PIP Signal Operation
The Hall effect is a process in which current is passed in one direction through a slice of semiconductor material. By passing a magnetic field through
this same semiconductor, a small change in voltage is produced in the output device.
The magnetic field stays strong and the voltage is high when one of the vane openings is in the gap between the Hall device and the permanent magnet.
In this case the switch is OFF and the Hall Effect does not send a signal. When the TAB enters the gap, the armature cuts off the magnetic path to the
Hall device and its voltage drops. In this case the switch is ON and the Hall Effect device sends a signal.
Signature PIP
When the ECA reconizes the narrow tab of the signature PIP rotary vane cup it identifies number 1 cylinder at 10° BTDC. The width of the PIP signal
generated by this tooth is smaller than that of the other teeth.
The signal can also be used by the TFI-IV module if the Spark Output (SPOUT) signal from the ECA is lost.
