OIL PRESSURE SENSOR (OPS)
TYPICAL
1. OPS
Oil Pressure Test
First, carefully check the condition of the connec-
tor terminals. Clean to remove dirt and corrosion
that coud affect proper operation of the sensor.
IMPORTANT:
Do not apply grease on terminal.
To check the function of the oil pressure sensor,
an ,oil pressure test has to be performed. Refer to
OIL PRESSURE TEST in LUBRICATION SYSTEM
section.
If the engine oil pressure is out of specifications,
check the points described in TROUBLESHOOT-
ING section.
If the engine oil pressure is good, check the resis-
tance of the OPS while engine is off and while
engine is running.
Resistance Test
Disconnect the connector from the OPS and use
a multimeter to check the resistance between
OPS terminal and engine ground while engine is
stopped (without oil pressure) and while engine is
running (with oil pressure).
When engine is stopped the resistance is infinitely
high (normally open switch).
When engine is running and the oil pressure reach-
es 180 - 220 kPa (26 - 32 PSI), the resistance of
the OPS is close to 0
Ω
.
If resistance values are incorrect, replace OPS.
If the values are correct, check the continuity of
the wiring harness.
Disconnect the EMS ECU connector A from the
EMS ECU and check continuity of circuit 6.
If wiring harness is good, try a new EMS ECU. Re-
fer to EMS ECU REPLACEMENT procedures else-
where in this section.
Otherwise, repair the connector or replace the wir-
ing harness between EMS ECU connector and
OPS.
