If oil level is OK, then it is possible that the warning light pressure switch which is screwed into the engine oil pressure system is faulty and setting off light and needs replacing. There could even be oil leaking out of the switch. The switch is usually located near the oil filter and will have a wire connected to it.
If after replacing switch and light still comes on, check to make sure wire is not making contact with the engine because of cracked insulation or it could also mean badly worn engine bearings. It is unlikely to be the oil pump as these hardly ever fail.

How to fix.my throtleboard


It seems you haven't been taking enough care on your car up to the point the whole cylinder head is worn out leaking oil from the inlet means both the valve stamp seals,valveguides ,oil scrapper rings valves and timing belt worn out. The timing jumped making the piston hit the valves damaging the guides and seals, oil started to come into cylinder and during comp%ssion it is pushed through the valves to the inlet until it damanges the throttle body.the D4 pump is also faulty, low pressure if the car can't rev. Better do cylinder head service and buy another D4 pump before condemning the throttlebody

1988 toyota 4x4 pickup check oil light is staying on. checked oil level and was full.why does the light stay on


It means your oil pressure is too low to safely run engine. Causes might be a worn oil pump, a failed oil pump gasket, clogged oil passages from sludge, or badly worn crankshaft bearings.
If your toyota is not burning oil, or very little, I would take a look at the oil pump on your engine. After removal, they can be checked (and repaired) with a feeler gauge for proper working condition, but most people just replace with new.
If you want to be certain about the pressure reading, you can check pressure with a mechanic's oil pressure gauge. You have to run the engine just long enough to get a good reading on the pressure gauge, a moment or two.

2000 Toyota 4runner oil light was blinking but now stays on. Oil is clean and full??? could it be a senor or the pump. The truck seems to be running good.


Oil sending unit. You can check this yourself with an oil pressure gauge. or send the job out to a repair shop. The thing you want to know is that your oil pump is putting out the correct pressure. The sending unit has a little filter in it that gets clogged or the unit itself goes bad. Have it checked out no biggie.

Oil Pressure light stays on. Oil reservoir is full,oil level light goes out and dipstick shows full oil. What could cause this?


It occurred to me that you may find it by unplugging wires on the few items under the hood which may appear they could be the oil pressure sending unit.

The light should go out when the wire is unplugged, and if it does it is bad. That's your continuity test.

If you unplug the oil pressure sending unit and the light does not go out, the cause of the oil light staying on is something other than the oil pressure sending unit.

RE pete cass posting: I believe that if the sensor is diconnnected, the oil pressure light will not light (at least because of the oil pressure sensor switch being disconnected) -- the symptom here is the light won't go off. The switch is closed with oil pressure below 10-15 PSI and open above that oil pressure -- this is a normally closed switch.
