Jo LeForce Posted January 15, 2019 Report Share Posted January 15, 2019 I'm using a couple of new HoneyWell 1000kpa pressure sensors for fuel & oil pressure, connected to AN2 & AN8, calibrated as 1000kpa (150psi) TI sensor. The problem is that at idle the sensors fluctuate around 40 kpa but once throttle is applied the reading rapidly drops to zero rather than increasing! Any clues what the problem is, wiring, polarity? Thank you Quote Link to comment Share on other sites More sharing options...
ClintBHP Posted January 15, 2019 Report Share Posted January 15, 2019 Ground and +5v wired the wrong way around maybe, but I actually though they had red and black wires for feed so I would hope you got that correct, could be the calibration you will need to use CAL 4, 5 or 6 and set it like this: Quote Link to comment Share on other sites More sharing options...
cj Posted January 16, 2019 Report Share Posted January 16, 2019 Both of them drop at the same rate or are they different? Does the engine start to stall like its actually running out of fuel? Maybe post a log. For the fuel one I'd check you dont have the regulator physically plumbed in to the wrong ports but this wouldnt explain the oil sensor or if the engine feels fine. Do the readings you are getting at idle look sensible in the first place? Quote Link to comment Share on other sites More sharing options...
