Guest champ_supra Posted June 24, 2009 Share Posted June 24, 2009 Can anyone tell me where my throttle position sensor is, I'm so blonde when it comes to finding parts in my car! Also can i adjust it myself and how easy is it to get to and adjust?? Also has anyone got any driving tips for me for tomorrow, I'm off to bedford autodrome with my mate who has a nissan skyline r33 N1 spec gtr and i need to get a few extra horsepower? Cheers guys!

Guigsy Posted June 24, 2009 Share Posted June 24, 2009 the first thing you will be told is "its not a race" and "no timeing equipment" so dont worry about who has the biggest cock and just enjoy pushing yourself. Also - Why do you need to change the throttle position? Have fun. Quote Link to comment Share on other sites More sharing options...

Guest champ_supra Posted June 24, 2009 Share Posted June 24, 2009 I need to change it because i took it for a diagnostic yesterday at DS Automotives and it came up with 3 fault 41, spees vehicle sensor, 42 throttle position sensor and 47 throttle position sensor 2, every time i pull up to a junction and i put my foot on the clutch and the revs drop right down and then the car cuts out.

SteveR Posted June 24, 2009 Share Posted June 24, 2009 Code 42 isn't the TPS. I'm sure that's the regular error that crops up - speed sensor, no? Quote Link to comment Share on other sites More sharing options...
shima60 Posted June 24, 2009 Share Posted June 24, 2009 not to sure on the code but if it is the speed sender is your car an import as it could be the mph conversion maybe the solder is getting weak? notice any random speed jumps on your speedo? and to set your tps if thats the issue all your really need is a multimeter Quote Link to comment Share on other sites More sharing options...

Guest champ_supra Posted June 24, 2009 Share Posted June 24, 2009 Shima60 - Yeah one of the faults was to do with the speed sensor, I will check the solder to make sure! Cheers for the tip. Luckily I'm an engineer so I can commandeer a multimeter from work! (my job does come in handy lol!) I haven't noticed any random jumps on the speedo but will keep a look out! SteveR- Cheers for the error codes! Great help! Can either of you tell me where the tps actually is?? Pics or a good description would help?? If you guys have any more sparks do share them with me I need all the help i can get! Im so nervous about working on my car as don't want to ruin it! I'm definitely doing to become a full member! Everyone is so helpful! Quote Link to comment Share on other sites More sharing options...
Homer Posted June 24, 2009 Share Posted June 24, 2009 The TPS is on the throttle body, the other side of where the accelerator cable connects to it. Here you go, middle of the pic, the one with the catelogue number highlighted: Quote Link to comment Share on other sites More sharing options...
Aero-M Posted June 24, 2009 Share Posted June 24, 2009 When I brought mine it was doing the same thing, cutting out. My error code said tps, I unpluged it and centralised it. unplugged the battery for a while, plugged it all back in, problem solved. It has run perfectly ever since and the code went away.

Homer Posted June 24, 2009 Share Posted June 24, 2009 Aero-M rasies a good point, after doing work on the car it's a good idea to clear the error codes so no 'old' ones remain. The easiest method is to disconnect the battery for 20 seconds or so. Quote Link to comment Share on other sites More sharing options...
Ian C Posted June 24, 2009 Share Posted June 24, 2009 If you guys have any more sparks do share them with me I need all the help i can get! Im so nervous about working on my car as don't want to ruin it! One important tip here is that the screws which hold the TPS in place are made of a ridiculously soft metal and are very very easy to round off when trying to undo them. You need to really make sure you've got a perfectly fitting screwdriver, it's in square, you push hard into the screw, and turn carefully. If you round those buggers off it's a monumental pain to get them out with molegrips. I use an angled screwdriver from halfords, it gets in there without having to move the PAS fluid reservoir out the way and fits spot on. You can't go wrong with centralising the TPS as Aero-M says. I've taken mine off many a time and always put it back to the point. Oh, another tip, the moving sensor armature inside it is preloaded against the throttle butterfly so if you undo the screws far enough it'll spring off You just need to crack them a bit for adjustment purposes. -Ian Quote Link to comment Share on other sites More sharing options...
Guest champ_supra Posted June 24, 2009 Share Posted June 24, 2009 Wicked advice cheers everyone! Now I should be able to get it running perfectly for my track day tomorrow! Homer and Ian C I would like to become a full member of the supra club, What is the easiest way for me to do this? I dont have paypal or anything. Will either of you be in my neck of the woods at all soon? Thanks again to everyone for giving me advice! Quote Link to comment Share on other sites More sharing options...
stevie_b Posted June 24, 2009 Share Posted June 24, 2009 Code 42 can usually be safely ignored, just in case you've still got it after resetting the ECU. I wouldn't usually advise ignoring error codes, but in this case it *should* be OK to do so, at least until you get time to sort out the dry solder on the odo unit or replace a faulty aftermarket speed converter that's probably causing it.

Guest champ_supra Posted July 3, 2009 Share Posted July 3, 2009 Hey again guys! Well I attempted to fix my throttle control sensor I managed to adjust it to what to me looks center. The revs now run at just slightly over 900 for a bit then drop slightly to about 600-700 revs! Is this right? I also disconnected the battery to reset the ECU but only the negative lead and it seems to have taken away the problem, although when i turn the engine on, it chugs a couple of times, no longer then 2 seconds but just wondering if i have done something wrong or if i should simply try and adjust it again? Cheers again guys! Quote Link to comment Share on other sites More sharing options...

Cheers again guys! I don't know anything about the throttle position sensor, but the rest sounds OK. Disconnecting just the negative battery cable is fine. The ECU takes a few minutes of driving to re-learn the proper idle, but I can't think why it should chug. Quote Link to comment Share on other sites More sharing options...
