The 5-Volt supply circuit is a common supply circuit which is bussed
internally of the Engine ECM. The supply voltage is 5.0 0.16 volts.
Output of the 5-Volt supply circuit is at Engine ECM J2-46 circuit T997-
OR, J2-47 circuit L730-OR, J2-48 circuit R997-OR, and J1-42 circuit
997-OR. The 5-Volt supply circuits are supplied to the intake manifold
pressure sensor terminal 1, the engine oil pressure sensor terminal 1,
the fuel rail pressure sensor terminal 1, and the turbocharger air inlet
pressure sensor terminal A.
