Holley EFIWill the OEM sensor work with the Holley? It plugged in fine with my harness. I haven't tried it yet just wondering if it's gonna work, or if I need to order another sensor. Engine is a 5.3L LS.

OEM Oil Pressure Sensor

Yes, select "Custom Pressure" (in Sensors), and enter the OEM "Calibration Curve" (0-5V & PSI data).Originally Posted by ButchB

Any idea on where I could find the calibration curve for the stock sensor? I've done a search for it, and all it came up with is "oil psi is -16.5 at 0, and 150 at 5V", but not sure how accurate that is.

Acquiring that sensor calibration data is your responsibility. The LSx engine is one of the most popular hot rod engines in existence...surely the information is out there somewhere.

To anyone else looking, I found the following on YellowBullet.com.
LS1 oil pressure:
0.5V = 0 psi
4.5V = 130 psi

I knew you'd find it. It's an LSx engine...the information is available.
May God's grace bless you in the Lord Jesus Christ.

I started my car tonight, and the oil pressure is saying 130 psi. Either that info I found is wrong, or maybe the pin-out is different on the wiring?
Administrator
I think the pin-out is the same as OEM.
Pin A - sensor ground
Pin B - +5 volts
Pin C - signal
Cavity A=1, B=2, C=3

Thanks Danny. I'm gonna try another sensor, I'm hoping it's just a bad sensor.

This is an old thread, but I wanted to add a pic of the way the scale should look for a stock GM oil pressure sensor. I'm using an ACDelco Oil Pressure Sensor, part D1846A. The curve will look like this. Get it set that way with this sensor and you'll be good to go.
