its located next to the oil filter
ck oil pressure with gauge, if ok replace oil sending unit there is also a $20.00 dollars oil pressure sensor that sits underneath the engine by the oil pan area(front), this sensor can get old and display the wrong pressure in the system.
The proper fuel pressure of a 1995 Astro van should be between 55-61 psi. Checking the fuel pressure at home requires a fuel pressure gauge and knowledge of the location of the shader valve on the fuel rail.
You need to attach a fuel pressure gauge to the port on the fuel rail to measure the pressure.
Called an "oil pressure sender", it's most usually close to the oil filter.
Remove the oil pressure sensor, connect a manual oil pressure gauge to the port & start engine.You should have 10 18 psi at idle. hope it helps, Slackers Of Va.
The pressure is checked with a gauge, the electronics are checked with an appropriate scan tool and a volt/ohm meter.The pressure is checked with a gauge, the electronics are checked with an appropriate scan tool and a volt/ohm meter.
1. low oil 2. electronic oil pressure switch has failed (probably not a mechanical oil pressure gauge cause then you would see a oil line running through the firewall to the gauge. 3. short in the wiring
It's low on freon.
My oil pressure gauge is dropping to o and the oil was just changed and is full. What could cause this
it is between 35 and 47
Probably because it has a big tank that fluctuates. I could be wrong too though.
