Oil pressure sensor.

Post by gsxr2mil »

I have a 150psi oil pressure sensor and when the bike is running at idle itll read fine and when I rev it up itll drop oil pressure at least that's what the sensor is telling the ecu, it was at 76psi at idle almost and then around 9 psi at 8k rpm so I'm thinking the sensor is faulty. Anyone ever had this problem

sounds like you have the sensor scaling in the software wrong, you need to calibrate the readings from an air line or something else like.

What type of sensor is it? VDO style or pressure transducer?

It's a pressure transducer sensor.

It'll be a Chinese jobbie. An equivalent good sensor would be 0.5v to 4.5v to cover the quoted pressure range.

But rather than guessing, get the supplier to give you a spec sheet, or failing that you'll need to DIY calibrate.

They should be a linear output so relatively easy to calibrate.

I went into the ecu and just cut the switch in when the bike was off and it read 1235v and 27psi of oil pressure I know that couldn't be right.then when I started it the oil pressure drops

you cut the switch in ???? no clue what that means

And it would be impossible for a 5v sensor to read 1235 volts.. like over 1,000 volts ?

It needs calibrated...and maybe wired correctly.

Cut the switch on I mean sorry, and its wired correctly, I believe my sensor is going bad it's a cheap one anyway

Ok just read it, but in order to scale it correctly dont I need to put an oil pressure gauge on it to see where the oil pressure is at that given voltage for the oil pressure sensor?
