Water in Fuel Alarm / Limp Mode.
Variant 1
System
Fuel (Water)
Symptom
Water in Fuel Alarm / Limp Mode.
Diagnosis & fix steps
LOGIC: Water-in-Fuel (WIF) sensor resistance low.
ACTION: Drain the primary fuel filter bowl. If the light stays on after draining, check the sensor pins for "green rot" corrosion.
Red Seal field insights
PRO-TIP: In Ontario winters, ice in the bowl can trip this code. Warm the filter with a heat gun to see if the resistance returns to normal before replacing the sensor.
Variant 2
System
Fuel
Symptom
Water in Fuel Light.
Diagnosis & fix steps
LOGIC: Conductivity probe in the water separator detects water.
ACTION: Drain the primary fuel filter bowl immediately.
Red Seal field insights
PRO-TIP: If the light stays on after draining, the probe is likely "filmed" over with algae. Remove and clean the pins with a scotch-brite pad.
