low oil pressure truck runs good

[davig]

How do you test the sensor and wiring?

 

[MMLMM]

Check the sensor with a DMM. The range is 0-90ish Ohms.

1 Ohm = 0 psi
88 Ohm = 80 psi

Check it and verify with mechanical gauge.

You just in plug the sensor and do it from there wile the truck is running?

I checked the sensor and it seems to be good I noticed my pressure reads 11 psi instead of the 14 psi spec.
