berg Posted April 24, 2015 Share Posted April 24, 2015 Im trying to do the above but the diagram doesnt make sense It shows me here to fully close the sub throttle valve and check theres no clearance between the gear and top screw My gear will not go high enough even with the screw fully down there is a good 10mm or more gap between the gear and the screw so i dont understand this The gear rests against the other stop screw when the valve is fully open but theres no chance of it happening when fully closed Any ideas?

Tricky-Ricky Posted April 24, 2015 Share Posted April 24, 2015 If you have the traction control disabled, which is what most do then its not necessary. Quote Link to comment Share on other sites More sharing options...
berg Posted April 24, 2015 Author Share Posted April 24, 2015 I removed the throttle body to have polished and now im stuck with a o/d light and slip control light flashing on dash which is stopping me from using manu mode on the gearbox so id like to get it sorted Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 24, 2015 Share Posted April 24, 2015 Is the butterfly itself fully closed, or partially open? You do have the drive motor off the assembly, don't you? Why people *&$~@ about with these I don't know, the forum is littered with tales of woe when they are interfered with! What price bling ehh? (Well a good 3 hours of my time, usually....) Great for me as I can do them in my sleep, and usually get the offending lights to behave so long as no hardware damage has been done Quote Link to comment Share on other sites More sharing options...

Great for me as I can do them in my sleep, and usually get the offending lights to behave so long as no hardware damage has been done I had one of these in today, dash lit up like a tree after the intake had been off for polishing! Polished turd if you ask me. The guy spends more time polishing it and clearing codes off than driving it! Should give your card out to the polishers Chris - a slogan of 'make your polished turd purr again!' Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 24, 2015 Share Posted April 24, 2015 LOL, it's so well documented on here yet people will still thrash themselves with grief for the polished look! Quote Link to comment Share on other sites More sharing options...
berg Posted April 24, 2015 Author Share Posted April 24, 2015 When i close it as far as it can go it remains partially open still just like the repair manual shows And none of the sensors were removed or tampered with when the work was done, im simply eliminating it as a potential problem as it was fine before removal Each to thier own ehh Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 24, 2015 Share Posted April 24, 2015 Is the motor drive (stepper motor) off the casting though? Without the drive motor it should be trivial to see just why the butterfly is not closing fully. It's only a shaft, butterfly, a return spring and a teeth on a quadrant... The stepper motors can give serious issues if they suffer water or polishing compound ingress though, and will jam up. They also need to be refitted correctly.

berg Posted April 24, 2015 Author Share Posted April 24, 2015 The drive motor being the bulky plastic part held on by the 4 screws? I have that off, i just followed the repair manual by steps and im at the stage where there should be no clearance when closed Do i need to do something to make it close fully as the manual doesnt state that?

Chris Wilson Posted April 24, 2015 Share Posted April 24, 2015 It should just spring shut. Never had that issue, and done loads of `em. Very odd, you should be able to see what's jamming it. Quote Link to comment Share on other sites More sharing options...
berg Posted April 24, 2015 Author Share Posted April 24, 2015 Thats odd ill have a look and see, its correct that it should be in the open position and i have to manually close it though right? At first i thought it would be the other way round I will have a check then as it definately only closes 3/4 of the way so something is stopping it I thought it was fine as the manual shows it still partially open in the diagram Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 24, 2015 Share Posted April 24, 2015 Sorry, I am a bit distracted today. It should of course be sprung fully open. That's its normal operating position of course. Then the stepper motor should close it down, in, err steps Quote Link to comment Share on other sites More sharing options...
berg Posted April 24, 2015 Author Share Posted April 24, 2015 Ok thanks i will find out what blocking it from closing then and report back As it stands with it closed as far as it can the stopper screw is nearly an inch away so somethings not right Quote Link to comment Share on other sites More sharing options...
costas1 Posted April 24, 2015 Share Posted April 24, 2015 as far as the tps calibration goes this is what i found mate http://www.supraforums.com/forum/showthread.php?450071-TPS-Adjustment-Procedure-and-Testing-Procedure Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted April 24, 2015 Share Posted April 24, 2015 Nasty things should be thrown in the bin!, first thing I did was to pull the relay to stop the dam thing stranding me as I was pulling out quickly onto a roundabout, when I went single I cut the offending butterfly and casting off and welded up........and polished:p However I don't know how they are integrated into the auto, I just threw the TRAC ECU in the bin.

Then the stepper motor should close it down, in, err steps Found the problem with the butterfly, the sub tps on the other side of the butterfly was stopping it from closing all the way, it must have been removed and not refitted correctly Now the butterfly opens and closes as it should Still got the lights on the dash though Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 25, 2015 Share Posted April 25, 2015 You will now need to set up the throttle position sensors PRECISELY. I hope no one has turned any throttle stop screws... I could have told you the sub TPS could be refitted wrongly, but you said earlier it had been polished with everything left in place.

berg Posted April 25, 2015 Author Share Posted April 25, 2015 So for that i will need to follow the repair manual guide then I shall give it a go and hope for the best I left everything in place and it didnt look like anything had been removed but it seems it may have Quote Link to comment Share on other sites More sharing options...
Big Mark Posted May 22, 2015 Share Posted May 22, 2015 What symptoms other than dash lights were you getting? I've got a weird nose when I turn the ignition off since I took off my throttle body etc. Going to record it and post it video on forum but sounds like something trying to move and cogs slipping (rubbish description I know) - - - Updated - - - What symptoms other than dash lights were you getting?

berg Posted May 22, 2015 Author Share Posted May 22, 2015 Just unable to use manu mode due to the lights, car drives as normal Still havent resolved it and have done the following 1. Tried the car with no speed converter/delimiter at all 2. re-soldered all wires for the above and triple checked against diagram 3. Tried a spare ODO 4. Replaced Throttle control ECU 5. checked resistance on the sub throttle control valve and sub TPS on the throttle body 6. Replaced both the fuse and relay for traction control Anyone know where the speed sensor is located as i need to check this now, i dont think its that though, problem only started after having the throttle body off Quote Link to comment Share on other sites More sharing options...
