I accidently put like 2 extra quarts of oil in...... The guage was reading nothing, I swapped it out with an extra oil pressure sender. Now it reads crazy high..

I am going to drain the extra oil out and see what happens.. Would extra oil bring the pressure up that much or is the sensor bad waht do you think?

 

my gauge always reads past 110 psi

its just faulty

 

You could put 10 pressure senders in and get 10 different readings... best thing to do is get a mechanical gauge and thread it in place of the sender for testing

 

What's faulty, the guage or the pressure sender? I don't see how it could be the guage. Isin't it more likely to be a wiring issue (dirty connections, short somewhere)?

My guage read nothing (never lifted from way below 0) for the longest time. Now i've reconnected it to the sender and it pegs once it gets power.

 

The only time Mine ever pegged out I redid the connection at the sender and it went back to normal. make sure the connection is ok before you go about doing all this extra work, I hate when I do that.

 

Is it electical? Did you use teflon tape? If so, remove it. No chit, my autometer did the same thing. Searced the net, and found exactly what I am telling ya. I removed the tape, wallah, works perfect.

It is electrical.. But i didn't use the teflon tape. I am going to install a aftermarklet guage this week and test it out...

 

Huh? Will wrapping tape around the wires make the guage peg?

'cause that's what I did... and it's pegged

 

i had the same problem. so i took out the sender and put in a fitting that feeds oil directly to my aftermarket oil pressure gauge. so now theres no mazda sender or mazda wire connected to it. but my stock gauge is still pegged. even with nothin there. but the aftermarket gauge says my oil pressure is ok. i dont know what to think

I had put teflon on the sending unit. I can not explain why it pegged the gauge, but it did.
