Emission Repair

Every year, most cars are required to pass an emissions test to renew their vehicle’s registration, allowing the car or truck to operate on the road. Emissions tests are designed to ensure that your vehicle is running clean and that the level of pollutants it emits is well within defined limits. While many people pass with no problem, there are years when a vehicle that has previously passed may fail the test. Should this happen, we can diagnose the issue and get you back on the road with our reliable auto repair services. Below are some of the common issues we can prevent with an emission inspection, plus the car repairs we can handle for you after an 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 emissions test, a hydrocarbon test will be performed, ensuring that your vehicle is not releasing an excessive level of  hydrocarbons. One of the leading causes of failing a hydrocarbon test is a problem with the vehicle’s ignition system, including spark plug wires, spark plugs, faulty ignition timing, or old distributor caps.
