List of possible OBD codes
If you dig into your Range Rover’s On-Board Diagnostic (OBD) system, you might stumble upon a few relevant trouble codes that can shed light on the cutting-out issue.
Here are some potential OBD codes you might come across:
- P0335: Crankshaft Position Sensor A Circuit Malfunction: This code suggests that the crankshaft position sensor is not functioning correctly, affecting the engine’s combustion process.
- P0340: Camshaft Position Sensor Circuit Malfunction: A faulty camshaft position sensor can disrupt the timing of fuel injection, leading to engine stalling.
- P0351: Ignition Coil A Primary/Secondary Circuit Malfunction: This code indicates a problem with the ignition coil, which can cause intermittent power loss and engine cutting out.
- P0500: Vehicle Speed Sensor Malfunction: A malfunctioning vehicle speed sensor can confuse the engine management system, resulting in unexpected engine stalling.
Now, let’s get into the nitty-gritty of what might be causing your Range Rover to play this annoying game of “cutting out.”
Here are some common culprits:
- Fuel Pump Failure: A failing fuel pump can struggle to provide the necessary fuel pressure, leading to engine stalling.
- Ignition System Issues: Faulty ignition coils, spark plugs, or ignition control modules can disrupt the combustion process, causing your Range Rover to cut out.
- Faulty Sensors: Crankshaft, camshaft, or vehicle speed sensors that are on their last legs can throw off critical engine functions, resulting in undesirable stalling episodes.
- Clogged Fuel Injectors: Over time, fuel injectors can become clogged with debris, affecting fuel delivery and causing engine misfires or stalling.
- Electrical Gremlins: Loose wiring connections, bad grounds, or faulty relays can wreak havoc on your Range Rover’s electrical system, leading to sudden cutouts.
Can it be fixed without a mechanic?
Ah, the eternal question: can I fix this problem without rushing to the mechanic? Well, in some cases, you might be able to tackle the issue yourself.
However, it’s essential to assess your comfort level and mechanical skills before diving into complex repairs.
If you’re confident in your abilities, you can give it a shot but don’t hesitate to seek professional assistance if needed.

How to fix it
Now that you’re all geared up with the necessary parts and tools, let’s dive into the step-by-step process of fixing this pesky cutting-out issue in your Range Rover.
Keep in mind that these instructions provide a general overview, and it’s always crucial to consult your vehicle’s specific repair manual for accurate guidance. Safety first!
- Identify the Culprit: Use an OBD-II scanner to retrieve the trouble codes from your Range Rover’s diagnostic system. This will give you a starting point in pinpointing the root cause.
- Check the Fuel System: Inspect the fuel pump and filter for any signs of malfunction or clogging. If necessary, replace them.
- Test the Ignition System: Examine the ignition coils, spark plugs, and ignition control modules for any visible issues or signs of wear. Replace any faulty components.
- Inspect and Clean Sensors: Check the crankshaft, camshaft, and vehicle speed sensors for loose connections, frayed wires, or physical damage. Clean or replace as needed.
- Clean Fuel Injectors: Use a fuel injector cleaning kit to flush out any debris and deposits that might be clogging the injectors.
- Check Electrical Connections: Inspect all wiring connections, grounds, and relays for loose or corroded contacts. Repair or replace damaged components.
- Put Everything Back Together: Double-check that all components are properly installed and secure. Ensure all connections are tight.
- Test and Monitor: Start your Range Rover and let it idle for a while to monitor for any rough idling or stalls. Take it for a test drive to confirm that the cutting-out problem has been resolved.
Potential alternative causes
If you’ve gone through the troubleshooting and repair process outlined above and your Range Rover still decides to play the cutting-out game, here are a couple of additional causes to consider:
- Air Intake Issues: A significant air leak in the intake system can disrupt the air/fuel mixture and potentially cause engine stalling. Inspect the air intake components for any leaks or damage.
- ECU Failure: In rare cases, a failing Engine Control Unit (ECU) can erroneously interrupt vital engine functions, resulting in unexpected stalling. Consult a professional for diagnostic testing.
What is the most common cause of a Range Rover cutting out?
One of the most common causes of a Range Rover cutting out is a malfunction in the fuel system, such as a clogged fuel filter, a failing fuel pump, or issues with the fuel injectors. Electrical problems, like a faulty ignition system or sensor issues, can also lead to engine cutouts. Regular maintenance and diagnostic checks are essential to identify and address these issues.
Are there any simple DIY fixes for a Range Rover that keeps cutting out?
While some basic checks like ensuring clean air filters, proper fuel quality, and tight battery connections can be done by the owner, diagnosing and fixing complex issues that cause engine cutouts may require professional expertise. If the problem persists, it’s recommended to consult a mechanic or Range Rover specialist for a proper diagnosis and repair.
How often should I clean my Range Rover’s fuel injectors?
The frequency of cleaning your Range Rover’s fuel injectors depends on factors like the quality of fuel, driving conditions, and maintenance history. Generally, fuel injectors might need cleaning every 30,000 to 60,000 miles as part of regular maintenance. If you notice a decrease in engine performance, fuel efficiency, or rough idling, it could be a sign that the injectors need cleaning.
Can faulty wiring connections cause my Range Rover to cut out?
Yes, faulty wiring connections can lead to engine cutouts in a Range Rover. Issues with the ignition system, sensors, or even the fuel pump can be caused by poor or corroded wiring connections. Regularly inspecting and maintaining wiring connections can help prevent such problems. If you suspect wiring issues, it’s advisable to have a professional diagnose and address the problem.
How much does it cost to replace a Range Rover’s ignition coil?
The cost of replacing a Range Rover’s ignition coil can vary based on the model, year, and location. On average, the cost can range from $150 to $400, including parts and labor. However, prices may differ depending on the specific circumstances and whether the replacement is done at a dealership or an independent mechanic.
The frustration of a Range Rover that keeps cutting out is something many owners know all too well. Various factors can contribute to this issue from fuel pump failures to faulty sensors and electrical gremlins.
While some repairs might be within reach for DIY enthusiasts, weighing your skill level and seeking professional help if needed is crucial.
With the right parts, tools, and a methodical approach, you can bid farewell to those unexpected stalling moments and get back to enjoying the open road in your trusty Range Rover.
