Circuit/System Description

WARNING: This page is about a different variant/trim than selected.

The Water In Fuel Sensor monitors for the presence of water in the fuel. When water is present, the Engine Control Module (ECM) detects low voltage on the signal circuit and sends a request to the instrument panel cluster via the CAN communication circuit to display the WATER IN FUEL message.
