oil pressure sensor

[justin1642]

My oil pressure gauge isn't working and i don't know where the sensor is located and it is starting to annoy me so can anyone help me out and tell me where it is or post a pic and show me i would appreciate it thanks!

Its on the passenger side of the block, kinda like half way down and more towards the front. It has a big rubber cover on it, like an inch diameter. Feel around for it. The wire connection on those does go bad and it makes the oil pressure 0, which is scary haha.

Will this do ?

[justin1642]

ok and thanks for the pic. i'll have to see if its connected or it just went bad. cuz it reads 0 and has been like that since i had the motor swapped in.

I swaped my old motor for a motor from japan. I put the sensor off the old one on the japan engine and it worked before but not now. whats the problem. I looked in my manual and i cant find anything on how to test the sensor. can someone tell me how

Anyone, anyone, come on don't be shy.

Same thing happened to mine after I replaced my engine with a used one from Japan. I noticed right after that my oil pressure reading was completely dead. First I changed out the oil pressure sensor with one I bought here in America and noticed the one that was on the engine looked very slim compared to the one I just purchased. After changing it out my gauge still didn't give any readings...turns out the gauge was mechanically dislodged from the needle. Hard to describe without pictures, but I just had to mechanically reconnect the spring to the needle or replace it with a working one I got from the junk yard. I decided to replace it just in case it was more than mechanical failure. Then everything worked perfectly after that. Well here's my guess...not sure if the readout on JDM supra gauges is PSI or N/mm^2 but if it is the N/mm^2 maybe the oil pressure sensor is calibrated for that kind of readout and as result dislodges itself from the gauge needle that reads PSI. Then your gauge is no longer in working condition. Then again you said you swapped your old oil pressure sensor and put it on the new motor. In my case I didn't.

Thats probably what happend to mine because I hooked up the old on for like 1 week and i thought that it would eventually start working. Then the next weekend i switched it out and nothing worked. So pretty much all i have to do is replace the guage and it should start working.

I'm sure if you look at the gauge you can figure out how easily you can put the needle back on the spring so it'll work again. Taking the dash out isn't that hard, just don't rush when doing it...you might snap the black molding that goes above the gauges.

well i worked on it and i the oil pressure guage is getting stuck on 40 I took it off got it unstuck pluged the guages back in and i got stuck again so i will have to replace it, but now i have more problems the turn signals dont work and the speedometer it off of the actual mph im goin I guess i opened a can of worms ill work on it more 2morrow. when you put the guage panel how do you make it to where the MPH guage stays at O mph, when i put it in it fell all the way down to the bottom out spot like below O how do i kept it up to O as im putting the cluster back in.
