Sebring Convertible L4-2.4L VIN X (2004)
PCM GROUND
Ground is provided through multiple pins of the PCM connector. Depending on the vehicle there may be as many as two different ground pins. There are
power grounds and sensor grounds.
The power grounds are used to control the ground side relays, solenoids, ignition coil or injectors. The signal ground is used for any input that uses
sensor return for ground, and the ground side of any internal processing component.
The PCM case is shielded to prevent RFI and EMI. The PCM case is grounded and must be firmly attached to a good, clean body ground.
Internally all grounds are connected together, however there is noise suppression on the sensor ground. For EMI and RFI protection the housing and
cover are also grounded separately from the ground pins.
