Where under the hood does the stock oil pressure gauge plug in at, cause i got the car back after putting the new clutch kit in and the gauge was pegged out and now it dosent even move, also how is the emergency brake connected in the car, 90 gxl n/a thanx

 

the sender is under the oil filter.

 

That wire is right in the way of their hands when they would be messing around with the slave cylinder. Chances are they either damaged the wire or just disconnected it from the sender. It's a "clip on" type wire and it is right under the oil filter.

 

ok i thought thats the one that it was, but it is connected but the gauge still isnt working, there is oil all over the sender and the clip you think that may be the prob, or is there a fuse that might have blow, or something....

 

The clip must be clean and secure or you'll get bad readings. If the other gauges are working then it's not a fuse. It'll be a problem with the gauge itself.

 

can you connect aftermarket gauges to the sender? if so how?

 

No, you must use the sender designed for (and usually supplied with) your gauge.

 

if the gauge was pegged and now it dosent work what does that mean, could it do this because the the connection itnt clean, or because the sender is bad? or a short circut?/?
i dont feel secure without the pressure sensor...

 

If you ground the sender wire (i.e. it falls off the sender and touches the engine or chassis) it will peg the gauge at the top. I'd guess that if you left it like that for long it would fry the gauge and it would no longer work.

 

Is there any where besides RB that make an adapter for and after market sender? just wondering

I don't want to highjack your thread, but I will have a similar problem on my 13B-RE. I don't remember to have seen an oil pressure sender on it ? Somebody knows where it is ?

Thanks

 

the sender wire was connected it never was off the sender, but the guy said that the gauge was pegged and then just went to zero and it hasent worked since then, i cleaned it and everything else, the whole transmission was pulled is there anyway that it go pinched or is that imposible...

 

All Mazda rotaries use the same location. See the pic above.

If I were you I wouldn't bother trying to make it work. Just go buy a proper aftermarket oil pressure gauge.

 

Make your own. Buy a block of aluminum one inch thick. Cut it two inches wide and three inches long. Drill holes in it to match the oil filter pedestal. Then drill and tap a hole to intersect the oil filter feed hole and install your favorite aftermarket sender unit.

Buy gasket material from Pepboys for a buck fifty and make gaskets to fit. Done. In fact done did that myself for two engines. I like the words done did following one another.

You should be able to make five or six units for the price of a RB unit. Maybe more.

Don't know of a place to buy metal in small quantities? Go online and you'll find several hits.

 

ok i think its the gauge itself cause the wire going to the oil pressure sender has 12 volts going to it and i also tested the sender itself and it is operating fine, is there anyway to replace or fix the gauge?or is there anything else i should check, i dont want to get an aftermarket one cause i think it looks bad to have non functional gauges in the dash....

 

An aftermarket gauge provides a far more accurate reading. The stock gauge has practically no scale so you can only guess at what its reading really is. This is far more important than a non-functional gauge.

 

no more ideas on the stock gauge
