DTC P2264: Water in Fuel Sensor Circuit Malfunction

NOTE
Conditions for applying fault finding procedures to stored faults:
The fault is declared present after the engine is started or following a road test.
Wiring Diagram
For wiring circuit and connector number, refer to "A-5 Engine and A/C Control System Circuit Diagram (DSL): in
Section 9A".
Troubleshooting
NOTE
If the level of water in the fuel filter unit is lower than the electrodes on the sensor, certain driving
conditions (on a bend, leaning) may cause the injection fault warning light to light up erratically.
1. Check the conformity and quality of the fuel.
2. Check the sealing of the reservoir and the low pressure circuit by applying fault finding-Tests Test 2 referring
to "Test 2: Low pressure circuit check: ".
a. Make sure the water in fuel filter water detection sensor is properly connected.
– If not, clear the fault.
– Carry out a road test (speed > 20 km/h (12 mph) and engine speed > 1200 rpm) for more than 30
seconds.
– If the fault does not recur, end the fault finding procedure.
– If the fault does recur, go to next step.
b. If the sensor is properly connected:
– Drain the fuel filter unit.
– Clear the fault.
– Carry out a road test (speed > 20 km/h (12 mph) and engine speed > 1200 rpm) for more than 30
seconds.
– If the fault does not reappear, finish the fault finding procedure.
c. If the fault recurs:
Check for continuity and the absence of interference resistance on the connection between:
– Between "C82-1" wire of water detection sensor connector and "C85-13" terminal of ECM connector
3. Check the power supply to the water detection sensor:
– Between "C82-3" wire of water detection sensor connector and "E33-6" wire of main relay mounting
connector
– Between "C82-2" wire of water detection sensor connector and vehicle body ground
Carry out the necessary repairs.
If all these checks reveal no irregularities:
• Replace the water detection sensor including fuel filter case.
• Clear the fault.
• Carry out a road test (speed > 20 km/h (12 mph) and engine speed > of 1200 rpm) for more than 30 seconds,
to confirm the repair.
