Check the oil pressure. Check for oil
leakage and check the oil pump and oil
strainer if out of specification.
NOTE:
• If the oil pressure sensor is removed, the
engine idle speed will increase about 900
r/min due to an oil pressure sensor mal-
function condition. Delete the diagnosis
record using the YDIS after checking the oil
pressure.
• The actual oil pressure may vary depend-
ing on the temperature and viscosity of the
engine oil being used.
Checking the oil pressure sensor
1.
Connect the test harness to the oil pres-
sure sensor.
2.
Start the engine and warm it up for 5 min-
utes.
3.
Measure the oil pressure sensor input
voltage. Check the wiring harness con-
nection or replace the ECM if out of spec-
ification.
4.
Measure the oil pressure sensor output
voltage. Replace if out of specification.
