 Water-In-Fuel (WIF) Sensor Circuit
|
Circuit Description
The water-in-fuel sensor is attached to the fuel filter. The water-in-fuel sensor sends a signal to the electronic control module (ECM) when a set volume of water has accumulated in the fuel filter. The water-in-fuel circuit contains two wires: A return ground (pin 10) and a signal wire (pin 9).
Component Location
The water-in-fuel sensor is installed in the fuel filter and is located on the side of the head approximately midengine.
Shop Talk
The water-in-fuel sensor uses the same internal ECM power supply as sensors on engine harness. If Fault Code 352 is also active, use that troubleshooting logic and tree.
Refer to Troubleshooting Fault Code t05-429.
