5 Tips On How to Pass Your Emissions Test

Passing your smog test doesn't require any rocket science. If you take proper care of your car, you shouldn't have to worry about failing at all. Your vehicle needs to be within the "normal range" of emissions determined by the government to pass the test.

Once you get a renewal notice from California's DMV, you should make an appointment with a licensed station, mark your calendar, and start "studying"/preparing your vehicle for the test. Here are some of our top tips on how to pass your smog test!

Perform Regular Maintenance

Maintenance is key to pass the smog check with stripes and stars. You should get all your maintenance tasks, including oil changes and spark plug replacements, beforehand. Renewing your fuel injectors can also benefit you by ridding of carbon deposits and lessening emissions. 

Make Sure Your Tires Are Properly Inflated

The more air you put in your tires, the less stress you put on the engine, making it burn less. Please ensure that the air pressure is within the manufacturer's given range.

Fix Check Engine Light

If your check engine light is on, please have it fixed before your smog check appointment. Otherwise, a check engine light will fail you immediately. To understand what is making your check engine light come on, please reach out to a professional for assistance. 

Warm Up Your Car Before Test

The warmer your car engine is, the fewer hydrocarbons will make it out of the tailpipe. If you want to pass quickly, have your emissions tested on a relatively cool day while still ensuring your engine is hot as possible. To warm up your car, just make sure you've been driving around for at least 15 minutes before the test takes place.
