I have the RT oil pressure sensor wired to the Dash2 as per the manual.
Red=5V, Black=Ground, White=Signal
On the Dash2 it reads 10bar (using the metric stock calibration) no matter what the engine is doing (or not doing).
If I use a meter, the white wire reads close to the same 5V reference voltage. Plugging that voltage into the equation gives a reading of about 10bar. So it must be a bad sensor or a bad cable.
As far as I can tell, there is no resistor in this cable as it is a 3 wire sensor. Getting at the sensor end to check the wiring will be quite a lot of work.
Any thoughts before I disassemble half my engine bay?
Thanks
Peter
