Richard Hainsworth Posted September 17, 2015 Report Share Posted September 17, 2015 Hi all, have noticed another slight issue with my setup, its a g3/4 (upgraded yesterday) and am running a honeywell 150psi oil pressure sensor, with key on engine off sensor is at 0.88 volts, this shows up as 14.3 psi or 143kpa, what would cause this? is it a faulty sensor? I'm running the 150psi ti sensor calibration.not ideal really as it should show 0psi i would think?CheersRichard Quote Link to comment Share on other sites More sharing options...
Dave Kriedeman Posted September 17, 2015 Report Share Posted September 17, 2015 Hi Richard,I am not sure how similar the TI (TEXAS INSTRUMENTS) OIL PRESSURE sensor 150 psi calibration is compared to HONEYWELL 150 psi calibration.So you have 5 volts reference going to the sensorSensor signal is going to an Analogue volt inputSensor negative is going to sensor ground NOT EARTHIf you have terminated the sensor as above then I would be checking the calibration values.RegardsDave.

Richard Hainsworth Posted October 1, 2015 Author Report Share Posted October 1, 2015 sorted the issue, i have an absolute pressure sensor so .88v = 0psi, made a custom cal and use that and its perfect.Richard Quote Link to comment Share on other sites More sharing options...
