5V Supply

5V Supply

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












- Manifold absolute pressure sensor
- Charge air absolute pressure sensor
- EVAP pressure sensor
- Pedal position sensors
- Throttle position sensors

Diagnostics
A short circuit in the 5 V supply will put the throttle in limp-home mode and may be caused by a fault in the wiring harness or in a sensor fed by the 5 Vsupply. Since the two 5 V supplies are coupled together internally in the throttle body, no symptoms will appear if an open circuit occurs in only one of them.
