Check engine light just came on in a 1999 mazda protege. Can I check the codes to try to figure out what the problem is?

I used to have a Protege. The check-engine light was the only thing NOT to go wrong with it. Then I plastered it on a concrete divider, after getting into a heated argument with a fridge door.
I'll check my Haynes for my old Protege, but I think it might only go to 97. Nevertheless, I'll look.

99% of newer cars can't have the codes pulled without a scan tool. You're best off finding a friend who has a scan tool if you're hurting for cash, but if nobody has a scan tool, you're just going to have to get it fixed at a shop or pay the fee to get the codes pulled. Most shops charge about 50-75 bucks to pull codes and reset them.

Oh, another cheap alternative is to see if the Autozone (or whatever) has one of the scanners made for one vehicle make. Usually they have all the GM and Ford vehicles, but it's hard to say if they'll have a Mazda code checker.

Good luck...you're probably just going to have to bite the bullet and take it to a shop.

1) Have you installed any aftermarket stuff (ie; intake) ? If so, uninstall and see if it stops. "Odd" MFA readings can cause this. Generally, the car will "learn" the new settings, adjust timing and fuel (if so-equipped) and go-on with life w/out the code.

2) Make sure your gas cap is tight (this is the MAIN cause of OBD2 MILs or check engine lights.)

Good luck!

Yeah, my book only went to 97. However, it is stated that all the ODB-II systems do not output to the "Check Engine" light. Rather, they do need a scantool to do this. Sorry.
