I would start with the oil pressure sensor, sounds like it's going bad.

On my 1993 detroit 60 12.7, one day the oil pressure dropped to 15 psi and the buzzer came on , now if I drive it 4 miles, pressure low and buzzer comes on.


I can only tell you that in my Cat engine, as the crank and rod bearings wore further and further, the oil pressure also got lower and lower. Perhaps one or more of you bearings has gone bad.
Good Luck

Engine oil lamp some times blinks comes on and later when restart it does not come I have Kia Sorento 2009


The oil light will come on when ever pressure is low it ct can be as little as the oil pressure sensor is going out or you may have a blockage somewhere in the oil system try doing an oil change with mobile1 oil this may help if there is a small blockage but defiantly get the sensor checked first

Operating oil pressure for 14.0l detroit dieselseries 60


If the engine is at normal operating temperature 25 pounds is fine at idle. Also have you tested the oil pressure with a mechanical gauge, if not you should do so.

Oil pump at idle is good when car is warming up, but after it get real warm after 20 miles of driving the idle oil presure is low about 15 lbs



  • This is normal. On your car, on a cold start the pressure will be around 75 PSI. After the engine warms an oil pressure of 15-20 PSI at idle is just what it should be. The oil pressure gauge should escalate when accelerating up a bit to. If your old school like me 15 PSI mean danger but tat Caddy is just fine.

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

Hello, I have the same issue like bjmadm1234 posted. The solution suggested unfortunately does not work for my car (Dodge Grand Caravan 1997). We already exchanged the Oil pressure switch, after driving a...


I would suspect that you have a weak or failing oil pump, however before condemning the pump I would do a physical oil pressure check with a gauge. Oil pumps are not easy to replace so lets make sure it is the problem before replacing it. For reference yours can be done with the motor in the vehicle.

Physical Pressure Test:

This may require you to tuck a oil pressure gauge under the driver side wiper arm and go for a short drive to make the situation replicate. Depending on how you hook up the gauge (in place of oil pressure switch) the light will be on full time during the testing and this is ok. If you can replicate this symptom that you are reporting in the drive way in gear it is desirable as you can better read the gauge.

The oil pressure should be:

3.0L = Oil pressure should be 6 PSI at idle and 35-75 psi at 3,000 rpm with engine at normal operating temperature.

3.3L = Oil pressure should be 5 psi at idle and 30-80 psi at 3,000 rpm with engine at normal operating temperature.

You see that there is a large "in spec" region for the 3,000 rpm range as listed. I would look for the pressure to be at the higher end of the scale and the idle pressure to be right in spec. If any of these pressures are low I would suggest changing the oil pump.

If your motor is one that I have not listed here please comment back and I will provide the appropriate spec per the motor in your van.

Where is the oil pressure sensor located on a 60 series detroit


60 series detroit has oil sender on driver side near rear of engine just above the starter. It usually has 3 wires, and sometimes can be buried in the harness, so you may have to look under wiring harnesses in that area to find.
