GlennMR2 Posted March 18, 2005 Share Posted March 18, 2005 heres my problem... i have been getting the engine man light coming on if i keep the revs over 3000. and the light stays on untill the car is switched off. now i am getting code 42 which is number 1 speed sensor, i was looking on some old threads about this and also had some help from migster on trying to find out why im getting this, the car has had no de-limiter fitted and still runs and counts up in KM... i have taken of the box on the passanger side footwell to have a look at the ecu where the speed signal wire goes in and this is what i have fount (look at pic) now i dont know what the hell that has been done for but that might have something to do with the problem does anybody have a clue as to why that extra bit of pink wire has been added like that... thanks Quote Link to comment Share on other sites More sharing options...
Tom Posted March 18, 2005 Share Posted March 18, 2005 Easy get a trl converter and all your problems will be solved. Quote Link to comment Share on other sites More sharing options...
GlennMR2 Posted March 18, 2005 Author Share Posted March 18, 2005 thats on my list of things i need but why would that solve that problem i have because there is no de-limiter on there at the moment so it shouldnt muck the signal up in the first place Quote Link to comment Share on other sites More sharing options...
Ian C Posted March 18, 2005 Share Posted March 18, 2005 Well, that pink wire is the No1 vehicle speed sensor wire, and OMG it's got a scotchlok on it, and correct me if I'm wrong but is the additional bit of pink wire just cut and floating around in the breeze?! -Ian Quote Link to comment Share on other sites More sharing options...

GlennMR2 Posted March 18, 2005 Author Share Posted March 18, 2005 Did Paul E sell you this car??

dangerous brain Posted March 18, 2005 Share Posted March 18, 2005 That wire could be some sort of converter or speed sensor for something else that has since been removed. With it flapping around in the breeze so as to speak it could and probably is shorting out. For now remove that crap scotch lock clip (which should have been done instead of just cutting the wire) and stick some insulating tape over the area that has cut insulation. If that cures your problem then you know that was what was causing it. If however your problem persists have a search again as there are a couple of things cause this and are documented as I had a code 42 and I fixed it using the advice I found under the search (mine turned out to be a dodgy wire at the odo connecter where a crap speedo conversion had been done) Quote Link to comment Share on other sites More sharing options...

Matt Harwood Posted March 19, 2005 Share Posted March 19, 2005 That is the wire you'd need to connect to to de-limit the car. It's also used as a sped pulse pick-up for other gadgets. If the pink wire decides to touch the casing of the ECU it's sitting above. It'll definatly cause a error signal! Alternatively, that crappy Scotchlok could be breaking the circuit going to the ECU, again resulting in an error code. Remove the Scotchlok first, (and the extra bit of wire), and you may find what's causing the problem. Quote Link to comment Share on other sites More sharing options...

Dragonball Posted March 20, 2005 Share Posted March 20, 2005 No idea Glenn m8 - never went near the ECU - or any codes before Check out the above suggestions and if you need it looked at let me know Cheers Quote Link to comment Share on other sites More sharing options...
GlennMR2 Posted March 20, 2005 Author Share Posted March 20, 2005 cheers paul..ive now removed the extra bit of wire so but havent realy given the car a blast to see if the light comes on... Quote Link to comment Share on other sites More sharing options...
Ian C Posted March 20, 2005 Share Posted March 20, 2005 You have to put the engine under load for I think 8 seconds over 3 or 4k rpm before it'll light the light, but you may notice overly light power steering before that... -Ian Quote Link to comment Share on other sites More sharing options...
GlennMR2 Posted March 23, 2005 Author Share Posted March 23, 2005 well i think ive fixed the problem now as i have no new codes coming up now that bit of wire is removed Quote Link to comment Share on other sites More sharing options...

CJ Posted March 27, 2005 Share Posted March 27, 2005 Check your brake fluid level and top it up. That sometimes causes this problem too. Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted March 27, 2005 Share Posted March 27, 2005 If it was low brake fluid, it wouldn't be the engine management light, it would be the handbrake light accompanied with the main warning light. You need to do a diagnostics check to find out what fault code has been stored this time. Quote Link to comment Share on other sites More sharing options...

Fifty Posted March 27, 2005 Share Posted March 27, 2005 taken from supraforums (search error code 42) "Before you go and pull your tranny try tapping on the odometer. The signal from you speed sensor goes through the odo before it gets to the ecu. It is a known problem for the signal to get "lost" in the odo." I have had this code recently and my speedo went OFF at the moment its working again; likely to be a dodgy connection in my case. Worth a try though? 50 Quote Link to comment Share on other sites More sharing options...
Willson Posted March 27, 2005 Share Posted March 27, 2005 I would definately open the scotch lock on that pink wire and check that the wire is still good. Quote Link to comment Share on other sites More sharing options...
GlennMR2 Posted March 28, 2005 Author Share Posted March 28, 2005 new update my car must have been delimited at one stage because i got upto 141.6 mph and it was only because i backed off the throttle otherwise it would have went more...

dangerous brain Posted March 28, 2005 Share Posted March 28, 2005 Have a look at the back of the odometer a dodgy wire at the odo caused my code 42. Also check all the wiring that goes into your speedo and see if there are any loose wires there. Quote Link to comment Share on other sites More sharing options...
