Engine Oil Pressure






Oil Pressure

If the LED does not light up:

- Start the engine and increase the RPM: the LED must come on at 1.2 to 1.6 bar pressure; if not, then replace the oil pressure switch.

- Increase engine speed further. At 2000 RPM and an oil temperature of 80 degrees C (176 degrees F), the oil pressure must be between 2.7 and 4.5 bar.

At higher engine speeds oil pressure must not exceed 7.0 bar
