Issues that Can Cause Your Vehicle to Fail a Smog Check
If your vehicle fails to pass a smog check, you will need to make repairs that will allow it to pass the test. Sornoso Automotive Repair is a full-service repair shop. We service all makes and models of foreign and domestic vehicles, and can often repair your vehicle quickly, so you can continue with your smog check.
Some of the most common reasons that your car may fail a smog check include:
Problems with your vehicle’s oxygen sensor
Your car’s check engine light is on
Your vehicle’s air filters need to be replaced
Your spark plugs are malfunctioning
Your vehicle has a fuel injector leak
Your gas cap does not fit properly or is damaged
Your catalytic converter is faulty
The EVAP system is malfunctioning
Major engine problems
In some cases, the problem can be solved immediately. For example, in some vehicles failing to close the gas cap all the way will prompt the check engine light to come on. If this is the case, the computer simply needs to be reset. In other cases, a recently changed battery or jumpstarted battery may cause the check engine light to come on. In other cases, something as simple as having the air filters replaced, can resolve the problem.
If your vehicle is relatively new, and you take diligent care to have regular service, including oil changes, your car will likely pass the smog check. But if your check engine light is on, you should not take your vehicle for the test, as the light automatically fails the car.
Instead, bring your car to Sornoso Automotive repair for fast and accurate diagnostic testing. Once we determine the cause of the check engine light, you’ll be provided with an accurate estimate and timeline for repairs. Many repairs can be made the same day.
