service engine light

I have looked several placed and can't seem to find where the various codes would be. Once I get a scanner and get a code, other than calling Coachman, where can I locate what the code means?

Is it an F53? Has the air filter been changed.
I had this happen. Changed filter, cleaned MAF, problem solved.
Do as others have suggested get codes read.

That light indicates a problem with the emissions control system. Get it to someone capable of reading the codes and diagnosing the problem.

You need a OBD II scanner to plug in and read the codes. Then look up the code and it will tell you what system error is turning on the service engine light. Any thing else you will be just guessing at what's wrong. there are too many codes for anybody to guess what is wrong so get it read. Or buy a scanner and read it your self. Could be minor or major, you won't know until you read the code. Here is the one I have, works great.
Actron Scanner

I can't find the codes anywhere. I have a manual but can't find the code section. I'm hoping it's something easy like the gas cap. Do you know if there is also a check engine light as well as service engine?

Did you check for codes?

I ghave a 2006 epic coachman. The RV has a little over 20,000. The other day while driving, the service engine light came on. I checked all the fluids, water, canister is 3/4 full, Oil is light brown, newly changed, tranny is nice red color. gas cap was on, I believe tightly. Turned the RV off for 2 days and restarted and light came back on. I can't find anything that explains what might be causing this. Any ideas?

Had you just fueled it? Could the fuel cap be loose. Or, you could take it to a auto parts store, and have them hook it up
