Signal Ground

The signal ground circuit Z11 connects to cavity 52 of the Powertrain control Module (PCM). The Z11 circuit provides ground for the sensors that provide inputs to the PCM. Internal to the PCM, the signal ground circuit connects to the PCM sensor return circuit (from circuit K4) and the power (device) ground circuit (Z12).

The termination point for circuit Z11 is an eyelet attached to the left side radiator closure panel.
