my check engine light went on last Friday and went off Tuesday afternoon - I have a car appointment today and don't want to pay the diagnostic fee, but I could get a state inspection since it is up next month - will the state inspection pick up the same stuff that the toyota diagnostic machine would pick up (ex] O2 sensor, gas cap not tight enough, spark plug issues)?

Your state inspection doesn't cover service. So your answer is no. Emissions inspection is different from safety inspection. If your light turned back off you are probably fine. The way that circuit works is it continuously runs a bunch of tests. If a test fails, the light turns on. So if your light went back off, all the tests must have passed. If it were me I wouldn't worry about it. But like the one guy said, check your owner's manual. Maybe it's a reminder of something (I doubt it).

What a lot of people don't know is that cheap gas will make the light come on a lot of the time. The oxyegen levels are lower in cheap gas and the oxyegen sensor picks up on this and reads it as something not working right in yer car, thus bringing on yer light. Keep all yer fluids checked and cganged and do rutine maintenance when required and you'll be fine!

Yes, that works great for me because when my car flunks the emissions, they give me a free print-out of the OBD-II error codes and they don't charge me when I come back for a retest to see if my repairs have fixed the problem yet. And you have plenty of time to get the car emissions retested, so you can sort of use the emissions code reader to help you troubleshoot your car. Even though the check engine light went off, the error codes are still stored in your computer and it takes several "drive cycles" for the stored codes to clear themselves. In fact, sometimes even after you have a sensor error code fixed on your car, you have to wait several days and several trips with your car before you go through enough drive cycles to finally clear the codes and pass the emissions test. Customers complain to their repair shops sometimes that they still can't pass emissions after the shop said they fixed the problem, and the reason is you haven't taken enough trips with your car or gone through enough drive cycles to clear the codes even though the check engine light is off.
However, the Toyota dealer service technician is using a full OBD-II "scanner" with enhanced Toyota specific scanner capability that is much more than a "code reader" only function. So the technician sees a lot more stuff than you see on your emissions error code printout.

No, all they do is safety inspections to see if your car is road worthy.
Some of those "check engine" lights are tied into the odometer. If it went out, it was probably a reminder.
Consult your owners manual to see what they recommend at the odometer reading that you are currently showing.

sorry for most new car IE 2000+ you need to bring it to the dealer or someone with the computer to find out about the engine light but if it turned off then its no problem and if its off now they will not be able to tell you what was wrong

No. The state inspections are for emissions, tires, cracked windshields, wipers, lights, turn signals, etc., not diagnostics. At least, they are in my state.

undo your positive battery cable for about 30 secs, i have found that this at times will reset your car computer.
