Circuit Operation

CIRCUIT OPERATION
On vehicles equipped with the manual transmission, a Vehicle Speed Sensor (VSS) located in the transmission is used. Circuit K7 supplies 8 volts from the Powertrain Control Module (PCM) to the VSS. The K7 circuit connects to cavity 44 of the PCM connector.

Circuit G7, from the VSS, provides an input signal to the PCM. The G7 circuit connects to cavity 66 of the PCM connector.

The PCM provides a ground path for the VSS signal (circuit G7) through circuit K4. Circuit K4 connects to cavity 43 of the PCM connector.
