OIL PRESSURE SENDING UNIT

DESCRIPTION

The engine oil pressure sensor is mounted on the
front of the oil filter housing. The sensor provides an
output voltage to the ECM that corresponds to the
engine oil pressure. Under certain operating condi-
tions, for example low oil pressure, it may be neces-
sary for the ECM to increase the engine idle speed to
ensue adequate engine lubrication.

The engine oil pressure sensor is a three wire sensor
with a threaded pressure port. The pressure port is
mounted to the oil filter housing through an access
hole. An aluminium seal ring seals the engine oil pres-
sure sensor to the oil filter housing.

OPERATION

The engine oil pressure sensor receives a 5- volt reference from the ECM. The sensor ground is also provided by
the ECM. The sensor output voltage varies from 0.5 to 4.5 volts depending on engine oil pressure.

REMOVAL

1. Open hood and disconnect negative battery cable.

2. Disconnect engine oil pressure sensor connector.

3. Remove engine oil pressure sensor from the
