Circuit/System Description

The engine control module (ECM) has 3 internal 5 V reference circuits. Each internal reference circuit provides external 5 V reference circuits for

more than one sensor. A short to ground or short to voltage on one external 5 V reference circuit can affect all the components connected to the

same internal 5 V reference circuit.
