Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions provide an overview of each diagnostic category.

DTC Descriptor

DTC P2269
- Water in Fuel

Circuit/System Description

A sensor/switch mounted in the bottom of the fuel filter housing is used to detect water in the fuel. The water in fuel (WIF) sensor/switch has an indicator control circuit and a low reference circuit. The engine control module (ECM) monitors the voltage to the WIF sensor/switch. If the voltage is incorrect, the ECM will illuminate the WIF lamp and set the appropriate DTC.

Conditions for Running the DTC

* The engine is running.
* The diagnostic runs continuously.

Conditions for Setting the DTC

* The engine is running.
* The WIF sensor/switch voltage is less than 0.20 volt for more than 60 seconds.

Action Taken When the DTC Sets

DTC P2269 is Type C DTC.

Conditions for Clearing the DTC

DTC P2269 is Type C DTC.

Diagnostic Aids

* If DTC P2269 sets intermittently, fuel contamination may be the cause. Refer to Contaminants-in-Fuel Diagnosis. Contaminants-in-Fuel Diagnosis
* On vehicle with a WIF float switch, a float sticking may illuminate the WIF lamp and set this DTC.

Circuit/System Verification

* Observe the Water in Fuel Sensor voltage parameter with a scan tool. Voltage should be between 0.20-4.75 volts.
* Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame Records data.

Circuit/System Testing

If any DTCs other than P2269 are set, Refer to Diagnostic Trouble Code (DTC) List - Vehicle. Diagnostic Trouble Code Descriptions

Important: The WIF lamp should be illuminated with this DTC. If the WIF lamp is not illuminated, Refer to Water-in-Fuel Lamp Inoperative.

1. Turn OFF the ignition and drain the fuel filter. Refer to Water-in-Fuel Draining.
2. Turn ON the ignition and clear the DTC.
3. Start and run the engine.

• If this DTC resets, test for fuel contamination. Refer to Contaminants-in-Fuel Diagnosis. Contaminants-in-Fuel Diagnosis
