[cefiro_drifta]

my other question is wat/where is the TPS thingy ???

[kam-325i]

Part number 24 in picture, its found directly underneath the Throtle Body.



It is a switch that is used to tell the ECU how much throttle you are using.......sort of.......

It has three positions/signals.
1 Throttle Closed (idling)
2 Throttle Open (normal driving)
3 WOT = Wide Open Throttle. (Foot to the floor!)

[march109]

Can you see it in the pic I posted its there? shall I add more pretty colours?

[cefiro_drifta]

is it a good idea to clean the TPS ??? i found that there was a shed load of crap on the throttle body so might just take it all apart and clean it

anything i need to becareful of ie clips braking, things springing out unexpectidly ??

[march109]

I wouldn't take it apart TBH, spray some carb cleaner down there and flush out with compressed air, or more carb cleaner!

[cefiro_drifta]

cool thanks mate .. i had some carb cleaner and on there all day sunday cleaning it but thought it was only goin the outside and a lil of the inside... ICV is off tonight to get a clean
