5V supply

5V supply







The following sensors are supplied with 5V from control module pins 69 and 46. The two 5V supplies are internally coupled to each other in the throttle body.


Manifold absolute pressure sensor

Charge air absolute pressure sensor

Differential pressure sensor, tank

Pedal position sensors

Throttle position sensor




Diagnostics

A short circuit on the 5V supply will put the throttle in limp-home mode and can be caused by a fault in the wiring harness or a sensor supplied with 5V. As the two 5V supplies are internally coupled in the throttle housing, no symptoms will appear if there is a break in just one of them.
