Engine light alarm,did not pass smog? - XL7 Suzuki Cars & Trucks

It won't pass smog in California because the 1st thing a smog tech does it check for fault codes on the vehicle's computer with a scanner.

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.

run the fault codes to ensure that the EGR valve is faulty. Engine lights to not always come on unless there is something drastic going on with the engine /gearbox so that you can stop the car before damage is done.

making the light go out will not enable the car to pass smog! it is indicating a problem and this problem will surface when it is checked at smog inspection.

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

Smog is what comes out of the tail pipe. Have the engine checked out as to why the light is on, and have it fixed. .

if the light went out on it's own ,,,yes it should now pass inspection

If your 84 mustang is fuel injected, it has a check engine light. If it is carbeurated (like mine) it does not. 85 and up are EFI, 84 was the crossover year.

Try this:-
Theres a vaccum pipe tht fits on the brakes booster just under the mastercylinder probabely it may have popped out or the sensor could be faulty ....worth a try ;)

i really cant tell you if it will pass the smog test or not because the check engine light could be on because of a faulty Catalytic converter
