Water in fuel sensor bypass igotacummins is an online forum and community for all cummins turbo diesel enthusiasts. Water is heavier than diesel so in a practical sense you should suffer problems prior to the 50 or 60 gals left in the tank. Recirculated exhaust gas temperature sensor not shown 11. Service network cummins engines are backed by the strength of cummins global network of over 5 500 service locations worldwide.

When the water collected in the fuel filter covers the sensor probes the water in fuel sensor pulls the 5 volt reference voltage to ground indicating high water accumulation in the fuel. When the code for the water in fuel sensor popped up it also triggered an engine coolant temperature code to flash as well. The ecm determines that the voltage in the sensor signal circuit is less than 0 05 v dc for 1 second.

Gauges really helped me out with this one. Intake manifold pressure sensor 7. Isx automotive with cm870 left side view 1. Which means even with condensation from cold fuel pumped in to a hot tank it would separate and slowly fall to the bottom of the tank especially as the movement of diesel would wash it off the sides as the vehicle moves.

The water in fuel sensor is used to indicate high water accumulation in the fuel filter.
