eto po kasi ung case ko, when my car is idling the oil pressure light is on (di naman ganoon ka-strong ung pag-ilaw nya, medyo dim lang.) then pag-ini rev ko na sya or pinatakbo, nawawala na...ok naman ung oil level ko,
ano kaya ang posibble cause, hope you can help me guys..sabi ng friend ko ung oil sending unit daw un, tama ba sya? saka ano ba yung oil sending unit?

September 2nd, 2010 12:48 PM #2Check first the oil level by pulling out the dipstick. The oil pressure sending unit is located at the engine block just below the intake manifold. If its body is wet and leaking with oil, better to replace it.

September 2nd, 2010 07:31 PM #3it could be the sending unit, its a piece of sensor with wire connected to it.
or it could be the oil pump itself is the problem.

September 2nd, 2010 07:55 PM #4You should checked it immediately by a mechanic. They are right there are only two possible cause of this problem. Mabuti kung the problem is the oil sending unit aka oil pressure switch lang, annoying lights lang problem but if it is really an oil pump discharge tlaga then the consequence could be big, as it would seize up your engine.
(Sample procedures below for a Honda engine) ** halos same lang except for wires colors and pressure ratings.
Oil Pressure Switch Test
Remove the YEL/RED wire (A) from the engine oil pressure switch (B).
Check for continuity between the positive terminal (C) and the engine (ground). There should be continuity with the engine stopped. There should be no continuity with the engine running.
If the switch fails to operate, check the engine oil level. If the engine oil level is OK, check the engine oil pressure. If the oil pressure is OK, replace the oil pressure switch.
Oil Pressure Test
Special Tools Required
Oil pressure gauge attachment
Oil pressure gauge
If the oil pressure warning light stays on with the engine running, check the engine oil level. If the oil level is correct:
Remove the engine oil pressure switch, and install an the special tools. (basically a hose with a pressure gauge)
Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem before continuing.
Allow the engine to reach operating temperature (fan comes on at least twice). The pressure should be:
Engine Oil Temperature: 80°C (176°F)
Engine Oil Pressure:
At Idle: 70 kPa (0.7 kgf/cm2, 10 psi)
minimum
At 3,000 rpm 340 kPa (3.5 kgf/cm2, 50 psi)
(min-1): minimum
If the oil pressure is NOT within specifications, inspect these items.
Check the oil screen for clogging.
Check the oil pump

hmm.well nagnyayari lang naman na umiilaw ung oil pressure indicator ko when the engine is already in hot temperature (siguro mga 1 hour na takbuhan saka na sya nag-iilaw ilaw ng konti) actually pag naka kambyo ako sa-drive un(basta pag ung mga times mabababa ang menor),....when i switch it into PARK or NEUTRAL..nawawala na ung ilaw nya...auto tranny kasi ung akin e..
well thanks for the advice guys..

Try changing the oil. It might have lost its viscosity and is not thick enough to extinguish the light at idle
thank you its good naka timing chain pala. yan din concerns ko sa used car like sa dati kong...
