Summary of change:
'''This page is about VAG electronically controlled throttle''' '''Overview''' This is a DBC ('''Drive by Cable''') VAG throttle body used on a large range of VAG models. The newest VAG models have DBW (Drive By Wire) throttle bodies. '''How it works''' The DBC throttle body contains * two position sensors (variable resistors) * one end switch and * a DC electric motor to adjust the angle of the throttle. Spring return to closed position ** Is this 12..14V and what max current? (are the 1.1A stepper driver channels able to drive it or not ?) ** Does it withstand 14V continuous drive even in the end-position ? (for how long?) '''Inside''' See [http://vagner.jeje.je/bilder/albums/album113/TB_Diagram.jpg DBC circuit diagram]. Pictures: http://vagner.jeje.je/bilder/albums/album113/VAG_throttlebody.jpg Can Someone tell me if the connector is micro-power-timer or junior-power-timer (likely) size? (see ConnectorSelection or tycoelectronics.com if unsure about sizes, or just measure the pin dimensions, like "2.68 x 0.8mm"). I saw an apparently matching female 2x4 one-end-rounded connector housing on the front-cover of a tyco catalog (could not find the product inside though, except in 2x4 pin microtimer size - on http://www.tycoelectronics.com ). [http://vagner.jeje.je/bilder/albums/album113/TB_01.jpg 2] [http://vagner.jeje.je/bilder/albums/album113/TB_02.jpg 3] [http://vagner.jeje.je/bilder/albums/album113/TB_03.jpg 4] note that it has 2 speed-down gears inside, about 1/7 and 1/8 ratios (1/56 effectively). Pictured throttle body is not fully motor driven. * Only throttle plate position at idle is controlled with gear motor. * Hence this is cable operated, but idle is controlled with gear motor. * Has two potentiometers, one for idle position feedback and other for measuring cable operated throttle plate opening angle. ---- '''Sources''' * VAG item number ? ** VDO unit. Throttle diam 45mm *** 030 133 064 F *** 408 237/130/004 I 3 33 99 * other suppliers ? Costs > 350 Euro. Anyone knows good sources ? Anybody knows VW partnumbers of TPS sensors ? Or good sources of any TPS sensor? * VW TPS part numbers: ** 2.0L 8v: 037 907 385 N/P/Q ** 2.0L 16v: 054 133 154 F ** G60: 037 907 385 D/M (and maybe H) ---- '''See also''' * InTake/DriveByWireThrottle * InTake/ThrottlePlates * CruiseControl
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
