In California, if your car can’t pass a smog check, you have to get it repaired and then try again. If the problem still doesn’t go away after two tries, you might be required to pay for an emissions test. You do not need to worry about this law; the DMV will contact you if your car needs repairs or an emissions test.

What Are The Most Common Reasons For A Failed Smog Check?

  • Leaking Fuel Injectors

During the smog check, if your car is consuming too much fuel to run properly then it’s likely you’ll fail this test. Leaking injectors or a malfunctioning Mass Air Flow sensor will cause an excess of carbon monoxide in regards to how often these two things need checking out for various reasons like that; all combined can result in one thing-a failed emissions inspection!

  • Fuel Metering Malfunction

There’s a little-known mechanism that checks the air/fuel mixture used by an engine to make sure everything operates smoothly. This monitoring is essential for ensuring smog check success, as it will detect any problems with either your electronic control unit or fuel injection system if they were broken in some way!

  • Broken Oxygen Sensor

An oxygen sensor that is dirty, failing, or damaged cannot monitor the exhaust to provide a proper air-to-fuel ratio. This can cause issues including reduced engine power and overheating which may lead you to have an increase in emissions production at inspection time along with other side effects such as jerking while accelerating because of decreased efficiency caused by smog interference.

  • EVAP System Fail

The Evaporative Emission Control System or EVAP for short is a system that detects gasoline vapors evaporating from the filling hose. If it malfunctions your fuel economy will suffer significantly! The device keeps fumes from raw gasoline being released into the environment. More testing may be done to see if this issue is with a vacuum hose, vent, or somewhere else.

A test-only facility will provide you with a report detailing the reasons for your failure. A repair shop can also help prepare vehicles to pass their own retests, so don’t put off repairs since this could make it difficult or impossible to get registration stickers from DMV until they are cleared by smog testing!
