Circuit Function
The WIF sensor is used to detect water in the fuel system and is located in the fuel conditioning module. The WIF sensor is monitored by the powertrain control module (PCM). If the PCM detects water for more than 4 minutes, it sets continuous DTC P2269 and turns on the WATER IN FUEL indicator lamp.
CAUTION:
The PCM harness connectors must be properly seated and the connector latch properly attached to eliminate possible driveability concerns or a no-start condition. Installing PCM connectors on an angle may cause an improper connection, misdiagnosis, and damaged components. Install the connector until the lever pivots and seats itself. Apply light pressure to get the connector into position on the PCM and then fully seat the connector.
NOTE:
Visually inspect the harness connectors for corrosion, damage, proper mating, and correct pin tension.
