my scangauge and it tells me this. I can't find it on the normal websites.

Any help would be much appreciated.

ummmm, doesnt list a 2M04 code but they do have a 2A04. It has to do with the o2 sensors. If that is it let me know and I can paste the flow chart in here and you can print it off

 

I could have read it wrong this morning but I thought it said 2m04. What does 2a04 mean just in case. My rear O2's are turned off if that makes a difference.

Thanks

I had it read by another scanner and it showed 2A04 instead. Bank 2 rear O2. How does it see these if they have been turned off for 20,000 miles. And do I fix it by putting in a new one or having someone tune it out.

Many thanks.

just tune it out, def don't buy a new one
