Nic Posted March 12, 2007 Share Posted March 12, 2007 If it is speed related, then it could be that the stock auto front spoiler has been removed. Do you have the button for the auto spoiler, try turning it off and see if you still get the warning triangle. If it's not that it may be a dodgy kmh/mph speedo conversion.

Nic Posted March 12, 2007 Share Posted March 12, 2007 Try checking for fault codes to see if the ECU has logged the problem. See how to guide here: http://www.mkivsupra.net/vbb/showthread.php?t=35920 Quote Link to comment Share on other sites More sharing options...

Angarak Posted March 12, 2007 Share Posted March 12, 2007 Sounds speed sensor related. If you do the diagnostics check as per Nics link, you will most likely get a 42 error code. If your car is an import (which I believe it is) and its speedo is reading MPH instead of KMH then it will have a speed converter either in the passenger footwell where the ECU is or behind your dials. It could be a knackered one like Nic suggested. Alternatively, it could be a faulty Odometer. Does your milage/tripometer still increment? It could also be related to the Active Spoiler as Nic has mentioned, or a loose speed-related wire to the ECU in the passenger footrest. A search for "Code 42" will give you plenty of reading materials and causes/solutions. Quote Link to comment Share on other sites More sharing options...
Kranz Posted March 12, 2007 Share Posted March 12, 2007 The light you're getting on the dash is the 'check engine' light, meaning that it has detected an engine fault. Could be any of the sensors that has picked up a fault, so you'll need to do the fault code check as Nic said. Why it happened at 60 on the motorway????? Could be just that the fault is only seen by the ECU at higher loads and that it has to exist for a certain length of time to set the fault?

Mas Posted March 12, 2007 Share Posted March 12, 2007 its your speedo mate, it comes on at 3k+ REVs or lets say 60ish+ miles, a thor racing delimiter/speed convertor would do the job. Quote Link to comment Share on other sites More sharing options...
Kranz Posted March 12, 2007 Share Posted March 12, 2007 a thor racing delimiter/speed convertor would do the job. And its adjustable so you can read exact speed by setting it up with a GPS. Handy if you change wheels & tyre sizes. Quote Link to comment Share on other sites More sharing options...
SupraStar 3000 Posted March 12, 2007 Share Posted March 12, 2007 yes, Sounds speed sensor related to me too. Is the car delimited? Quote Link to comment Share on other sites More sharing options...
Angarak Posted March 12, 2007 Share Posted March 12, 2007 Forgot to mention, if your odometer/tripometer does increment, then the signal from the #1 speed sensor is OK (eliminating that as a cause). Quote Link to comment Share on other sites More sharing options...
crashoverride Posted March 13, 2007 Author Share Posted March 13, 2007 ok guys, well odo works fine as for it being delimited i havent got a clue. how would i find out? Quote Link to comment Share on other sites More sharing options...
imi Posted March 13, 2007 Share Posted March 13, 2007 hi nic, no i have a manual 5speed N/A, as for the speedo convertion i have no idea mate Time you take it to a professional to have a look at it then. It sounds speed related, probably a dodgy speed converter OR a dody installation of a speed converter. Quote Link to comment Share on other sites More sharing options...
StuartW Posted March 13, 2007 Share Posted March 13, 2007 I had the same problem on mine @60MPH or 3K RPM's The top speed de-limiter is a red wire on the ecu (PAssengers foot plate) Un plug the bullet connector to totally eliminate it. Then remove your dash and locate a set of wires connecting to the back of the speedo Think it's Negative & Positive Then on ebay they sell a 110MPH speedo face (About a tenner) Then wire the aftermarket KPH to MPH into the trip computer and all should work ok....That's what i did anyway on my 1995 J spec. Does your power steering seem very light and twitchy at speeds over 50 ish?? Or buy a decent speed convertor/de-limiter... Disclaimer....This is fact but only what i learned from my car Knightrider Quote Link to comment Share on other sites More sharing options...
R3DG3CKO ROB Posted March 13, 2007 Share Posted March 13, 2007 I have the same problem... came back with a code 42 which is speed sensor... I think it's a dodgy delimiter as Its not had the converter fitted I'm gonna replace the whole lot with a delimiter and converter Quote Link to comment Share on other sites More sharing options...
crashoverride Posted March 14, 2007 Author Share Posted March 14, 2007 sounds like the best thing i can do is drop it into thor and get them to look at it for me realy, might make the trip over the weekend Quote Link to comment Share on other sites More sharing options...
supra666 Posted March 14, 2007 Share Posted March 14, 2007 its your speedo mate, it comes on at 3k+ REVs or lets say 60ish+ miles, a thor racing delimiter/speed convertor would do the job. My Car did the same thing, get the delimiter replaced and you will be fine!! Quote Link to comment Share on other sites More sharing options...
