Why Is My Check Engine Light On?
Your Jaguar is designed to signify when something may be amiss. It does this in the form of dashboard warning lights, like the check engine light.
You may be driving around Albuquerque, Rio Rancho, or South Valley and notice that the check engine light is on. There are several reasons why that could be, which we’ll cover below.
Read through our informative guide, then contact Jaguar Albuquerque to schedule a service appointment.
1. The Gas Cap Is Loose or Missing.
The check engine light could be coming on simply because your vehicle’s gas cap is loose or missing completely. The gas cap is what seals the fuel system and helps keep pressure within the tank. Plus, it helps prevent gas fumes from being released into the atmosphere.
If you continue to drive without a gas cap, you may lose fuel through evaporation. The result would be needing to make more trips to the gas station to refuel.
2. The Oxygen Sensor Has to Be Replaced.
The oxygen (O2) sensor is what measures the amount of unburned oxygen in a Jaguar vehicle’s exhaust system.
If you don’t get this part replaced, the engine may burn more fuel. If this happens, you’d lose fuel economy, getting fewer miles per gallon. Plus, a faulty sensor could damage the catalytic converter and/or spark plugs.
3. The Catalytic Converter Is Bad.
A catalytic converter does what the name states: converting carbon monoxide into carbon dioxide. This helps emit fewer pollutants, which better protects the environment.
By not replacing this part when needed, your Jaguar may run at a higher temperature than normal, which could be dangerous. You may also experience reduced performance, along with a decrease in fuel economy.
4. The Car Needs New Spark Plugs.
The spark plugs are what ignite an air/fuel mixture inside the combustion chamber of your Jaguar. As with the other parts, not replacing this one when necessary can cause poor performance, in addition to reduced fuel economy.
Furthermore, leaving damaged spark plugs inside the vehicle could cause the catalytic converter to clog or the oxygen sensor to stop working. That’s why it’s crucial to get new spark plugs the moment they’re needed.

What to Do If the Light Comes On
If the check engine light appears on the dashboard, there are several steps you could take. First, you’ll want to go ahead and check to see if the gas cap is loose. If it is, tightening it may often solve the problem.
If the light is blinking, or you notice a loss in power, try to reduce your speed while driving. You could also reduce the car’s load—say, by no longer towing a trailer until the issue gets resolved.
Finally, you could open the car’s hood and check for any issues. Look for any possible hoses that are leaking or wires that may be frayed. Take a look at the spark plugs, too. If they’re cracked or show any signs of wear and tear, then they may be misfiring. In that case, you’d want to replace the old wires as soon as possible.
