It's no use just disconnecting the sensors.
The oil level sensor wires need bridging. Red and green to the black. Leave the orange floating.
Remove the oil flow sensor. Dismantle by undoing the four screws/bolts and clean the gauze filter. Ensure the micro switch is open. It should close when the sensor is full of oil. Refit and bleed the oil system by using the bleed screw on the oil pump. Use a fuel/oil mix when doing this as you might be running on neat petrol til you get the air out of the system.
Start engine and press reset button.
If this fails, bridge the water flow sensor wires.
