i did search to start off

i have prosport gauges oil temp and oil pressure

i have the gauges grounded, and the sensors grounded to chassis.

my oil pressure is acting like an rpm gauge though.

can anyone pointme in the right direction, beside saying get different gauges.

 

Can you be more specific? exactly whats it doing--what are the min readings at idle? Try swapping leads at the switch.

 

when i start the car, the gauge reads as if its rpm. its not steady at all unless its at idle.

swap leads?

 

Well it's obviously picking up a signal from somewhere relating to the output of your cars electrical system.

Where did you wire the gauges to i think he was asking?

 

oil pressure goes up with rpm... that is, until you get to the point where the oil is not returning to the sump as fast as it is being pushed into the engine. Oil temperature also has an affect on this.

Normal cars have what car people refer to as "idiot switches" where it will show a constant pressure unless it drops below something ridiculously low (3-4psi).

 

How did you wired it up ?

 

i used my factory MR gauges for power and ground for the gauges.(red, orange are one in the same on gauges so they always are amber lit) no white connected. then i ran the green wire to the sensor of each wire. and then grounded the sensors to a bolt near the engine bay.

 

my gauge is doing this exact same thing.


idle its steady, goes up with rpm.

 

You are the guy the idiot switch is made for.

 

maybe im not understanding how this gauge is SUPPOSE to read then? shouldnt it have a constant oil pressure? i know the oil pump goes up with RPM as well, but doesnt make sense lol

 

Literally one of the dumbest automotive related threads that I've read in the last 15 years. Congrats!(?).

 

hahaha
A little harsh but the ignorance is true.

Your gauge is fine, oil pressure has various different pressure steps in it based on RPM for various reasons.

 

Why? Because someone who has never used/seen/operated an oil pressure gauge wanted one, installed it on their own, and then wanted to be certain it was working correctly?

Where would anyone have even learned how an oil pressure gauge is supposed to work/read in day to day motoring? Cars don't use them (really), so it isn't like it's common knowledge.

People come here for help and ask all sorts of stupid questions. We're all car people, and we're a dying breed (like it or not), so why be a dick to someone that's learning?

 

Are you just upset because you don't know how electronics work? Also, I am guessing that you were unaware that oil pressure is not constant as well.

signal fairies runnin' around the engine bay and output of the cars electrical system shenanigans

 

So I guess it's working properly
