The emissions part of your state inspection failed What is the most common cause?
Most common? Probably the oxygen sensor.
But that's like asking your doctor, "what's the most common cause of a bellyache?" Usually it's gas but if it isn't, then what.
Don't guess. Find out what failed the test, look at the sheet that they gave you, it usually has a reason for the failure.
You don't give any clues, so I don't know the year of the vehicle, but if it's EFI you can connect an automotive code scanner to find out what the computer has to say on the subject. That's actually your best first step.
You can borrow, rent or buy a code scanner at most auto parts retailers.
What else can I help you with?
Can an oxygen sensor cause a failed emissions test?
only in California
Will a knock sensor code fail a nys inspection?
That will cause you to fail an emissions inspection. Anything which triggers the CEL will, because everything which triggers it will adversely impact the emissions system on that vehicle.
How can you make the exhaust sound deeper at home without buying anything?
Punch a hole in the muffler. (May cause you to fail a safety/emissions inspection) Ha ha.
What is the problem if a 96' Saturn SL1 has power fluctuations making the on-board computer reset and cause a failed inspection?
Bad Engine Coolant Temperature SEnsor.
What causes a PT cruiser fog lights to remain on?

What can cause an emissions leak on a 2001 Chrysler Town and Country?
The most common leaks are cracked vapor hoses and a loose gas cap.
Will a broken motor mount fail a NYS inspection?
Yes, a broken motor mount can cause a vehicle to fail a New York State inspection. Motor mounts are essential for securing the engine and reducing vibrations; if they are damaged, it can lead to misalignment and other issues. Inspectors may also assess the safety and performance implications of a broken mount, which could result in a failed inspection.
O2 sensor can cause high Nox?
Nox is The abbreviation of Oxide(s) of Nitrogen. These are only produced at high burn temperature's. In a modern engine excess Nox emissions can be caused by a lean fuel mixture caused by a failed O2 sensor(s) Or A failed or pluged EGR valve
Why does the heater fan only work on the high position on a 2001 Chrysler Sebring?
The most common cause is a failed blower motor resistor.
Can loose gas cap affect emissions test?
Yes, a loose gas cap can affect an emissions test. A loose or damaged cap can cause fuel vapors to escape, leading to an increase in hydrocarbon emissions, which may result in a failed test. Additionally, the vehicle's onboard diagnostic system may detect the issue and trigger a check engine light, further complicating the emissions testing process. It's important to ensure the gas cap is secure before an emissions test to avoid potential problems.
