■Engine oil pressure gauge
The engine oil pressure gauge displays the engine oil pressure from 0 to 800
kPa. The rapid response of the TFT LCD panel allows for the fluctuations in engine
oil pressure that occur with engine speed to be displayed instantly. The engine oil
pressure is also affected by other factors such as engine oil type, temperature and
deterioration. If the engine oil pressure is too low, the master warning light comes on
and the “Engine oil pressure low” warning message is displayed. Checking the engine
oil pressure regularly aids understanding of the condition of the engine and engine oil.
During high-speed driving: approximately 400
to 800 kPa
(changes depending on driving conditions)
[Outside air temperature approximately 68°F
(20°C)]
When oil pressure is insufficient
An oil pressure sensor is installed near the oil filter.
The oil pressure measurements are processed by the ECU and displayed by the
engine oil pressure gauge.
