Supra Steve 856 Posted April 30, 2006 Share Posted April 30, 2006 Right, my problem started when my auto box was goin mad and kept selecting gears all over the place flicking between gears like mad even when just going a steady 40mph, i was very confused why this was doing this However i also have a TurboTimer fitted that takes the signal from the No 1 Vehicle Speed Sensor (pink wire) off the ECU, and tells you how fast your going, and what i have noticed is when the autobox is playing up like this, the speed on the turbotimer is also going mad!!! one second its sayin 247kph then 156kph,then 216kph then 13kph then back up again when im actualy only going about 10mph lol (example) now im guessing that the autobox is changing gears (as it should) to go along with these speeds its getting signals for, so what could be makeing this sensor do this and where is this sensor mounted?? also FYI, i dont have a TSD fitted, and my speedo converter (kph to mph) is fitted directly onto the back of the main speedo dial, nowhere near the ECU, also this is not a constant problem, sometimes the car drives fine and the signal is fine, then other times i will drive it for a lil while and then the signal starts to go mad again. how can i fix this signal, and stop this from happening so that my autobox works correctly again? has anyone got any ideas why this is doing this? I desparately hope you can help me!! thanks, Steve Quote Link to comment Share on other sites More sharing options...

Supra ST Myster Posted April 30, 2006 Share Posted April 30, 2006 have you tried removing the turbo timer from the pink wire and checking to see if thats the problem?? the turbo timer should go ideally on the back of the gauge cluster blue/red wire.

Supra Steve 856 Posted May 1, 2006 Author Share Posted May 1, 2006 at one point i removed the turbo timer completely, but it still does it! Quote Link to comment Share on other sites More sharing options...
Jake Posted May 1, 2006 Share Posted May 1, 2006 I would start by removing the speed converter and putting it back to stock. Has the ECU harness been hacked about? You want to check the soundness of all the wires. Also check the wiring going into the back of the Odometer - it can cause some very strange behaviour.

Supra Steve 856 Posted May 2, 2006 Author Share Posted May 2, 2006 checked. and nope its still doing it, any other ideas??? Quote Link to comment Share on other sites More sharing options...
Fifty Posted May 2, 2006 Share Posted May 2, 2006 Jakes correct - try a new speed convertor; this has happened to me! Rich:d Quote Link to comment Share on other sites More sharing options...
Supra Steve 856 Posted May 2, 2006 Author Share Posted May 2, 2006 just so i know for sure, this speed converter is this little bit of circuit board with wires on that is soldered directly onto the back of my speedo?? Quote Link to comment Share on other sites More sharing options...
Supra ST Myster Posted May 2, 2006 Share Posted May 2, 2006 just so i know for sure, this speed converter is this little bit of circuit board with wires on that is soldered directly onto the back of my speedo?? Correct! Worth looking at the back of the odo plug, there is a pink wire and a blue/red wire, does it look untouched? Quote Link to comment Share on other sites More sharing options...
Supra Steve 856 Posted May 8, 2006 Author Share Posted May 8, 2006 you would never expect it!! its as simple as this..... its the connector plug that goes into the back of the odo! it has loose and bad contacts, and im guessing this is confuseing the ECU and screwing up the system, but give the connector a wiggle and it fixes the problem! now all i need to do is make these very small connectors inside the block make a better contact without bustin them lol. thanks for your help guys!

Jake Posted May 8, 2006 Share Posted May 8, 2006 Told ya! ...but you said you checked that? Quote Link to comment Share on other sites More sharing options...
Supra Steve 856 Posted May 8, 2006 Author Share Posted May 8, 2006 i thought i did! unpluged it pluged it back in, seemed ok!, but on closer inspection i noticed the connector on 1 of the wires was bent inside the connector, not the easyest to fix trust me!!
