Circuit Operation

CIRCUIT OPERATION
From the Powertrain Control Module (PCM), circuit K7 supplies 5 Volts to the manifold absolute pressure (MAP) sensor. Circuit K7 connects to cavity A17 of the PCM.

Circuit K1 delivers the MAP signal to the PCM. Circuit K1 connects to cavity A27 of the PCM.

The PCM provides a ground for the MAP sensor signal (circuit K1) through circuit K167. Circuit K167 connects to cavity A4 of the PCM.
