00:00What does the check engine light mean on a Land Rover?

00:03The check engine light in your Land Rover isn't something to ignore.

00:07Whether it's a simple issue or a serious one, this warning light signals that your vehicle needs attention.

00:14Understanding what it means can help you avoid expensive repairs and keep your vehicle running smoothly.

00:20Here's a detailed look at what it could indicate.

00:23Loose or missing gas cap

00:25A loose or missing gas cap disrupts fuel pressure and triggers the warning light.

00:30Faulty oxygen sensor

00:31This sensor monitors exhaust gases. Failure leads to poor fuel efficiency and emissions.

00:38Failing catalytic converter

00:40Converts harmful exhaust gases. Failure causes rough driving and higher emissions.

00:45Malfunctioning mass airflow sensor

00:47Incorrect air intake readings affect engine performance and fuel usage.

00:52Warner dirty spark plugs

00:53Bad spark plugs can cause engine misfires, poor acceleration and increased fuel consumption.

01:01Failing ignition coil

01:02An ignition coil problem interrupts spark delivery and reduces engine power.

01:07Bad fuel injectors

01:09Dirty or clogged fuel injectors prevent proper fuel delivery causing misfires.

01:16Transmission system malfunction

01:17Transmission issues affect how the engine performs, often lighting up the check engine icon.

01:24Dead or weak car battery

01:25A weak or failing battery may trigger fault codes stored in the computer system.

01:30Sensor malfunction or glitch

01:32Faulty or dirty sensors like crankshaft or camshaft sensors can lead to false alerts.

01:38Overheating engine

01:39If your engine temperature rises abnormally, it may illuminate the check engine light.

01:45Low oil pressure

01:46A sudden drop in oil pressure can trigger the light and should be checked immediately.

01:52Exhaust gas recirculation issues

01:54A faulty EGR valve disrupts emissions control and triggers warning lights.

01:59Software or ECU faults

02:01Programming bugs or outdated software in the engine control unit can cause system alerts.

02:07Clogged air filter

02:08A dirty air filter restricts airflow, reducing engine efficiency and possibly triggering the warning light.

02:15What you should do next

02:16Light on but steady, drive cautiously.

02:20Get it checked soon, your car may still be drivable but not efficient.

02:24Flashing light, stop immediately

02:25A blinking light means a serious issue, pull over and seek professional help.

02:30Get a professional diagnostic scan

02:32Only a certified technician can accurately identify the problem code and repair it.

02:38Avoid guesswork repairs

02:39Don't replace parts blindly, incorrect fixes could waste time and money.

02:44The check engine light is more than just a warning, it's your Land Rover asking for help.

02:48From minor fuel system problems to serious engine or transmission issues, early diagnosis can prevent bigger trouble.

02:56Always get your Land Rover checked by a professional to ensure a safe and reliable ride.
