Clearing the Check Engine light does not repair anything - it only turns off the light and clears the error codes. The problem(s) that caused the light to occur are still going to be present and the light will probably come back on, anytime from a few minutes to a few days depending on the problem(s). What you NEED to do is to extract the error codes that come with the light and take the corrective action(s) to repair the deficiencies. That will probably make the vehicle able to pass smog checks. Of course, now that you've cleared the Check Engine light, you've also erased the error codes, so you will need to wait for it to return to get the data you need for repairs.

Why can't I pass smog check engine light won't come on


The smog check requires a visual inspection of your check engine light. It has to come on for a bulb check at startup to make sure it's working. But, the light must go out after starting the engine(it cannot stay on after the engine starts during a smog check). If the check engine light fails either of these two tests, the vehicle will fail the smog check inspection.
You need to have the cause of your inoperative check engine light diagnosed and repaired.

How to reset check engin light


You can do it with a scanner or you can just remove the Negative (-) battery cable for 5 minutes. Be advised if you are doing this to pass a smog test they will know the system has been cleared and fail the test.

No any codes will let you fail..Rangers are bad about the valve sticking..But first look on th driverside very back on the intake..Youll see a valve with two vacuum lines The one that goes on the bottom of the valve makes a 90 bend and is bad about breaking..If the lines are good then work the valve by hand and see if it will move

My CE light is on. The code is PO420. It is a 2002 Corolla. Smog is due. Two years ago, the same thing happened. I bought a scanner, cleared the light. Took it to smog. Passed. But this year, I cleared...


The P0420 is for the catalyric converter, you'll have to have it replaced. It will fail the test as long as the light is on. Clearing the code information also clears the monitor infor, to pass the monitors required you'll have to put some miles on it in both city and highway driving, not all monitors may be required so check with your local smog station which ones have to pass.

Keeps failing emission check engine light not on


As you probably know by now there is no way to pass an emissions test as long as the check engine light is on....Your car is what they call an OBD2 system... You need to have the diagnostics codes pulled by a special tester specifically for OBD 2 systems... Once codes are pulled fix if necessary any problem and have the codes cleared... This will turn the check engine light off an enable you to pass smog providing your car is running properly...
