Why Might Your Car Fail The Test?
Gas Cap – Sometimes a gas cap can crack or simply may have warped and not fit properly any longer and may need to be released. Having gas vapors leak from the gas cap can cause errors that would cause you to fail the emissions test. This is a pretty simple fix. Just go out and buy a 10 dollar gas cap and replace it.
Fuel System – Have deposit buildup in your fuel system can cause increased emissions as well ad reducing your engines performance and contributing to poor fuel economy. You can look into getting an emissions system cleaner to put in your gas tank and run for a week or so to help clean your fuel system which would help with emissions. Just make sure to give it a few days to a week before going in for the emissions test.
Air Injection Readiness – If you have failed the Air Injection readiness test then the first thing to do is to get some fuel additive to add to your gas to ensure the fuel system is clean. Then you will want to drive the car for at least 100 miles before retesting. Be sure to follow the instructions below for the best results.
Begin by: (Make sure you have between 1/4 and 3/4 fuel in the gas tank. The EVAP test will not run while your car has a full tank of gas or the gas tank is near empty) .
– Start the engine. Idle the engine in drive for two and a half minutes with the A/C and rear defroster on.
– Turn the A/C and rear defrost off, and accelerate to 55 mph at half throttle.
– Hold at a steady speed of 55 mph for three minutes.
– Decelerate (coast down) to 20 mph without braking or depressing the clutch.
– Accelerate back to 55 to 60 mph at ¾ throttle.
– Hold at a steady speed of 55 to 60 mph for five minutes.
– Decelerate (coast down) to a stop without braking.
Engine Oil – During the emissions test part of what is being measured is the hydrocarbons in your system. As your oil gets old and dirty it tends to collect more hydrocarbons so it is a good idea to get your oil changed before your emissions testing.
Vaccum Lines EVAP Leak – If your vehicle is producing a gas cap error or EVAP Leak error and you have already replaced the gas cap then you probably have a leak in a vacuum line. The best way to fix this is to have a mechanic do a smoke test to see where the leak is coming from and then replace the tube with the leak.
Ignition Timing – If the ignition timing in your vehicle is off it can cause the emissions test to fail. In order to fix the timing, you will need to have a mechanic correct the timing to the factory requirements.
Catalytic Converter – The catalytic converter works to convert toxic gasses into less toxic ones. If your catalytic converter becomes damaged or faulty it may start putting out more emissions which can cause you to fail the test.
Clearing Codes Before The Emissions Test
If you have a check engine light that has come on but needs to pass the emissions test you may be considering ways to pass the emissions test. If you want to clear the check engine light error codes before your emissions test, your vehicle likely will not pass as the evap monitors will need time to run before the code disappears.
What To Do If Your Emissions Test Fails
If you have failed the emissions test the first thing you need to do is to get a diagnostic test to see what errors come up. You will also want to make sure that you have had a recent oil change and that you have checked for possible EVAP leaks. You can also try adding a fuel additive to your fuel tank and drive the car for 100 miles or so. Then when you have about half a tank of gas go ahead and get retested for emissions.
Drive Cycle Emissions Test
A Drive Cycle test is performed after a repair has been made to the emissions system in a vehicle. It is a test that simulates a test drive of a vehicle that duplicates the scenario of someone starting the vehicle and making a short trip on the highway as if you were driving to work.
Seafoam Before Emissions Test
Some people have asked about using SeaFoam in their gas tank before going for the emissions test. SeaFoam is generally used to clean carbon build up on your cylinders in the engine. It can also be helpful to lubricate cylinders and stabilize your gas but it is not recommended that you use it before your emissions test as it can cause puffs of smoke to come from your exhaust pipe which will automatically fail your emissions test.
How Long Should I Drive My Car Before The Emissions Test?
While there is no testing that has been done to confirm that driving a vehicle on the highway to warm up the engine increases the chance of passing an emissions test. We have heard from some customers that cold starting their engine and going straight to a local testing center caused them to fail the test and when they drove around for a while before coming back the second time with no maintenance changes they then passed the test.
