Sensor power supply2 circuit
Description
ECM supplies a voltage of 5 V to some of the sensors systematically divided
into 2 groups, respectively.
Accordingly, when a short circuit develops in a sensor power source, a
malfunction may occur simultaneously
in the sensors belonging to the same group as the short-circuited ...
