150 Psi Pressure Transducer/Sender/Sensor with Connector Harness 150/200 Psi Stainless Steel 1/8”-27 NPT Pressure Transducer Sensor Compatible With Oil, Fuel, Air, Water

Like many folks who’ve bought the sensor + gauge combo that aem sells, my sensor went bad after only like a year of use. This works seamlessly with the gauge that comes in that kit and is basically half as much as the aem version. Will update this review after a few months/year to see if it outlasts the proper sensor.

I have an Acura RSX Type-S, and I wanted to get oil pressure data from the engine and pass it to my K-Pro ECU. This sensor was what I chose to measure this. The cable pigtail was actually really nice, so I don't feel weird putting it in a place that might get wet. The sensor read oil pressure great! I ordered a second one to use for coolant system pressure readings.My application is different because I'm sending the analog sensor data to the ECU instead of a physical guage. It worked great for this. It's reasonably priced and did what I needed it to do.The other guys are correct:Red = +5V (to Sensor 5V Voltage Source on ECU)Black = Ground (to Sensor Ground on ECU)Green = Analog Signal (to K-Pro Analog Input)

Works with AEM X-Series 150psi oil pressure gauge. Plug and play. The sensor that came with the gauge always read high. Even when the car was off the gauge read 15-20 PSI when it should be 0. Purchased this sensor and now the pressure is accurate. Simple sensor swap, no need to do any wiring. Only been a day but so far so good. Hoping this sensor lasts.

Out of the 4 sensor I ordered, 1 was bad. Will update how long they last on a high HP Haltech 4 cylinder.

The 0-150 psi transducer on my Autometer oil pressure gauge stopped working after about 3 years. The replacement transducer from Autometer is over $150. I figured I would give this much cheaper version a try, and if it didn't work, not much money wasted. I installed it and it works fine. Pictures show the gauge I'm using and the original Autometer transducer I replaced with the Autex one. As I'm writing this review the day after installing it, no word on durability yet.**UPDATE 19-Dec-2022**This replacement sensor is still working fine for me after nearly 1 year of being installed. I also agree with the other review - follow the wiring guide printed on the sensor - NOT the one listed above in the instructions. BLACK = GROUND, RED = 5V POWER, GREEN = PRESSURE SIGNAL.

Well built overall. The cable is durable and shielded. Some reviews complain about accuracy, but the trick is to calibrate, which you can’t do in an OEM environment. I have a few of these and the voltage at rest (no pressure) and the voltage with max pressure vary between them all. You need to compensate for the difference in your code. Non of mine read 5V at 150psi +, so naturally the accuracy can go from +/- .5psi to +/- 15psi

1 star for the item because I think it is defective. I contacted the seller about the analog output is not correct even though the supply voltage is stable at 5VDC. The output will only register if I push the cable connector where it interfaced with the metal portion of the pressure sensor. It almost seems like there is something loose in there. I have not tried to open it myself but checking with the seller if it can be replaced. I passed my 30 days return window so I am hoping they are kind enough to allow me to get a replacement sensor and I can return this one.

Used this product to replace my defective ProEFI Oil and Fuel pressure sensors used on my 1994 Supra 2JZ-GTE using a ProEFI engine management system. The ProEFI 150 psi sensor replacement from a performance shop is 3 times the cost and have had 2 failures in the past. The Autex specs matched the ProEFI and I did not have to modify calibration settings after replacement. Awesome. Going to buy another sensor for a spare.
