Whether you drive one of the Land Rovers or one of the Range Rovers in the stunning collection that JLR has created, there is no doubt that you take great pride in looking after it. Sometimes though, no matter how careful you are, problems can arise and quite often they can be the fault of a glitch within the vehicle rather than anything your driving or maintenance may have caused.
Luckily the onboard diagnostics system can help you find the cause of the problem and then find the perfect solution that’ll keep your Land Rover in prime condition.
The thing is, there are so many codes, it can be a headache trying to recall what a single OBD error code could mean. So, in this month’s blog, we have catalogued some of the more common ones so you have a better idea of what problems your Land Rover may have encountered.
What is the Land Rover OBD?
OBD stands for On-Board Diagnostics and is a system that detects and diagnoses problems across your vehicle. These could stem from problems with the engine, the transmission, the emissions and more. Sensors are in various parts of the vehicle and as they detect a fault, they send data to the vehicle’s “brain.” This then has that data translated into an error code which will either be displayed on the dashboard or via a diagnostic scanner.
Why use an OBD for a Land Rover?
By identifying problems before they become major issues you can get your Land Rover to a Land Rover specialist and have them rectified. This can then save you money on repairs and help you avoid breakdowns should the problem develop into something much worse.
In some cases, you will be able to fix the problem yourself but for the most part, the expertise of a Land Rover professional will be needed. Without an OBD to show you the problem, you would not know how bad it is or what the possible solutions would be.
Luckily most vehicles manufactured after 1996 are required to have an OBD system enabling you to spot a problem before it develops and get your Land Rover back to its best quickly. Vehicles from before this time require a different approach to detecting an error so it would always be best to speak to your local Land Rover services company for help in rectifying the issue.
Deciding when to run a scan is largely up to you but it would be suggested to check it regularly. If you notice warning lights appearing or the vehicle not behaving as it normally would, put your OBD to good use and see if you can find any problems.
What are the common Land Rover OBD error codes?
If you have found that an error has developed with your Land Rover, attaching an OBD scanner to the OBD port will help you find the code and set yourself on the path to fixing the problem.
There are many codes, and we will cover a selection of the most likely as well as a few of the less likely below. Commonly a code featuring the letter P relates to the powertrain whilst when C is in the code, it relates to the chassis. Within each code, there could be additional faults, however, we have selected some of the most common faults each code is attributed to.
P0010- This code relates to engine oil being too low, a worn timing chain or a camshaft solenoid failure.
P0010- PCM failure or potential wiring issue.
PO1074- PCM software needs updating, dirty fuel injectors, faulty MAF sensor or weak fuel pump.
PO200- Defective fuel injector, faulty or corroded wiring and/or connections.
PO300- Worn out spark plugs, ignition wires or distributor cap. Low or weak fuel pressure, defective crankshaft and/or camshaft sensor.
PO441-Missing fuel cap stuck open or closed purge valve, damaged or cracked fuel tank filler neck, split or damaged carbon canister. Defective or damaged fuel tank.
PO500- Defective vehicle speed sensor, defective speedometer, defective transmission.
PO842- Transmission control failure, transmission fluid level is low.
PO901- Clutch master cylinder failure, clutch solenoid failure.
POB24/26/28/30- battery energy control module failure, high voltage battery assembly failure, wiring issues.
POC11/C14/C15- Coolant system leak, drive motor power inverter control module failure, engine cooling fan failure, water pump failure.
P2237/38- Exhaust leak, wiring issues, oxygen sensor failures or PCM failure.
P2500/501/503- Alternator failure, battery failure, wiring issues.
There are of course many others, and it is always advisable to contact your local Land Rover specialist to help should you be unsure.
How do I use an OBD scanner on a Land Rover?
With your OBD scanner, you can connect it to the OBD2 port and discover more about the problems with your vehicle. Typically, it is located on the driver’s side near the steering wheel and labelled OBD or OBD II. It will then scan the car’s system, discover the faults, and show you on the screen of the OBD scanner what they are with both the codes and the brief explanation.
You can then book your vehicle in for a Land Rover service and have the problems resolved or reset.
