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.
