DTC Troubleshooting
| Step | Action | Yes | No |
|---|---|---|---|
| 1 |
Was “Engine and Emission Control System Check” performed?
|
Go to Step 2.
|
|
| 2 |
Fuel filter water detection sensor power supply circuit and ground circuit check
1)When ignition is “OFF”, disconnect fuel filter water detection sensor connector.
2)Check for proper terminal connection to fuel filter water detection sensor connector.
3)If connections are OK, set ignition “ON”.
4)Check that voltage between “A1” and “A3” circuits is battery voltage.
Is check result OK?
|
Go to Step 4.
|
Go to Step 3.
|
| 3 |
Fuel filter water detection sensor ground circuit check
1)Check that voltage between “A1” circuit and ground is battery voltage.
Is check result OK?
|
Repair “A3” circuit.
|
Repair “A1” circuit.
|
| 4 |
Fuel filter water detection sensor signal circuit check
1)When ignition is “OFF”, disconnect “E01” connector from ECM.
2)Check for proper terminal connection to “E01” connector.
3)If connections are OK, check the following points.
•Resistance of “A2” circuit: less than 1 Ω
•Resistance between “A2” circuit and ground: infinity •Resistance between “A2” circuit terminal and other terminal at fuel filter water detection sensor connector: infinity •Voltage of “A2” circuit: approx. 0 V (When ignition is “ON”) Is check result OK?
|
Go to Step 5.
|
Repair or replace defective wire harness.

Fuel filter water detection sensor replacement
1)Replace fuel filter assembly.
2)Clear DTC.
3)Set ignition “OFF”.
4)Check DTC.
Is DTC P2264 is still detected?
|
Replace ECM and recheck DTC.
