Signal Ground

Circuit Z11 connects to cavity 5 of the Powertrain Control Module (PCM)connector. The Z11 circuit provides ground for the sensors that provide inputs to the PCM.

Circuit Z11, which supplies a ground for the PCM sensors, has the same termination point as the Z12 circuit. This ground terminates at the right headlamp ground located at the right front frame rail.

If the system loses ground for the ganged circuits the vehicle will not operate. Check the connection at the ground eyelet.
