Why is My Check Engine Light On?

There are many potential causes of a check engine light on your vehicle’s dash. It’s important to bring your car in for a comprehensive check engine diagnostic test sooner than later, especially if the light is flashing. Here are some reasons your check engine light may be on:

• Broken Gas Cap: Something as small as a broken gas cap can trigger your car’s check engine light. If the cap isn’t sealed properly or is damaged, it can lead to dangerous vapor leaks which affects your vehicle’s overall fuel efficiency.
• Faulty Catalytic Converter: Are you noticing a sluggish engine or poor fuel efficiency? It could be a bad catalytic converter. Stop by Tanner Motors for trusted check engine light diagnostics in Phoenix, AZ!
• Oxygen Sensor (O2 Sensor): Your car’s O2 Sensor helps measure the unburned oxygen in the vehicle’s exhaust. This helps maintain proper fuel mixture and emissions. If it fails, it causes subpar fuel economy and poor engine performance.
• Failing Mass Airflow Sensor: This sensor regulates the amount of air allowed to enter the engine. A failing mass airflow sensor leads to rough idling, slow acceleration, and reduced fuel efficiency.
• Old Spark Plugs and Wiring: It is essential to replace spark plugs and wiring regularly to avoid engine misfires, rough idling, and overall bad engine performance. Book a check engine light diagnostic with Phoenix’s best mechanics today!
