What could cause the check engine light to come on in a 2012 Jaguar XJ?

When your check engine light comes on, this could be as plain as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a precarious problem that could cause precarious damage to your engine and come with a substantial repair bill. Depending on your make and model, the check engine light will illuminate or blink. A consistent glow mostly means something less precarious but a flashing check engine light hints that your vehicle’s engine is in precarious trouble and service is decisive rapidly. If your check engine light is flashing in your 2012 Jaguar XJ, we particularly advise not to commute the vehicle and schedule Jaguar service today. Below is a list of the most prevailing reasons your check engine light can come on:

  • Your 2012 Jaguar XJ has a vacuum leak. Every Jaguar XJ has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower harmful emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can dry out and crack, especially if they’re exposed to imposing heat or extreme bleak.
  • New Spark Plugs or Plug Wires are needed for your 2012 Jaguar XJ. The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or old, you will experience poor performance and reduced power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or damage to ignition coils and O2 sensors, best to more expensive repairs.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, established as the O2 sensor, measures the amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be fewer productive when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A faulty sensor can not only affect your miles per gallon, but it can cause damage to your catalytic converter and your 2012 Jaguar XJ's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to mean the right mixture of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a car to fail an emissions test.
  • The battery is scanty or dead. The battery in your 2012 Jaguar XJ is every rare. Without a car battery, your car won’t start, light up the road ahead, play the radio or charge your phone. Today’s car batteries last much longer than they did some decades ago, and they don't really require maintenance. The value of a new one depends on the type of Jaguar you drive, but check our current service coupons and specials.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2012 Jaguar XJ’s exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is frequently caused by neglected maintenance, which is why Jaguar of Greenville offers a complimentary multi-point inspection with every Jaguar service. If you have an issue with your catalytic converter and don't get it repaired, your 2012 Jaguar XJ will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your car may run at a higher temperature, too, which can cause other problems from overheating.
  • Issues with all aftermarket items. An aftermarket alarm, exhaust or other item can wreak havoc on your 2012 Jaguar XJ if it’s not installed correctly. These aftermarket parts and accessories can discharge the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound accepted, deliver your XJ to Jaguar and have our company of certified mechanics ensure that your aftermarket items were installed accurately and aren't causing all issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might cost a scant bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • One of the most accepted and copious cause is that your 2012 Jaguar XJ gas cap is loose, damaged or missing. The gas cap for your 2012 Jaguar XJ serves multiple purposes. It prevents gas fumes from being released when you aren't driving, it seals the fuel system and helps maintain pressure within the fuel tank. What happens if you have a bad fuel cap? If your gas cap is old or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump. Luckily, to replace a gas cap isn't expensive. If your check engine light turns on shortly after you put gas in your 2012 Jaguar XJ, first thing you should check is to make bold the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Jaguar XJ is what determines how much fuel is needed to run your engine efficiently by measuring the amount of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to genuine changes, like altitude. If your Jaguar XJ is having trouble starting, idling rough or has a speedy change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.

However, that is the limitation of the Check Engine Light – it won’t tell you what specifically is awry nor what to do about it.

Check Engine Light Service 2012 Jaguar XJ

What do you do when you’re driving along in your Jaguar XJ and swiftly, a yellow light flashes on your dash and says "Check Engine". If you’re like most Jaguar owners, your heart sinks a few because you have little idea about what that light is trying to tell you or how you should react. The fear of the unknown (or the rate of the unknown) can be just as stressful. But take a deep breath and realize the light coming on doesn’t mean you have to pull the car over to the side of the road and call a tow truck, but it is recommended that you get your 2012 Jaguar XJ checked as soon as attainable. Ignoring that warning could end up causing major damage to pricey engine parts.

When your 2012 Jaguar XJ's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electrical control system that it can’t correct, a computer turns on your check engine light. This amber or yellow light is ordinarily labeled “check engine” or “service engine soon”, or the light may be nothing more than a picture of an engine, or a picture of the engine with the word “check.”

When the light turns on, the ECM stores an engine code or “trouble code” in its memory that identifies as the issue, whether it's a sensor or a failing engine part. This code is read with an electronic scan tool that is used by our Jaguar auto repair technicians at Jaguar of Greenville. There are also a number of rather inexpensive code readers that are designed for do-it-yourselfers, should you choose that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an professional professional to favor the issue and repair it.

Likewise, if your catalytic converter is going functional, and you did a lot of stop-and-go driving, that may have turned on the check engine light due to the high usage of the converter. In most cases, your 2012 Jaguar XJ light will go off after about 20-40 miles.
