DTC P2265
Diagnostic Instructions
DTC Descriptor
| DTC P2265: Water in Fuel Sensor Circuit
Malfunction |
Circuit/System Description
The water in fuel sensor is located in the bottom of the fuel
filter housing. The engine control module (ECM) monitors the water
in fuel sensor signal circuit for a predetermined voltage.
Conditions for Running the DTC
| • |
The DTC runs continuously once
the above condition is met. |
Conditions for Setting the DTC
The ECM detects an incorrect water in fuel sensor signal for
more than 0.7 s.
Action Taken When the DTC Sets
DTC P2265 is a Type C DTC.
Conditions for Clearing the DTC
DTC P2265 is a Type C DTC.

Circuit/System Verification
| 1. |
Engine running, observe the
DTC information with a scan tool. DTC P2265 should not set.
|
| 2. |
Operate the vehicle within the
Conditions for Running the DTC to verify the DTC does not reset.
You may also operate the vehicle within the conditions that you
observed from the Freeze Frame/Failure Records data. |
Circuit/System Testing
| 1. |
Ignition OFF, disconnect the
harness connector at the B116 Water in Fuel Sensor. |
| 2. |
Test for less than 5 Ω
of resistance between the ground circuit terminal 2 and
ground. |
| ⇒ |
If greater than the specified range, repair the
ground circuit for an open/high resistance. |
| 3. |
Ignition ON, verify that a
test lamp illuminates between the ignition voltage circuit terminal
1 and ground. |
| ⇒ |
If the test lamp does not illuminate, test the
ignition voltage circuit for a short to ground or an open/high
resistance. If the circuit tests normal and the fuse is open, test
all the components connected to the ignition voltage circuit and
replace as necessary. |
| 4. |
Verify the scan tool Water in
Fuel Sensor parameter displays Inactive. |
| ⇒ |
If the parameter displays Active, test the signal
circuit for a short to ground. If the circuit tests normal, replace
the K20 Engine Control Module. |
|
Caution: If
the fuse in the jumper wire opens, the signal circuit may have a
short to a voltage or a short to ground and the sensor might be
damaged. |
| 5. |
Install an 1 A fused jumper
wire between the signal circuit terminal 3 and ground. Verify the
scan tool Water in Fuel Sensor parameter displays Active.
|
| ⇒ |
If the parameter displays Inactive, test the
signal circuit for a short to voltage, or an open/high resistance.
If the circuit tests normal, replace the K20 Engine Control
Module. |
| 6. |
If all circuits test normal,
replace the B116 Water in Fuel Sensor. |
Repair Instructions
Perform the
Diagnostic Repair Verification after completing the diagnostic
procedure.
