Every year, most cars are required to pass an emission test to renew their vehicles registration and keep their car or truck on the road. Emission tests are designed to ensure that your vehicle isn’t pouring out more pollutant emissions than it should be. While many people pass with no problem, there are years that a vehicle fails the test. Should this happen, we can diagnose the issue and get you back on the road with our auto repair services. Below are some of the common emission issues we can prevent with an emission inspection, or repair after your emission test.

O2 Sensors
Your vehicle’s oxygen sensor is used to measure the amount of oxygen present in the exhaust. A defective O2 sensor can lead to vehicle overheating, higher emissions, and a loss of power during acceleration. We can diagnose and replace your oxygen sensor, typically while you wait.

Vacuum Leaks
A vacuum leak is typically caused by a faulty MAP sensor. Leaks can also be found in cracked or improperly sealed gaskets or vacuum lines. We can find the leaks in your vacuum system and ensure that your MAP sensor is working properly.

Ignition System
During your emission test a hydrocarbon test will be performed, ensuring that your vehicle is not releasing excessive hydrocarbons. One of the leading causes of failing a hydrocarbon test is the vehicle’s ignition system, including spark plug wires, spark plugs, faulty ignition timing, or old distributor caps.
