Here is what they check when you bring your car in for a E-Test.
If the inspector finds any of the following issues, it must be corrected before the emissions test can continue, as it could lead to injury and/or the test equipment may not work properly:
- missing catalytic converter and/or gas cap
- defects in the fuel filler pipe
- problems with the on-board computer system that would prevent the vehicle from being tested
- visible smoke coming from the tailpipe
- any problems the inspector believes would prevent the vehicle from being tested safely
You will receive a pre-test check rejection form, if the vehicle cannot be tested. You will need to return for the test, once any required repairs are made.
The actual test entails
Hooking up device monitor to check if there are any codes reading pertaining to the emissions, you car will fail your e-test if that check engine light is on.
Then they hook up the tail pipe test to see if there is any leaks with your exhaust that could be dangerous to the public and environment.
What they don’t want you to know
If your car is over 20 years old and your repair to get the test is over 300$ you could be lucky enough to get a conditional pass on your vehicle. They can give you, your slip with the information that its a conditional and you can get this years sticker.
