mogster69 Posted April 6, 2009 Share Posted April 6, 2009 Hi all. I have a supra TT and it has a speed sensor problem. Can this cause damage running it like this as i need to drive to Wales from Scotland.............. Quote Link to comment Share on other sites More sharing options...
Scott Posted April 6, 2009 Share Posted April 6, 2009 Speed sensor as in the hub? If so i can't see it causing any issues other than dropping into snowmode every 5 mins lol. Just turn off the TC and be careful if you don't have experience with TT's. If you mean cam shaft position sensor then don't touch it.

Scott Posted April 6, 2009 Share Posted April 6, 2009 Not 100% which ne it is. i just got told a faulty speed sensor.............hmmmmmmm s**t! Wheel speed sensors simply tell the ABS and Traction control whats going on with the wheels. If the sensor doesn't work the ABS and TC go iffy. Nothing to worry about for driving purposes, other than stating the obvious braking and handling issues, as long as you use your melon. If its something to do with position sensors or anything on the actual engine i would be very cautious. The wheel speed sensor brings on the ABS warning light and the ! warning light on my car (facelift). Don't know if that helps you any. Are you buying this car?

patrikbrunt Posted April 6, 2009 Share Posted April 6, 2009 just sounds like a dodgy speedo converter? mine wasnt wired in properly and I kept getting the warning light come on if you revved over 3000 for 5 secs or so, also caused the OD light to flash.

mogster69 Posted April 6, 2009 Author Share Posted April 6, 2009 Thats whats happening. How do i fix this and can it cause engine damage?? Quote Link to comment Share on other sites More sharing options...
patrikbrunt Posted April 6, 2009 Share Posted April 6, 2009 I cant see how it would cause engine damage, its only an electrical problem. The issue with mine was that the pink speed sensor wire to the ECU had been spliced into a turbo timer, which had consequently been removed and so the ECU was not getting the signal and was flagging up an error. Once the wire had been reconnected it resolved the problem. But I believe a faulty speed converter can cause the same problem, something to do with the ECU getting conflicting speed signals?

mogster69 Posted May 7, 2009 Author Share Posted May 7, 2009 Its a code 42....... Can it cause a problem and how do i fix the problem?? Quote Link to comment Share on other sites More sharing options...
chris2o2 Posted May 7, 2009 Share Posted May 7, 2009 42 could be faulty speed sensor, but more than likely the buffer circuit, do a search on how to fix. - Originally posted by Bondango That search button is magic Quote Link to comment Share on other sites More sharing options...
