Check Engine Light Repair in Johnson City
Ponder Auto Repair Johnson City TN
If your check engine light comes on, there's probably no reason to panic. But it's still important to bring your vehicle to Ponder Auto Care in Johnson City right away. Putting off check engine light repair could quickly allow a small problem to turn into a major issue that will likely be expensive to fix.
So, what the heck is going on with your car? Before giving in to the panic that comes with the prospect of costly check engine light repair, see if your gas cap is on correctly. Even something as simple as not tightening your cap after filling up with gas can cause the light to come on.
If your gas cap isn't the issue, here are common problems that a check engine light might indicate:
- Spark Plugs & Wires – Designed to ignite the air/fuel mixture that powers your car, bad plugs or wires cause poor engine performance, reduced power and lower MPGs. If ignored, problems can spread to the ignition coils, O2 sensors and other parts.
- Oxygen Sensor – The O2 sensor measures unburned oxygen in your exhaust. A bad sensor can cause your engine to use excess fuel and reduce fuel economy by up to 40%, as well as cause expensive damage to your catalytic converter.
- Catalytic Converter – Your cat turns engine pollutants into less harmful gases that exit through the muffler. If check engine light repair isn't completed, performance will be drastically reduced and the vehicle won't pass emissions testing.
- Mass Airflow Sensor (MAF) – This component measures the amount of air entering the engine to determine the proper air/fuel mixture. A bad MAF will affect performance and fuel economy, even damage the O2 sensors and catalytic converter.
