How to Reset Check Engine Light

Acura TLX interior

Any new vehicle will include a check engine light, one of the most valuable tools for alerting you when a problem is occurring in your vehicle. But sometimes even after you fix the problem at a service center, there can be an issue with the light staying on. In a lot of cases, fixing this is as easy as checking that your gas cap is tight, though occasionally more elaborate fixes are required. Fresno Acura covers how to reset check engine lights in most vehicles and other tips below!

How to Reset Check Engine Light After Service

So, you’ve solved your engine problems but there’s still a check engine light on. What’s a Clovis driver to do? You’ll have to access the car battery to solve this common issue, but it’s not too difficult if you’re wearing safety gloves and safety glasses:

  • Let the Car Cool: You’ll be accessing the battery, so turn off the ignition and let things cool down.
  • Find the Negative Terminal: Your car battery has a negative terminal that is usually indicated by a (-) sign, as opposed to a (+) sign.
  • Remove the Negative Connector: You’ll need to loosen the negative nut before you remove the negative connector.
  • Wait, then Reconnect: Wait 30-60 seconds with the connector out then place it back in, securing the nut in the battery.

And now you know how to reset check engine lights!

Checking Your Gas Cap

Another hack some Madera drivers know for how to reset check engine lights involves the gas cap. If your gas cap isn’t screwed on correctly or if it’s missing, this triggers the check engine light. Luckily, this is a quick fix, so check your gas cap first!

Reset Check Engine Light: Engine Issues

So, what does your engine light indicate if it comes on in Visalia? There are many reasons you’ll want to come to a service department, as the engine signals a few problems:

  • Low/Empty Fuel Tank

  • Emission Control System Issues

Other lights like the tire pressure light tell drivers when their vehicle is experiencing issues they’ll need to fix before more serious problems occur.
