Fault of oil pressure sensor
415-Engine oil duct pressure-valid but below normal operating range-the highest severity level
Overview
The oil pressure sensor has diaphragms and contacts acting due to oil pressure function inside it. When its oil
pressure is below its specified value, the diaphragm has no acting force to push the spring, its contact will be
closed, and the combination instrument indicator lamp will go on; when its oil pressure is above its specified
value, the diaphragm will push up the spring, its contact will be separated, and its indicator lamp will go out.
At this time, the driver shall know that its oil pressure has reached the specified value. Under normal
condition, the contact action pressure is at 30~50kPa.
