Yes it can, but it doesn't mean yours will. If your check engine light is on then the car is trying to tell you something is wrong. It turns the light on so you know to go to a mechanic and find out the code which will tell you in a human language what it thinks is wrong. In many newer cars you can find the code out yourself by plugging in a small hand held code reader or even by turn the car of then on three times (without starting it, just move the key to the on position, not start) and the code will display in the dash. Then you just need to Google the make and model and code number to find out what is wrong. So find out what your car is trying to tell you then try to fix that, it will certainly increase your chances of passing emissions.
No, it will not.
If NJ has an emissions standard, no. You'll have to repair whatever is wrong before the vehicle will pass emissions.
No
Whether or not a car will pass inspection with the Check Engine light on is up to the state or county giving the test. As long as the car passes an emissions test, it should be fine.
Yes you can but you won't pass an emissions test and depending what year and make vehicle the check engine light will remain on.
Yes you can but your check engine light will stay on and the truck won't pass emissions tests.
Replace the light bulb.
You can if you want to but the vehicle won't pass emissions and the check engine light will remain on.
You can but the check engine light will remain on and it won't pass an emissions test.
Mileage doesn't matter. As long as it is maintained properly and the check engine light isn't on it will pass emissions.
you need to drive between 40 ti 50 miles to pass emission test , if the light comes back before that , you need to fix your car
No, the check engine light will not shut itself off. It needs to be turned off by a mechanic. If it is on when u go to inspection, your car will not pass The light could go off on its own if the problem fixed itself and there is anough time for it to pass it's selftests enough time. The above answer is incorrect. If the computer in the car does not detect the problem which caused the check engine light to illuminate in the first place after a certain amount of cycles the light will turn off and you will be able to pass emissions. Case in point: My '96 Cougar set the check engine light due to some emissions components failing. Specifically, the purge flow sensor. I replaced the part and did not reset the computer. After about 3 days worth of drive cycles the light turned off by itself.
