I have a JDM motor and replaced the oil pressure sensor with the USDM sender unit. I hooked it up but i'm reading no oil pressure? Any thoughts?
Nick M said:These are your choices
1. no oil pressure
2. the sending unit doesnt work
3. wiring
4. the gauge doesnt work.
Use a mechanical tester and make sure you have oil pressure. If you run the car all the time, then that isnt it. Obviously.
If you are reading zero or very low, gauge may not work. Unplug the sensor when running, ground it, and ground it with a test light. If the gauge responds to the different inputs, get a new sending unit.
