Default 1st CEL with light mods...HELP

Got my first CEL today.

Only mods are MBC @ 15.5 in third (never going over 1.1.mpa in 5th), and Vishnu's EMI adaptor.

Still runs great, nothing out of the ordinary.

What can be happening?

Could be a P0420 or something else.

You should plug a code scanner in and read it. Some auto stores like Autozone will do it for you. The dealer might charge you 60 bucks for that and probably wouldn't like what you have done. You can buy an OBD-2 scanner (reader, eraser, systems monitor) for about $140 at Autozone.

I just cleared one for a friend with a 2002 RS. He called the dealer and told him that I had a scanner, and the dealer said to do it, since there is no reason to take it in for them to do it.

It was a P0420 on a stock RS.

Given that his only admitted mods are a boost controller and a Vishnu EMI adapter, my bet is on "something else."

Thanks for the help!

After the car sat for about 2+hrs the CEL went away.

Probably 'something else'?

If I pick up a scanner, does someone have a list of OBD-2 codes?

Thanks again,


Drew

Scanners typically come with a list of the generic Type 0 codes, which are the ones you'll commonly see. FYI - I picked up the very nice Equus 3100 ODB II Scanner for $129 at Checker Auto Parts.

You can also look up codes here:

The Actron scanner I have gives the code and an English description of what it is. It does not give diagnostic/repair procedures. Vol 3 (Engine) of the set of Subaru service manuals provides diagnosic tests for each code.

Some things (cat inefficiency, misfire, gas cap loose) can just be erased and then you wait to see if they come back. A blinking cel is very serious.

Erasing cels can put the Inspection/Monitoring systems in a "not ready" condition. It is informative to check those systems after clearing a code. After some time they should set back to "ready" again. The handheld scanner supports those checks too.
