Water In Fuel Sensor Circuit

This warning sign that must be addressed this warning light indication immediately tells you that there is excess water in your diesel fuel.

Water in fuel sensor circuit.

P2264 is an obd ii generic code for the engine control module ecm detecting the water in fuel sensor circuit voltage falling below or exceeding the specified limits. The fuel sensor detects fuel ethanol contamination and provides the engine control module with a fuel temperature. The wif sensor is usually installed in the fuel filter. Water in fuel sensor circuit.

When the power control module pcm detects an out of expected range or other performance problem with the electrical signals within the water in fuel sensor circuit code p2265 will be set and the check engine light. What the p2264 code means. The ecm monitors the water in fuel circuit and has detected the return voltage to be above or below threshold limits for the sensor. If the waveform pulse of the water in fuel fuel composition sensor does not fall within the manufacturer s specifications the sensor should be replaced.

The electronic control module ecm provides a 5 volt reference signal to the water in fuel sensor. If the water in fuel fuel composition sensor continuity resistance and ground circuit tests pass use an oscilloscope to watch the waveform pulse of the sensor. When the power control module pcm detects improper signals within the water in fuel sensor circuit code p2264 will be set and the check engine light will be illuminated. The obd ii trouble code p2264 is associated with the water in fuel sensor circuit also known as the fuel composition circuit.

The water in fuel sensor is attached to the fuel filter. The water should be drained from the filter to prevent. The water in fuel wif sensor monitors water concentration in the fuel and sends a signal to the engine control unit ecu if the water levels are too high. If the sensor detects water in the fuel a check engine light can appear.
