its on the left side of the motor..you get to it through the wheel well..i change alot of them
Check with manual gauge - if pressure normal - could be defevtive oil pressure sensor or gauge
A pressure gauge indicates actual pressure and a differential pressure gauge indicates the difference in pressure.
The fuel tank pressure sensor is for the EVAP system. It has nothing to do with the fuel gauge sending unit.
THE NORMAL GAUGE PRESSURE SHOULD STAY AROUND 12 TO 19 P.S.I
The stock oil pressure sensor on a 97 Saturn can be replaced with an oil pressure gauge for poundage info by first unscrewing the existing sensor. The new sensor can then be screwed into place and wiring ran to a suitable pressure gauge.
You can pressure test with a gauge using sensor location
replace oil sensor unit
The oil pressure sensor sends a reading to the gauge so you can moniter the engine's oil pressure. No oil pressure means the engine is in big trouble.
Most oil pressure gauges operate by a varying voltage. The oil pressure changes the resistance in the oil sensor, causing the gauge to change readings.
Oil level and oil pressure are different. You don't need to have full oil to get normal pressure.
It will be a oil pressure sensor
Either the gauge or the gauge's sensor is broke. Has the oil & filter been changed in the vehicle lately?
