Remove the oil pressure sending unit and have a test gauge hooked up and see if the sending unit is defective. If you really have low pressure the engine should be making lots of noises.

In some cases where the oil is not changed properly, the oil pump screen maybe plugging or your oil filter is defective. Fram is a good filter. If there is no problem found, replace the pressure sensor.

There may be a loose wire or the gauge or sending unit may be going bad. The first thing I would do is to hook up a temporary oil pressure gauge, not using the old one at all. With this watch gauge while driving and see what readings you get. If the readings still jump around you have a pump that is getting weak and failing, If that is the case the pump should be replaced, but with high milage you may consider rebuilding the entire engine. If the readings stay normal start checking for a loose wire at gauge or sender. Then check sender, then gauge and replace as needed.

SOURCE: oil pressure gauge reads normal when first starts.

Two things...when it reads zero, is there any engine noise (tapping or knocking)? After you rev the engine does the pressure read normal at idle and function normally, or does it go back down? Either way, you should not drive the vehicle 'till you have a mechanical gauge (yours is electro-mechanical) put on there and the actual pressure is tested. The condition may be a bad sending unit, a bad bearing or possible obstructed oil pump screen. The repair is obviously different for each one and the price is as well.

2005 FLSTCI-Oil sensor is illuminating at idle. Goes away above idle.


Don't worry about it Bro, put a lower pressure sensor on it. I've had guys crying to me that put a oil pressure gage on there Shovelhead, good pressure when first start up, after warm the gage goes to zero. Brutha, Hawg pumps ain't made to build pressure, just circulate oil is all they do. Your oil is circulating thru the engine now. Like I said, if your that concerned about it, replace the sensor.Safe trip Bro.

Where is the oil pressure switch on a chevy silverodo 2006.


What engine size , because could have come with a few different ones ? Engine oil pressure sensor is a input to the PCM - engine computer . This will turn on check engine light if thier is a problem ! What is the problem your having , oil light on , oil pressure gauge not working ?
Engine Oil Pressure Gage
The instrument panel cluster (IPC) displays the engine oil pressure as determined by the powertrain control module (PCM). The IPC receives a class 2 message from the PCM indicating the engine oil pressure. The engine oil pressure gage defaults to 0 kPa (0 psi) or below if:
• The PCM detects a malfunction in the engine oil pressure sensor circuit.
• The IPC detects a loss of class 2 communications with the PCM.

99 f-350 super duty 4x4 v10. oil pressure gage reads 0 starts and will idle. rev it up it backfires in notwr somewhere


Sounds to me that it has jumped it timeing. This will make you not have any oil pressure and will also make it back fire. You will need to replace the timeing chain and inspect the gears to see if they are worn. And if the show signs of wear change them. You only want to do this onec.

Not getting start


On some cars, if the oil pressure goes to 0, the circuit to the electric fuel pump is disabled. You need to find out why the oil pressure went to 0. It may be a switch or the wiring, but if the oil pump went out, this feature saved your engine.
