The Water in Fuel Sensor Circuit fault code indicates that there is an issue with the sensor that detects the presence of water in the fuel system. This is crucial for maintaining the integrity of the fuel and preventing damage to the engine components.

• The water in the fuel can lead to corrosion, reduced combustion efficiency, and potential engine misfires.
• The sensor plays a vital role in signaling the control unit to take action when water levels in the fuel exceed safe limits.

What are the symptoms of the P2264 code?

Common symptoms associated with this fault code may include:

• Engine warning light illuminated on the dashboard.
• Poor engine performance, including misfires or rough idling.
• Difficulty starting the engine, especially during cold weather.
• Fuel odor, indicating possible leaks or contamination.

What causes the P2264 code?

Several factors can lead to triggering the Water in Fuel Sensor Circuit fault code:

• Accumulation of water due to condensation in the fuel tank.
• Contaminated fuel from suppliers with high moisture content.
• A malfunctioning or faulty water sensor that fails to detect water levels accurately.
• Damaged wiring or poor connections in the sensor circuit.

How to fix P2264?

To address the Water in Fuel Sensor Circuit fault code, the following steps should be taken:

• Inspect and potentially replace the water sensor if found faulty.
• Check the wiring and connectors for damage or corrosion, repairing or replacing as necessary.
• Drain any accumulated water from the fuel system and replace any contaminated fuel.
• Reset the fault code and monitor the system for any recurring issues.
