What Does That Check Engine Light Really Mean This Fall?

As the temperature shifts in Middle Tennessee, it’s common for the Check Engine light to pop up on your dashboard. Seasonal temperature drops affect tire pressure, oxygen sensors, and fuel system vapor pressures.

While a loose gas cap can sometimes trigger the light, it can also point to issues with your catalytic converter, ignition coils, or mass air flow sensor.

Ignoring it can lead to worse fuel economy and bigger repairs down the line. If your light comes on, swing by Reliable Automotive in Franklin for an accurate, honest diagnostic check.
