- 2017 CX3 AWD
Mazda was so confident with the CX-3 that they felt no need to display the engine oil pressure/temp and coolant temp on the dashboard. 
I have to get the values from an OBDII device/app.
I have tried a few apps but none is showing the oil pressure. The closest item I get is the "oil pressure solenoid valve: open." It is mostly 1 (open) and sometimes 0 (closed). Does anyone know under what circumstances it should be open/closed? I glanced over occasionally and saw that it was 0 when going uphill. It doesn't seem to be directly related to the speed, rpm, or engine load. Wondering if this sensor/value is useful in gauging the engine's health at all.
