Land Rover Freelander 1.8 2004 - MIL & Hill decent lights on, code C1147 - Fixed #

Posted by John Kennard on February 11, 2013, 1:00 pm

Year of Manufacture *: 2004

Freelander SALLNABA74A420274 18K4F

Hi got this one in at the moment and scanned the above code C1147 CAN Signal engine speed error and it is permanent, also had C1151 Can gear box data failure: C1116 Supply voltage too low (vehicle running) both these have cleared & it is a manual gearbox.

Both the engine management lights & hill desent warnings are on the dash. I have checked the CAN wiring from Engine ECU to ABS I beleive it then goes through to the dash. I have as yet to get the vehicle in & scope the CAN signal. Has any one had a similar problem & can help direct me in the right direction please?

Hello John, I think C1147 should be "CAN signal throttle position switch error". Hope this helps, Alan.

I had the same after head work on a Freelander and found it to be throttle potentiometer poor connections.

Thanks for the replies, Alan you are dead right this is a throttle position switch error, not as described by Autodiagnose as an engine speed error. You have helped me get a more accurate picture; thank you.

Gwyn thanks I have replaced the throttle pedal switch which is basically a magnet and adjusted it and wallah we have communication and no code. Thanks to all the suggestions and your help I just wish I could be more helpful with my knowledge at times. Thank you, Guys.

Glad to have been of some help John. I've also had my fair share of bad translations sending me up the garden path. Maybe someone from Autodiagnos might be reading or is Autodiagnose a different company?

Morning John,

>>> this is a throttle position switch error, not as described by Autodiagnose as an engine speed error <<<

Just thinking out loud really, but it looks like something has been lost in a translation.

"throttle position" = IDLE and Idle is a set engine speed/ state.

If the system was not "seeing" the Idle switch contact then it would assume that the engine speed was not correct.

What do you think ?

Hi Alan & Mark, sorry it is Autodiagnos misinterpreting the code description. Life is difficult enough interpreting codes without having poor descriptions leading you up the garden path. As soon as you pointed that out, I plugged in the Wurth WOW in and it came up with your description; the correct one. I was always led to believe Autodiagnos was good on early Land Rovers how wrong you can be! Once I had a good interpretation I was able to get my Land Rover TIS disks out and study the correct wiring loom & check the correct sensor.

I have a number of Autologic manufacturers but just don't see enough LR's to justify their out lay. But I will say that Autologic always pride themselves in giving the manufacturers code interpretation word for word.
I have recently invested in the LR/Jag Dongle by Diagnostic Associates for pass through on 2005 models onwards also the service reset dongle which is brilliant for resetting those pesky service lights. Not sure how complicated or difficult the new Jag/ LR SDD software is to use as we have only just received the software and not had a late vehicle in yet to trial yet. Have any of you guys out there used it yet?
