Title: Problem with 0-150psi sensor calibration
Post by: TC-Tuned on September 10, 2016, 04:14:55 PM
I have a 0-150psi 0.5v to 4.5 pressure transducer but i can't get to display correct info on oil or fuel pressure, when the car is not running it says it has -9 psi fuel pressure

these are the settings

that means min voltage is not 0.5 :))

it means with no pressure, when engine is not running sensor is giving not 0.5v but maybe 0.2v or similar ;)

Many sensors have a reading range of 0.5-4.5v

0 = 0psi
4.5v = X psi

Did you solve your issue?
Was that a Bosch 2 wire pressure sensor?
