5V Supply

The manifold absolute pressure sensor is supplied with 5 V from control module pin 43. The throttle position sensor and tank pressure sensor are powered with 5 V from control module pin 42.

Diagnosis
In case of a break or short circuit on any of the two 5 V feeds, a diagnostic trouble code will be generated for the sensor in question.

The two 5 V feeds are internally isolated in the control module.
