how_supra Posted March 26, 2006 Share Posted March 26, 2006 My tip box was behaving very strangely yesterday. It was dropping down from 4th to 2nd for no reason what so ever. But after a few hundred yards it seem to sort itself out! Yesterday evening on the way home from James' my Rev counter was not working at all, although it was driving perfectly normally. Now today, on route to the gym, again no rev counter, I drove in manual mode which didn't cause too many problems. But as I left the gym and headed towards Halfords this time in auto mode, the revs were bouncing between 0 and 1500 rpm [not normal], and the car felt like it was hesitating, and sort of jumping and my engine management warning light flashed on. Anyway on the way back from Halfords, it was fine, rev counter reading right, gears changing correctly, no hesitation and no warning lights Confused I'm hoping some can shed some lights on this for me My thoughts are ECU problem - perhaps a reset will sort it out?? Speed sensor is dirty, or needs replacing Torque converter Any other suggestions?? Quote Link to comment Share on other sites More sharing options...
TRD3000GT Posted March 28, 2006 Share Posted March 28, 2006 There will be a plug that goes in to the back of the rev meter... Try plugging it back in Sorry could not resist.. You and James are having a jolly old time with your motors! Quote Link to comment Share on other sites More sharing options...
terribleturner Posted March 28, 2006 Share Posted March 28, 2006 Hardy har Chris It's really odd. You plant your foot for the kick down and as you hear the revs rise the rev counter goes DOWN. Then as you lift off it comes back up. Also it wont change gear. Doesn't happen all the time but every other i recon Quote Link to comment Share on other sites More sharing options...
how_supra Posted March 29, 2006 Author Share Posted March 29, 2006 Errrrr thanks Chris Perhaps its a sign I should get myself a proper car......................... Quote Link to comment Share on other sites More sharing options...
IanK Posted March 29, 2006 Share Posted March 29, 2006 Hi Sabrina, Sounds like a faulty speed sensor in the gearbox. Give mark at eurospec a call he should be able to diagnose it. Id give an ecu reset a go first though. Edit: although before you do that, see if you can get any error codes out of it first. Quote Link to comment Share on other sites More sharing options...
terribleturner Posted March 29, 2006 Share Posted March 29, 2006 Were off to see Mark in a few hours. Is really odd. Drove it home last night and when it worked it was fine, but when it didn't it was scary. Pulled out to overtake and then the power went and i was just sat there waiting for something to happen (Still need to sort the video Ian, i got it out but still havn't got my arse in gear. I promise that now i am unemployed i will get it done asap ) Quote Link to comment Share on other sites More sharing options...
IanK Posted March 29, 2006 Share Posted March 29, 2006 no probs. Got a few bits in the garage from my supra you might want before i put them up on here too. Hope you get on ok, it does sound like its only a speed sensor. Mark will sort it anyway, he's FTO God! Quote Link to comment Share on other sites More sharing options...
how_supra Posted March 30, 2006 Author Share Posted March 30, 2006 The car is now at Marks, he thinks its sensor related. Still a pain in the backside though. Your name came up yesterday's at Marks. He was telling me about your new car............ Quote Link to comment Share on other sites More sharing options...
IanK Posted March 30, 2006 Share Posted March 30, 2006 oh no my secrets out! yea just picked up an 2000 reg 1.6 A3 for a cheap(er) runabout for a year while i save up for a house deposit. Ill pick up another Supra after that (although this time with racelogic TC me thinks) Nice little car actually, only 40,000 miles and a nice suede interior http://www.laserlines.com/supra/a3.jpg Quote Link to comment Share on other sites More sharing options...

pistonbroke Posted April 9, 2006 Share Posted April 9, 2006 I had similar problems on my FTO. There are 2 speed sensors on top of the gearbox, one input one output. Check the multiplugs for both, mine had melted on one of them. The other thing is, there is a big grey multiplug on the front of the gearbox, the previous owner had steam cleaned the engine bay which forced water in past the seals for the plug and rusted all the pins. Got a new loom from the breakers yard and all was good. I never had a problem with rev counter though. I would put it down to a bad connection on the dial cluster, there is one of them silly plastic floppy paper circuit boards on the back of the instrument cluster, the multiplugs may not be getting a clean contact with the circuit board.

terribleturner Posted April 9, 2006 Share Posted April 9, 2006 Sabrina finally got this sorted after replacing nearly ALL the sensors on the car, ecu and upgrading to a GTO fuel pump. I'm probably wong (and i have asked and been told loads of times now) but i think it was the Ignition sensor, which of course was the last thing touched Just been out driving it while Sab's away and it's all back to normal Quote Link to comment Share on other sites More sharing options...
how_supra Posted April 9, 2006 Author Share Posted April 9, 2006 Yep it was all down to my IFS. All sorted now, with new fuel pump and leads etc, the car is running better than ever. It was odd, because he was adament that it was a completely seperate issue [my rev counter not working], but apparently it would seem that it can in some cases cause problems with hesitation. So now we know........... Quote Link to comment Share on other sites More sharing options...
Guest Vanman Posted April 14, 2006 Share Posted April 14, 2006 Yep it was all down to my IFS. Another one that wouldn't believe me. 10 minute job with a £50 sensor, job done. Quote Link to comment Share on other sites More sharing options...
how_supra Posted April 15, 2006 Author Share Posted April 15, 2006 Another one that wouldn't believe me. 10 minute job with a £50 sensor, job done. I asked the guy who had my car several times if it was my IFS and he kept telling me that it was an ecu problem. Anyway alls well that ends well.
