2.5t throttle body wiring Bosch 0 280 750 146 (part number 30711552)

[surrey_100e]

Hi,
Im trying to find out what the relevant wires are on the bosch throttle body found on the Focus ST/RS, and C30 2.5turbo models part number 30711552. So far ive found the following.

1 -
2 - ground
3 - +5v
4 -
5 -
6 -

There should be. Motor +, Motor -, Butterfly Sensor 1, Butterfly Sensor 2

If anyone can help that would be much appreciated.

Regards
Martin

Well well well...

I was only asking about this project....


About 2 years ago lol.

No idea what wires you need mate but it's nice to see the project ongoing

There's a marked up diagram although a different engine, may be some use

Hope this helps...

Going on the second image with the ecu pins, info for a B5354T7 2009 model with a 30711552 throttle body:

TB Pin	Control module terminal	Signal type	Ignition on	Idle	Miscellaneous
1	A75	Throttle unit motor, control signal (-)	-	PWM signal U top=Ubat Pulse ratio 0-100%. The polarity of the control signal switches when the damper motor is to be deployed in the opposite direction.	The throttle motor is controlled using a PWM signal from the integrated power amplifier in the Engine Control Module (ECM) measured to terminal #A74
2	A14	Throttle position (TP), signal ground	U=Ulow	U=Ulow	-
3	A19	Throttle position (TP) sensor, power supply 5 V	U=5 V	-	-
4	A74	Throttle unit motor, control signal (+)	-	PWM signal U top=Ubat Pulse ratio 0-100%. The polarity of the control signal switches when the damper motor is to be deployed in the opposite direction.	The throttle motor is controlled using a PWM signal from the integrated power amplifier in the Engine Control Module (ECM) measured to terminal #A75
5	A88	Throttle position (TP) sensor circuit 2, signal	U≈4-0.4 V	U≈4-0.4 V	The voltage varies depending on the position of the throttle. U decreases with increasing throttle opening.
6	A65	Throttle position (TP) sensor circuit 1, signal	U≈ 0.4-4 V	U≈ 0.4-4 V	U varies depending on the position of the throttle. U increases with increased throttle opening.

That's a great help thanks very much, where did you find that information?
I know the project has taken longer than anticipated, things get in the way, and I don't know where the time goes, but it's all done, just finishing off a few bits on the engine loom. It's turns over and everything.

Info is from a Volvo tech document.

Lovely project, I like the attention to detail throughout the whole car, everything looks so clean
