I have a 1989 Range Rover that has a EFI light lite up on the dash. I do not have a manual and most of the people I ask about it have no idea what to do to fix the problem. Obviously, most people start off by saying Electronic Fuel Ignition and thats where it stops. Can anyone help me figure this long awaited problem out and tell me what needs to be replaced in order to fix it. Thanks | ||

The 87-89 RR have a fairly simple muliti-point EFI system. If you detect no problem with the running of your engine, you can turn off the dash light. Just remove the both batery cables from the battery, starting with the negative. This will reboot the computer and turn off the light. If there is a problem with the running of the engine you should: Replace the plugs, plug leads, dist cap/rotor with LR parts. Check the electrical connections to the ig coil. Replace and/or adjust the throttle position sensor. Check the connection to the air flow sensor. Adjust sensor(which rarely needs replacing) Check the wiring to the O2 sensors which may have been melted etc. Replace the O2 sensors. Those are about the only problems which will cause the EFI light to turn on with the CU type EFI system. | ||

how about misfires or fuel system issues... i'v been told that using some gas additive for a couple tanks should resolve the problem. i have my light on as well... mine lights bright then it's dim and sometimes very dim almost off then when i stop and just idle it lights up brighter. engine runs fine though... so i'm not too worried. i should try rebooting the thing... | ||

Thanks for the tips. My RR runs fine too, as Hanchung said his does. I have changed the plugs and wires. I have disconnected the battery cables starting with the negative lead and yes it does make it go off. After a couple miles of driving it comes back on. I priced an oxygen censor and not sure if I want to spend $256.00 for a part that may not make it run any better or make the dash lite go off.Where is the the air flow sensor located i order to check the connection or adjust? And how about the location of the throttle position sensor? Any more info would help. | ||

I think I have exactly the same problem like you have, Jim. I somehow have accepted the light, dont notice it any more. It runs ok, but very rich at idle and startup. You can smell it and it would fail our MOT - Test. At fast idle the mixture is all right. There is a test procedure from Rover and all needed to go through it is a volt/ohm tester/multimeter (in case one lacks a Lucas-Testbook). I fear I have it in german only. There is another one in the Haynes manual (in english). I sure could try to e-mail it to you. Would be nice to hear if it is an oxygen sensor or not at fault (that�s what I guess). I for myself simply do not have the time to work on my RRC for the last and next time. I�m very grateful the RRC has proven reliable so far (We include it in our prayers, (hope that makes sense  ). Just post me if you want. [email protected] |
