Learn How to Reset a Check Engine Light

Knowing how to reset your check engine light can mean the difference between a stressful morning or a carefree commute through Pleasanton. If this warning light won’t turn off even after addressing the issue that activated it, the service experts at Lexus of Pleasanton have the service tips you need to reset a check engine light.

First, Resolve the Issue at Hand

When your check engine light illuminates in Fremont, it usually means that something within your vehicle needs attention. While sometimes the problem can be as simple as a loose gas cap, it could also be a larger issue under the hood. It’s always best to determine what’s going on and fix the problem, but if you’re not sure what’s wrong, you can bring your vehicle by the service center at Lexus of Pleasanton, where our certified technicians can do a quick inspection and resolve the issue.

Perform a Manual Reset for Check Engine Light

If you’ve addressed the problem but your warning light won’t turn off, you may need to manually reset your check engine light. Follow these steps:

  1. Turn off the ignition and put on safety glasses and gloves.
  2. Locate the negative battery terminal. Usually, it has a black cap and a negative (–) symbol. For reference, the positive cap is red and will have a positive (+) symbol.
  3. Loosen the nut on the negative terminal with a wrench, then pull the negative connector from the battery. Keep it to the side for 30 – 60 seconds.
  4. Reconnect the negative cable and tighten it back up with your wrench.

If this doesn’t work, there is one more trick you can try in Dublin.

Check Your Gas Cap

Your check engine light may turn on because your gas cap is loose. A loose or cracked gas cap can release fumes as you’re driving in Livermore, which can trigger the engine light. To prevent this problem, simply remove your gas cap completely and screw it back on tight. If your check engine light still won’t turn off, it’s time to schedule service.
