One common problem with a check engine light is that its a bad or loose gas cap try replaceing that or make sure its sealing tight. If its not that then I supose you could depending on the make and year remove the dash cover and disconnect the led to the check engine light light.

however in some cars this may afect the computer. if its an older style one that has a light bulb behind it simpley take the bulb out or disconnect the wires and reconnect them later. Like I said depending on the year it can be 100% ok or may cause problems. I would disconnect it drive the car for a bit and if you notice no problems get it inspected the reconnect later.

THEN fix the problem thats causeing the light to come on.

I tend to avoid dealers like the plauge they over charge you for everything and for the most part are a rip off. like $100 to change spark plugs. Get MOPAR parts but do it yourself. The dealer shop is evil I tell you evil......

oh Im rambleing

Except if the shop is doing the inspection right, they will turn the key to the run position without starting to check for the lights to come on. If they don't see all the lights, they know it's either burnt out or removed - then they inform you after-the-fact that they just put a rejection sticker on your car.

Try turning the ignition on and off 3 times to see if there are any codes; otherwise, when you disconnect the battery to reset it make sure you leave it disconnected long enough. I have had to leave mine disconnected for several minutes for it to reset.

One other thing to note is that in many states, if you just disconnect the battery to clear the code, the car STILL won't pass inspection. When they hook up the scanner, the OBD diagnostics will report that it has been reset and has not had enough operating hours to evaluate the engine and emissions. That's an automatic fail, and you'll be told to come back after the car's been running for a bit longer. Of course, if the problem that threw the Check Engine Light on hasn't been fixed, then by the time the car is ready to be inspected, your light will be on again.

The inspections are done for a reason. If there's a problem, then fix it! Then your car should pass.

Around here, they don't even bother looking at the light. The inspector just plugs the inspection computer into your car's OBD II jack. Any codes are downloaded, and if the car isn't ready to be tested (e.g. you just disconnected the battery and not enough drive cycles have elapsed since), you will have to come back later to complete the test. The test report includes any trouble codes that have been set which are relevant to emissions. This is the case for vehicles 'model years 94 or '96 and later. Earlier vehicles get the standard tailpipe + dyno test at various power settings.

If the light is on, there must be a code set. Find out what that code is, and find out what needs to be done to fix it. If you're stuck, post the code here. It might be a loose gas cap, it might be a simple oxygen sensor, it might be a misfiring spark plug. Who knows until you get the code. Your car will be better off if the problem can be resolved, regardless of the emissions test. If you need help getting the code, post your vehicle model and year here. Certain vehicles can display the code to you on their own, and some stores, such as Autozone will obtain your diagnostic codes for no charge.

Hope this helps.
