Oil Pressure Inspection
WARNING: This page is about a different car, the 2017 Mazda CX-9. However, it is still accessible from the selected car via links, so may be relevant.
- Connect the M-MDS to the DLC-2.
- Start the engine and warm it up.
- Select the engine hydraulic pressure (PID: EOP) and the engine speed (PID: RPM) using the M-MDS data monitor function.
- Verify the engine hydraulic pressure (PID: EOP) value while the engine maintains a constant speed.
- If not within the specification, determine the malfunctioning location referring to the following DTCs "Possible Cause" and repair or replace the applicable part.
- P0524:00 (Engine oil pressure too low)
- P06DD:00 (Engine oil pressure switch control circuit high input)
- P06DE:00 (Engine oil pressure switch control circuit low input)
NOTE:- The oil pressure can vary with oil viscosity, temperature, and engine speed.
Oil pressure (reference value) [oil temperature: 80-90 °C {176-194 °F}, coolant temperature: 80-90 °C {176-194 °F}]
Lo: 135-165 kPa {1.38-1.68 kgf/cm2, 19.6-23.9 psi} [1, 500 rpm]
Hi: 225-275 kPa {2.30-2.80 kgf/cm2, 32.7-39.8 psi} [4, 500 rpm]
- If not within the specification, determine the malfunctioning location referring to the following DTCs "Possible Cause" and repair or replace the applicable part.
