Land Rover Range Rover Check Engine Light Codes
The check engine light turning on can be quite intimidating to see that little light on your vehicle’s dashboard suddenly illuminates, but in reality, it is not something that should cause you to shut down in fear right away. If you hear the term, diagnostic trouble codes (DTC), these are just another name for check engine light codes. These are automotive computer codes stored by the ECM, also known as the OBD (on-board computer diagnostic system) in your Range Rover. There are hundreds of different codes that your check engine light can represent. While that sounds daunting, with a little patience, tackling basic diagnostics will give you useful knowledge about your vehicle and will also allow that Check Engine Light to do what it is really supposed to do: be your guide. Unfortunately, obvious and helpful vehicle symptoms do not always accompany an illuminated Check Engine Light. Since there are hundreds of possible OBD codes, there are also hundreds of possible reasons for the light, including:
- Ignition system faults
- Transmission issues
- Emissions controls issues
- Fuel and air metering systems problems
- Computer output circuit issues
- Old Battery
- O2 Sensor
- Loose Gas Cap or Missing Gas Cap
- Bad Spark Plugs
What could cause the check engine light to come on in a Land Rover Range Rover?
When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a serious problem that could cause serious damage to your engine and come with a hefty repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow typically means something less serious but a flashing check engine light indicates that your vehicle’s engine is in serious trouble and service is needed immediately. If your check engine light is flashing in your Land Rover Range Rover, we highly recommend not to drive the vehicle and schedule Land Rover service today. Below is a list of the most common reasons your check engine light can come on:
- One of the most prevailing and frequent cause is that your Land Rover Range Rover gas cap is loose, damaged or missing. The gas cap for your Land Rover Range Rover 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 erstwhile 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 Land Rover Range Rover, first thing you should check is to make fearless the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
- Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known 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 less active 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 Land Rover Range Rover's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to pick the polite assortment 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.
- Your Land Rover Range Rover has a vacuum leak. Every Land Rover Range Rover has a vacuum system that performs a expanded range 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, excessively if they’re exposed to important heat or extreme fast.
- New Spark Plugs or Plug Wires are imperative for your Land Rover Range Rover. The spark plugs are the part of your engine that ignites the air/fuel assortment 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 you're spark plugs or spark plug wires are bad or erstwhile, 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, good to more expensive repairs.
- Issues with any aftermarket items. An aftermarket alarm, exhaust or substitute item can wreak havoc on your Land Rover Range Rover if it’s not installed accurately. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even stop the vehicle from starting. If these issues sound current, bring your Range Rover to Land Rover and have our team of certified mechanics ensure that your aftermarket items were installed correctly and aren't causing any issue. Getting accessories, excessively aftermarket parts and accessories, or using OEM parts first place might cost a little bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
- Your catalytic converter is bad or going bad. The catalytic converter is a part of your Land Rover Range Rover’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 Land Rover St Louis offers a complimentary multi-point inspection with every Land Rover service. If you have an issue with your catalytic converter and don't get it repaired, your Land Rover Range Rover 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 substitute problems from overheating.
- Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Land Rover Range Rover is what determines how much fuel is imperative 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 clear changes, identical altitude. If your Land Rover Range Rover is having trouble starting, idling rough or has a quick change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
- The battery is low or dead. The battery in you Land Rover Range Rover every scrupulous. 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 truly require maintenance. The price of a new one depends on the type of Land Rover you drive, but check our present service coupons and specials.
Check Engine Light Service Land Rover Range Rover
What do you do when you’re driving along in your Land Rover Range Rover and suddenly, a yellow light illuminates on your dash and says "Check Engine". If you’re like most Land Rover owners, your heart sinks a little 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 cost 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 Land Rover Range Rover checked as soon as possible. Ignoring that warning could end up causing major damage to expensive engine components.
When your Land Rover Range Rover's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t correct, a computer turns on your check engine light. This amber or yellow light is typically 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 Land Rover auto repair mechanics at Land Rover St Louis. There are also a number of relatively 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 experienced professional to determine the issue and repair it.
Will the check engine light reset itself?
The check engine light on your Land Rover Range Rover will usually shut itself off if the issue or code that caused it to turn on is fixed. 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 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 Land Rover Range Rover 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 Land Rover St Louis so the light and code can be double-checked and reset.
How many miles can you drive with the check engine light?
The safest bet is to decipher the code and then plan your strategy accordingly. It could be anything from a bad sensor to plug wires needing to be replaced. Since any check engine code has its own level of severity, it is not available to predict how frequent miles you can drive with the warning light on. If you check engine light is flashing, we endorse that you pull over and contact Land Rover St Louis to help indicate if your vehicle is safe to drive in or if we endorse a tow truck.
