Oil pressure depends on the engine revolution. Power is reduced due to error torque map if engine protection parameter is At a threshold resistance (water has been detected), the switch output signal (yellow cable) to the engine control unit pin B8 will be pulled down to zero.įMI 1 – Data valid but below operational range If there is any water in the fuel, the resistance falls. When there is no water in the fuel, the resistance is very high. The switch senses the resistance between two pins, wich are in contact with the fuel. Its task is to detect whether there is water in the fuel. The cable connected to B8 is short circuited to battery negative.ġ Check cable harness and connectors between water in fuel monitor andĪ switch is located in the water trap under the fuel filter.Short circuit between both cables to the water in fuel switch.Checking negative cable, water in fuel switch page 118įMI 4 – Voltage below normal or short circuit to lower voltage.Checking supply cable, water in fuel switch page 118.The cable connected to B8 is short circuited to battery voltage.ġ Check cable harness and connectors between water in fuel switch and Water in the fuel trap has been detected.įMI 3 – Voltage above normal or short circuit to higher voltage FMI 0 – Data valid but above normal operational range
