Pontiac: 2000 Grand Prix GT

OBD II requires a scan tool. Good ones are very expensive. Cheesedick
scanners can be obtained from Checker, Advance, whoever, for maybe $150.
Most cheap scanners will identify global codes; manufacturer codes must
be looked up in service literature. Good scanners will identify global
and mfgr codes and supply troubleshooting tips.

If a coolant indicator light illuminated, even briefly, the first order
of business is to verify proper coolant level. If the coolant level is
low, the ECT may not supply temp data to the PCM, and the MIL will
illuminate. This is, of course, a possibility, and should not be
construed as a diagnosis.

If you already have a pda you can get a OBDII reader like at
www.auterraweb.com for about 200 bucks.
It will give you codes for everything but abs and airbags. It wont
interact with the car but it will give you readings. It also has
definitions for a majority of P codes. For the rest of the codes I find
the book by Peter David "obd II Diagnostic Fault codes" to be handy.

Have you check your coolant? Not just the overflow bottle!

I made an appointment at the dealer. Hopefully it is very minor. Car runs
great.
