Just like other cars, the Jaguar is designed to give you an alert in the form of warning lights when there is something wrong. The check engine light is one of them. If you find that this light is on, there could be many reasons. Given below is a description of some of the common reasons.
1. The Gas Cap Is Missing or Loose
First, you should check to find out if the gas cap is there. If it is not missing, check to make sure it’s not loose. The function of the gas cap is to seal the fuel system and maintain the required pressure in the tank. Apart from this, it keeps the gas fumes from polluting the atmosphere.
If the gas cap is loose, fuel will continue to evaporate. As a result, you will have to spend more money on refueling gas.
2. Faulty Oxygen Sensor
This sensor measures how much of unburned gas is there in the exhaust system of the vehicle. If this sensor is faulty, it may cause significant damage to the catalytic converter and spark plugs.
3. Faulty Catalytic Converter
This component converts carbon monoxide into carbon dioxide. The idea is to reduce the amount of pollutants and protect the environment. When this component doesn’t work properly, the check light turns on.
It’s better that you replace this part or your vehicle engine may heat up. As a result, the performance and fuel economy of your Jaguar will go down.
4. The Spark Plugs need to be replaced
Spark plugs of a car ignite the mixture of air and fuel in your Jaguar’s combustion chamber. Just like other parts, if you don’t replace the spark plugs, you may experience poor performance and low fuel economy. The check engine turns on when the spark plugs need to be replaced.
What should you do?
Now, if the check engine light turns on while you are driving, you can take a few steps. First, you should check the gas cap to ensure it’s not loose. But if the light appears to be blinking or there is a loss of power, reduce your speed. Besides, you should try reducing the load on your car by separating the trailer. Once the issue is fixed, you can attach the trailer again.
Lastly, you can open the hood of your car and check for any issues. Check to make sure no hose is leaking or no wire is frayed. If the spark plugs show some signs of wear and tear, chances are that they are misfiring. The fix is to replace the wires right away.
In short, if the check engine light comes on, don’t take the risk of ignoring it. We suggest that you take your vehicle to a repair professional as soon as you can.
