Oil pressure sensor-gctid365631

[Guest]

First I would like to Thank Rick E. from Fairview, Oregon for all his help in providing me with much valuable information. I really appreciate his help. thanks to him and other members advice I will be out on the water enjoying my boat this summer. I will be posting some pictures later on, but for now here is another question.is there a way to check if the oil pressure sensor is working..? and how do you buy a replacement do you go by the first numbers or last numbers stamped on the sensor.here a couple of pics.Thanks again.

Hector, you are welcome, and that's good news.

These senders are available through a Sierra dealer or a Marine parts center.

The only thing to specify would be Single or Dual Station and the impedance re; the gauge psi range.... 0-80 or 0-100 for example.

Watch the p/n for an "S" or a "D"..... it's not always obvious.

Volvo Penta 872064 in Sierra is SIE OP24891 but I believe lists this for Dual Stations

Oil Pressure Sender (Psi/Station: 80/Dual Stationdatcon 025041, Volvo Penta 872064, Marine Power 0940102, Crusader 700403 Teleflex Ia 15003 Replaces

About $24.00 compared to Volvo Penta at $44.00

Hi there... I think you are looking for this:

Edit: Dang... Rick beat me to it!!!

A simple check for the oil gauge and sensor would be to disconnect the wire at the sensor/sending unit and ground it to the engine block with a jumper wire while the key is on engine NOT running. If your oil pressure gauge goes to the maximium, your gauge and wiring are probably ok. If while the engine is running and the sensor is connected you have an incorrect oil pressure reading at your gauge, either the the sensor is malfunctioning or you have an oil pressure problem with the engine. I would verify the actual engine oil pressure with a mechanical type gauge screwed into the port that the oil pressure sensor is screwed into in either case.

Good luck

Matt, if you'll use the resistance of a test light to take the blue wire to negative, you won't risk damaging the gauge.

I'll check as you guys have said. I bought new set of gauges. the wireing in the boat is brand new, so it is not the wireing. when I turn on the engine it goes up to 100 and it won't move. I don't know how old this oil pressure is so, I just will replace it. by the way what will be the normal gauge reading..?these are the new gauges.Thanks again.
