CIRCUIT OPERATION

Circuit K7 supplies 8 volts from the Powertrain Control Module (PCM) to the camshaft position sensor. The K7 circuit originates at cavity 44 of
the PCM connector.

Circuit K44 from the sensor provides an input signal to the PCM. The K44 circuit connects to cavity 33 of the PCM.

The PCM provides ground for the camshaft position sensor signal (circuit K44) through circuit K4. Circuit K4 connects to cavity 43 of the PCM.

Helpful Information
Circuit K7 also splices to supply 8 volts to the crankshaft position sensor and vehicle speed sensor.

Circuit K4 also splices to supply ground for the signals from the following:
-

Upstream heated oxygen sensor

-

Downstream heated oxygen sensor

-

Crankshaft position sensor

-

Throttle position sensor

-

Manifold absolute pressure sensor

-

Engine coolant temperature sensor

-

Knock sensor

-

Intake air temperature sensor

-

Vehicle speed sensor
