Manifold Absolute Pressure Sensor

From the Powertrain Control Module (PCM), circuit K6 supplies 5 Volts to the Manifold Absolute Pressure (MAP). Circuit K6 connects to cavity 43 of the PCM, and cavity 1 of the sensor connector.

Circuit K1 delivers the MAP signal to the PCM. Circuit K1 connects to cavity 29 of the PCM, and cavity 3 of the MAP connector.

The PCM provides a ground for the MAP sensor signal (circuit K1) through circuit K4. Circuit K4 connects to cavity 51 of the PCM connector, and splices to cavity 2 of the sensor connector.
