I hear people asking all the time what kind of oil pressure they should see. Yes, I was one of them long ago. Maybe this is stupid, maybe it's not, but I thought that this photo from the 93 brochure should give a general idea of what it should be. I know this isn't really specific, but I figure if you run the same speed and rpms as in the photo, then a healthy engine should show about the same oil pressure that Mazda does. Like I said, I just threw it up here in case it may assist someone.

I apologize for the poor photo quality. I just didn't want to open up my brochure too much and damage it.

 

ohh sht my engine is fuckd then.... lol.... but again.. my wire to the sensor is about to rip off.. only one tinny wire holding.. i gotta fix that...

 

The stock oil pressure sensor is prone to failing. I would just install an aftermarket oil pressure and temperature gauges for piece of mind.

 

The guy is in third gear btw. I haven't had the connection issue yet so I'd like to beat it to the punch. I assume the best way is to remove the connector and use electrical contact cleaner all over it. Maybe a brass brush also if it will fit. I'm not going to replace my sender unit until it starts acting up.
