Learn How to Reset a Check Engine Light

No one wants to see their check engine light come on while they’re driving through Jersey City or Fort Lee. For some drivers, checking the gas cap or taking care of the problem at home is quicker and easier than scheduling a service appointment. Still, you might wonder what happens if your check engine light doesn’t go off automatically. If you don’t mind getting under the hood, it’s easy to learn how to reset a check engine light at home.

Always Check Your Gas Cap

You might be surprised to learn that something as simple as an unscrewed gas cap can cause a check engine light to turn on—but it’s true! In these cases, the light comes on because the sensor can detect the presence of gasoline fumes.

If adjusting the fuel cap doesn’t solve the problem, it’s likely that fumes are coming from another part of your vehicle, or that another component is causing a real issue. In either case, the check engine light isn’t a warning that you’ll want to ignore for long.

Should You Reset Your Check Engine Light at Home?

Before we go any further, we think it’s important to point out that your Jaguar check engine light won’t just come on by accident. Although some potential causes are quick and easy to fix, you should only reset your check engine light yourself if you know what caused the problem—and you’re certain that you fixed it. It’s unwise to reset a check engine light at home unless you’re absolutely certain that the underlying issue has been addressed.

If you do perform a manual reset, and your check engine light still comes on after you start driving, make sure to schedule service and have the issue resolved by an expert at our Paramus service department.

How to Reset a Check Engine Light by Disconnecting Your Battery

The easiest way to reset a check engine light is to disconnect the negative (black/-) battery cable and hold it to the side for 30 to 60 seconds. This will allow your internal diagnostics systems to reset.

If you’ve never disconnected your battery before, we’re happy to report that you only need a few easy-to-use tools. Grab safety glasses, a pair of gloves, and a wrench. You’re ready to get started:

1. Put on your safety glasses and electricity-safe gloves.
2. Turn your engine off, apply the parking brake, and open the hood.
3. Locate your Jaguar vehicle’s negative battery terminal. Loosen the cable with a wrench, and pull it off.
4. Keep the cable in your hand for a minute or more, and then reconnect it with your wrench.
