Why is My Warning Light On?

Faulty Oxygen Sensor

The oxygen sensor monitors the engine’s exhaust gas contents and uses that data to control the air fuel mixture. These sensors wear out over time and are typically replaced around the 100K miles or when the engine check light says there is a problem.  

Dirty Mass Air Flow Sensor

This sensor measures all the air coming into your engine.  If it gets contaminated due to a dirty air filter or driving conditions it will not meter the fuel properly.  Without proper fuel metering your engine will be less efficient, use more fuel and have reduced power. A check engine light may result.  

Worn Spark Plugs

Modern spark plugs have a longer service life, but they still wear out and need periodic replacement.  If they become worn or fouled the engine cannot combust the fuel properly and a check engine light may appear.

Loose or Worn Gas Cap

While a relatively simple part, having a loose or worn gas cap can cause the check engine light to come on.  That’s because the fuel system is closely monitored for emission regulations and a defective or loose cap will trigger a light.  It’s a good idea to double check the cap if your check engine light comes on as a simple way to save a trip to the shop.

We use the latest diagnostic equipment to quickly and accurately diagnose your vehicle.  Our ASE-Certified technician will take the time to diagnose the affected system so you can be confident that we are not installing unnecessary parts and that the repair will stand the test of time.
