Check Engine Light Service 2015 Jaguar XJ

What do you do when you’re driving along in your Jaguar XJ and suddenly, a yellow light lights up on your dash and says "Check Engine". If you’re like most Jaguar owners, your heart sinks a bit because you have tiny idea about what that light is trying to tell you or how you should react. The fear of the unknown (or the cost of the unknown) can be just as stressful. But take a deep breath and realize the light coming on doesn’t indicate 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 2015 Jaguar XJ checked as soon as capability. Ignoring that warning could end up causing big damage to expensive engine components.

When your 2015 Jaguar XJ's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t reasonable, a computer turns on your check engine light. This amber or yellow light is commonly 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 diagnose tool that is used by our Jaguar auto repair mechanics at Jaguar of Greenville. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you determine that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced expert to mean the issue and repair it.

How many miles can you drive with the check engine light?

Since all check engine code has its own level of severity, it is difficult to predict how frequent miles you can travel to work with the warning light on. It could be anything from a bad sensor to plug wires needing to be replaced. If you check engine light is flashing, we recommend that you pull over and contact Jaguar of Greenville to help express if your vehicle is safe to travel to work in or if we recommend a tow truck.

For example, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will turn itself off. Likewise, if your catalytic converter is going factual, and you did bountiful 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 2015 Jaguar XJ light will go off after about 20-40 miles. If you drive over that amount and the light is still on, you will need to bring it in to Jaguar of Greenville so the light and code can be double-checked and reset.

What could cause the check engine light to come on in a 2015 Jaguar XJ?

When your check engine light comes on, this could be as pure as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a alarming problem that could cause alarming wear and tear to your engine and come with a extraordinary repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow generally means something less alarming but a flashing check engine light indicates that your vehicle’s engine is in alarming trouble and service is necessary immediately. If your check engine light is flashing in your 2015 Jaguar XJ, we highly advocate not to drive the vehicle and schedule Jaguar service today. Below is a list of the most correct reasons your check engine light can come on:

  • Issues with any aftermarket items. An aftermarket alarm, exhaust or added item can wreak havoc on your 2015 Jaguar XJ if it’s not installed perfectly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even avert the vehicle from starting. If these issues sound prevalent, bring your XJ to Jaguar and have our team of certified mechanics ensure that your aftermarket items were installed properly and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might estimate a microscopic bit more but could save you money from having to get poor work and break caused by poor installation work corrected.
  • Your catalytic converter is harmful or going harmful. The catalytic converter is a part of your 2015 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 usually 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 2015 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 added problems from overheating.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, commonplace as the O2 sensor, measures the sum of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be fewer competent 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 break to your catalytic converter and your 2015 Jaguar XJ's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to indicate the justifiable mixture of air and fuel that enters the cylinders in your engine. A harmful O2 sensor can also cause a car to fail an emissions test.
  • One of the most commonplace and copious cause is that your 2015 Jaguar XJ gas cap is loose, damaged or missing. The gas cap for your 2015 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 harmful fuel cap? If your gas cap is aged 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 immediately after you put gas in your 2015 Jaguar XJ, first thing you should check is to make sure 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 sum of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to definite changes, like altitude. If your Jaguar XJ is having trouble starting, idling rough or has a sudden change in the position of the throttle pedal, this could be a sign of a harmful mass airflow sensor.
  • The battery is low or dead. The battery in your 2015 Jaguar XJ is every conclusive. 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 a few decades ago, and they don't really require maintenance. The rate of a new one depends on the type of Jaguar you drive, but check our existing service coupons and specials.
  • New Spark Plugs or Plug Wires are needed for your 2015 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 bring the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are harmful or aged, 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 break to ignition coils and O2 sensors, first-rate to more expensive repairs.
  • Your 2015 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 cut down 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 bare out and crack, especially if they’re exposed to important heat or extreme congenial.
