DESCRIPTION
The 2-wire, electrical/mechanical engine oil pressure sensor (sending unit) is located in an engine oil pressure gallery.
OPERATION
The oil pressure sensor uses two circuits. They are:
The oil pressure sensor returns a voltage signal back to the PCM relating to engine oil pressure. This signal is then transferred (bussed) to the instrument panel on a CCD bus circuit to operate the oil pressure gauge and the check gauges lamp. Ground for the sensor is provided by the PCM through a lownoise sensor return.
