P2264 to P2269: water in fuel sensor and water detected

The sensor in a diesel's fuel filter that detects water has a circuit fault or an implausible, low, high or intermittent signal, or it has detected water in the fuel (P2269).

SeverityModerateUsually not urgent today, but it can get worse if left.

What does P2264 mean?

Diesel fuel can carry water, from condensation in the tank or from a bad fill-up, and water damages the precise parts of a high pressure pump and injectors. The fuel filter collects it at the bottom, and a sensor there warns when it needs draining. P2269 means the water level has reached the sensor, so the filter needs draining now; the sensor codes mean the warning can no longer be trusted, so the filter should be drained regularly until it is fixed.

What causes P2264?

  1. Water in the fuel from condensation or a bad fill-up
  2. A fuel filter that has not been drained or changed for a long time
  3. A failed water sensor in the filter housing
  4. A damaged wire or corroded connector at the filter

What to check first for P2264

  • Drain the water from the fuel filter as the owner's manual describes
  • Think back to the last fill-up and where it was
  • Check whether the fuel filter is due, since water shortens its life
  • Inspect the sensor's connector at the bottom of the filter

Can you drive with P2264?

With P2269, drain the filter before driving further, or have it done; if the engine runs rough or loses power, stop, because water can damage the injection pump. With only a sensor code, you can drive to a workshop.

Since May 2018 an engine warning light that stays on is a major defect at the MOT, so the car fails until the fault is fixed.

These are the generic meanings every manufacturer shares. Each brand adds its own detail, so your car's handbook, its service information and a qualified mechanic have the last word. OdoKeep has no connection with any manufacturer, and the app does not read codes from the car.

Write the code into the car's history

Log the code in OdoKeep as an OBD scan when a scanner or the workshop gives you one, then the repair and what it cost, and keep the maintenance that prevents it on a plan with reminders. The app keeps the record; it does not read the car.
