Land Rover Troubleshooting retrieving fault codes. Rovers 1. 99. 0 1. Sketchup Pro 2015 License Key Free Download. Rovers 1. 99. 6 and newer Rovers European Standard OBD II fault codes. Rovers do not have any user accessible diagnostics. However, they are simple vehicles. Land Rover engine numbers. Most older Land Rovers have had at least one engine change in the past. Land Rover engine designs did not change often. Winch Books Toyota Land cruiser Repair manuals About Toyota Landcruiser.

LR_His_Page_4_Image_0003.jpg' alt='Land Rover Serial Numbers' title='Land Rover Serial Numbers' />The most common causes of an EFI light are. Improperly adjusted or faulty worn out throttle sensor. Ignition misfire. Melted wires to the O2 sensors. Damage to the airflow meter connector. Damage to the ignition coils push on or screw on connections. Other faults are rare. Note These vehicles have both a Check Engine light and a Service Engine light. Check engine means you have a problem. Service engine means its been about 5. The information below pertains to Check Engine. These fault codes will appear on a two digit display found under the passenger seat. Note that although the display can indicate fault codes up to 9. You read the codes by removing the side panel of the seat base Range Rover or looking at the display under the back of the seat Discovery. I have provided identification for each fault code. In many cases the text refers to test xx. These tests are found in the Land Rover Workshop Manual in the fuel injection section. Some fault codes point to a failed sensor, some indicate an engine fault that has caused the sensor to deliver an out of range signal, and some code may indicate either or both. Do not be too quick to replace parts on the basis of codes alone. Here is how you clear codes once youve read them and addressed the faults. Switch ignition on. Disconnect serial link mating plug, wait 5 seconds, then reconnect. Switch ignition off and wait for main relay located under the passenger seat in Range Rovers to drop out. Switch ignition on. The display should now be reset. If there are other faults, the next one will be displayed. Otherwise the display will be black. If there is more than one fault repeat these steps to clear each fault until the display is blank. If you clear a code without performing a repair it and the EFI light may or may not return. Some codes are set by intermittent conditions that do not occur often. Other codes signal serious faults that are detected immediately upon startup. On to the list of codesNothing shown on display. Either nothing is wrong or the display is broken. Code 0. 2 Power interruption. This code means power to the ECU has been disconnected and the truck has not yet been started. This code should go away as soon as the vehicle is started for the first time. Appearance of this code while driving may signal a problem within the ECU. Code 1. 2 Airflow meter. Usually signals a problem with the airflow meter or the connector which can fall apart or become damaged. Refer to test 1. 9, continuity test procedure. Code 1. 4 Coolant sensor. Usually indicates a bad fuel injection coolant sensor. May also indicate a bad engine thermostat or a stuck viscous fan clutch. Refer to test 1. 4, continuity test procedure. Principles Of Population Genetics Hartl Pdf. Code 1. 7 Throttle potentiometer. Usually indicates a bad throttle position sensor. Refer to test 1. 7, continuity test procedure. Code 1. 8 Throttle potentiometer input highairflow meter low. Usually indicates a problem with one of the two mentioned parts. Refer to tests 1. Code 1. 9 Throttle potentiometer input lowairflow meter high. Usually indicates a problem with one of the two mentioned parts. Refer to tests 1. Code 2. 1 Fuel tune select. Identifies that the tune select resistor is open circuit refer to tune select resistor test. The tune resistor is embedded in the wire harness. This code may indicate damage to the wire harness. Code 2. 3 Fuel supply. Check fuel system pressure, test 2. Code 2. 5 Ignition misfire. This code indicates that an ignition system misfire has been detected. Codes 4. 0 or 5. 0 indicate on which bank the misfire has occurred. Code 2. 8 Air leak. One way to check for small leaks is by spraying choke cleaner at the joint you want to check while the motor is idling. A change in tone indicates the choke cleaner is being sucked into the engine. Check for air leaks in the following areas Hose, air flow meter to plenum. Breather system hoses to plenum. Brake servo hose. Vacuum reservoir hose fresh air solenoidDistributor vacuum advance. Hose, purge valce to plenum. Injector seals. Joint bypass air valve to plenum plenum chamber to ram housing ram housing to inlet manifold inlet manifold to cylinder head bypass air valve hose. Code 2. 9 ECU memory check. If this code appears all other faults are unreliable and must be ignored. Use the procedure below to clear the code and see if it re appears. If it does, your ECU is almost certainly bad. Procedure leave battery connected switch ignition off wait for approximately 5 seconds disconnect ECU plug. ECU plug switch ignition on and check display unit. If fault code 2. 9 is detected again, swap out the ECU for another one and retest. Code 3. 4 Injector bank A The display will indicate if the injectors are causing the engine to run rich or lean. If the bank is running rich, check for faulty injector wiring and connectors, stuck open injectors. If the bank is running lean, check for faulty injector wiring and connectors, blocked injectors. Code 3. 6 Injector bank BAs code 3. A injectors. Code 4. Lambda sensor A left bank. Code 4. 5 Lambda sensor B right bank. If one of these fault codes 4. In addition this fault will be displayed if the vehicle has a condition which causes it to run very lean or very rich on one side example a vacuum leak or a bad injector. This code often appears in conjunction with the misfire codes in cases of bad ignition misfire cross firing plug wiresIf both codes are displayed, the voltage supply to the heater coils of the sensors must be checked. Check for 1. 2V appearing on the O2 signal lead, and check the heater circuit for shorts. Code 4. 8 Stepper motor. Check base idle speed as follows. First remove and clean the idle motor and the port it screws into. Clean the throttle body as well. On the top of the throttle body you will see a hole possibly covered by an anti tamper plug for the base idle adjuster. Remove the air bypass hose from the throttle body, which will cause the engine to speed up to 2. Unplug the connector to the idle motor after 5 seconds then reconnect the hose. Squeeze the hose shut with needle nose vise grips and adjust the base idle using an allen wrench to give an idle speed of 6 7. Get the lowest speed you can that gives smooth running and does not stall when blipping the throttle. Screw in for slower idle, out for faster idle. Reconnect the idle stepper and remove the vise grip and you should be done. In addition, refer to tests 1. Check road speed sensor refer to test 2. Code 4. 0 Misfire bank A left bank. Code 5. 0 Misfire bank B right bank. If one fault code 4. Spark plugs. Ignition leads. Distributor cap. Injectors if code 3. A or 3. 6 bank B displayed. If both codes are displayed, check the following components common to both banks. Distributor cap. Distributor rotor. Coil and its associated connections. Distributor pick up air gapAmplifier. Injectors if code 3. Code 5. 8 Group faults 2. This indicates that a fault has been registered that is caused by the fuel supply or an air leak but the exact fault cannot be identified. Check all items outlined under codes 2. Code 5. 9 Fuel thermistor Refer to test 1. Code 6. 8 Road speed sensorrefer to test 2. Code 6. 9 Gearswitch Refer to test 2. Code 8. 8 Purge valve leak Refer to test 9 and 1. All 4. 0. SE and 4.
