supraspeed Posted January 18, 2009 Share Posted January 18, 2009 speedo and odo not working......are the wheels turning? i have the same problem at the moment i'd check the wires behind the dials and see if any have been pulled out. unfortunatly my other dials don't work either after swapping them so my problem is somewhere else Quote Link to comment Share on other sites More sharing options...

dangerous brain Posted January 18, 2009 Share Posted January 18, 2009 If the speed sensors weren't working the ecu wouldn't get a speed signal and the car wouldn't run at all. My monies on a dodgy speedo convertor. Quote Link to comment Share on other sites More sharing options...
stevie_b Posted January 18, 2009 Share Posted January 18, 2009 (edited) As DB said.... Does the supra have a DSC fitted to change the speedo readout from kph to mph? If so, a broken DSC can cause the speedo and odo not to work. Does it have any error codes logged? Bear in mind the speed sensor error code (for example, the infamous code 42) *usually* is a result of faulty wiring behind the dash or a duff DSC, rather than a faulty speed sensor itself.

Aero-M Posted January 18, 2009 Share Posted January 18, 2009 Sound the same as mine. I Blaim the cheap convertor from ebay as it stop after this was fitted, Im going to try and get one of the Thor converters Quote Link to comment Share on other sites More sharing options...

My monies on a dodgy speedo convertor. the vss is a magnetic pick up tht will not stop the engine running as the engine runs a crank and cam shaft sensor which determines the correct time for the ecu to pulse the injectors and initiate spark.
