Guest vikerz18 Posted November 18, 2009 Share Posted November 18, 2009 Hey. I have recently got a N/A auto supra import. Drives pretty nice but recently when i pull off, it sometimes doesnt know what gear it wants. It will jerk up and down a few times then get into gear. On some occasions it takes a while for it to get into the gear it should be in.. Also on my dash it sometimes flashes on and off o/d off even when its on. The two problems dont seem to be connected but i thought i would mention it. Its not the first auto i have had. I usually drive it with 0/d on, manu off and in "D" position. Any ideas will be great.

dukenukem Posted November 18, 2009 Share Posted November 18, 2009 Any error codes? I had a problem where my car wouldn't go above 2nd. Error Codes said speed sensor and it turned out one of the hundreds of wires into the ECU (that had been spliced to fit a lap timer in Japan) had come out. Plugged it back and been fine ever since.

Guest vikerz18 Posted November 29, 2009 Share Posted November 29, 2009 I done the error code check and got code 42 from my overdrive light for some reason instead of the engine light... so that sais number 1 speed sensor? Could that be causing my problems? where can i find the number 1 speed sensor, front left? I also just checked my autobox fluid while the engine is cold and not run for about 15 hours. The fluid level is much higher than the marks for "hot" on the dipstick. I understand that the level should be on the "cold" marks at the bottom of the dipstick not at the top. thanks Quote Link to comment Share on other sites More sharing options...
Guigsy Posted November 29, 2009 Share Posted November 29, 2009 ive heared that if the flid levels are wrong it can cause problems. So i would have that checked first. Quote Link to comment Share on other sites More sharing options...
baldy Posted November 29, 2009 Share Posted November 29, 2009 auto fluid needs to be checked with the engine running and idealy hot in park the speed sensor is on the back of the trans Quote Link to comment Share on other sites More sharing options...
Supranature Posted November 29, 2009 Share Posted November 29, 2009 I had this problem the other week. Problem solved by resetting ECU. ie. disconnect the battery for 10 minutes. Simples......... Quote Link to comment Share on other sites More sharing options...
Guest vikerz18 Posted November 29, 2009 Share Posted November 29, 2009 thanks for the ideas. I will try all those things and let you know how i get on. Quote Link to comment Share on other sites More sharing options...
Ian C Posted November 30, 2009 Share Posted November 30, 2009 This is classic symptoms of a speed sensor problem (the code 42 being, of course, a real giveaway), and the speed sensor problem is usually caused by either dry solder joints on the back of the speedo, or dodgy wiring/components around a speedo convertor/delimiter. -Ian Quote Link to comment Share on other sites More sharing options...
Guest vikerz18 Posted December 3, 2009 Share Posted December 3, 2009 something else i have noticed is when the problem occurs, i can hear a hydrolic clicking noise. usually when i have the car in gear and the brake on i also hear the noise plus the engine doesnt tick over as smooth as it does when in neutral.

Guest vikerz18 Posted December 9, 2009 Share Posted December 9, 2009 I have so far had the time to reset the ecu. Since i have done that i havent had the problem but i did get a nice noise for a few miles which sounded like a loose fanbelt but i realised it was coming from the gearbox.

Either with or without the flashing OD light? I solved mine by fitting a replacement odometer ciruit board, but as mentioned if you have a dodgy speedo converter / delimiter fitted that can cause the same issues.

Guest vikerz18 Posted December 13, 2009 Share Posted December 13, 2009 that light doesnt come on. It does work though. I dont think i have a speedo converter / delimiter fitted. It clocks up in km and doesnt go above 112 i dont think. I think the dial facia was just changed. After a few days of reseting the ecu the problem returned. Im not sure wat to check/change next.

Krister Posted December 14, 2009 Share Posted December 14, 2009 You need to do the bypass odometer mod. Search it from supraforums.com, all you need to do is cut a wire and hook it to another wire. Quote Link to comment Share on other sites More sharing options...
Guest vikerz18 Posted January 8, 2010 Share Posted January 8, 2010 I think i have finally sorted it! I checked the odometer circuit board and found some cracked solder around a little module. I done the bypass odometer trick and its worked a treat! Car feels much nippier on pull off now also Thanks everyone for your input and ideas !!
