P2264 - OBD Trouble Code

<<See All OBD Codes

The trouble code P2264 can be defined as Water in Fuel Sensor Circuit. It is a generic code for the engine control module which detects the water in fuel sensor circuit voltage falling below or exceeding the specified limits.

The water in fuel sensor circuit is being monitored by the engine control module. This trouble code would be set by the ECM when the water in fuel sensor circuit would not be as per the specifications set by the manufacturer. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

What causes this problem with the Water in Fuel Sensor Circuit?

• Malfunctioning water in fuel sensor
• Polluted fuel
• Faulty fuse or fuse-able link
• There can be inoperative or worn fuel filter
• Corroded or damaged connector
• Some issues related to the wiring
• Unusable ECU

1. Fuel Pressure Regulator - Faulty fuel pressure regulator can lead to black smoke emitting from the tailpipe along with fuel leaks from tailpipe, engine not running smoothly and stalling, and problems to the transmission system. Thus, replace it now!
2. Engine Control Module - There can be some engine performance issues due to faulty engine control module. If the ECM fails or has any problems it can lead to performance issues with the vehicle like misfires, hesitation, loss of power, and sometimes even decreased fuel economy.
3. Fuel Sender Connector - The fuel sender connector is responsible for optimizing the fuel flow into the engine and if found faulty, will cause problems in fuel delivery. Thus, it needs to be replaced immediately.
4. Powertrain Control Module - PCM stands for powertrain control module. It is a car part, a control unit which is utilized on motor vehicles. It is generally a combined control unit, consisting of the engine control unit (ECU) and the transmission control unit (TCU).
5. Electronic Control Unit - If your automobile's check engine light remains on constantly, and never goes off, there's a good chance that your vehicle has a damaged electronic control unit. There are a lot of reasons why a car's check engine light will remain on. The most common reason is a defective ECU.
6. Diagnostic Tools - It is always advisable to use correct tools and equipment while resolving any OBD code issue as even small mistakes can lead to wrong diagnosis. Thus, always take help from a professional who has the knowledge and experience to such tools in efficient manner. Buy new quality diagnostic tools from us today!

Here are some steps which you should follow in order to diagnose this fault code:

This is a general type of error code which is diagnosed with the help of a scanner. The mechanic will insert a scanner to diagnostic port of the vehicle and recover the codes and freeze frame data. If he happens to find any additional error codes, he has to address them as well. Once it is done, he has to reset the vehicle, and then test drive to see if the error code appears. If the error code does not return, then there can be an erratic condition. Then after that the next step would be to inspect the records of the automobile to check when the fuel filter was restored and then the condition of the filter should be visually inspected. This error code is generally caused due to faulty fuel filter or contaminated fuel. Utilize a glass jar to perform the visual inspection of the fuel. Now once the sample has been taken, it is essential to allow it to settle down and then the fuel would separate in a matter of minutes. If water is present in the fuel, then it would indicate that the fuel is contaminated, a faulty fuel filter or there might be both of them. Then the mechanic should find all the constituents in the water in fuel circuit and perform a thorough visual inspection to inspect the related wiring for obvious defects such as scraping, rubbing, bare wires, or burn spots. After that examine the connectors for security, corrosion and damaged pins. The sensor is generally mounted on the top of the fuel tank on many automobiles.

Here are some advanced steps

The advanced steps become very automobile specific and need the appropriate advanced equipment to perform correctly. A digital multi meter and the particular technical references for the vehicle would be needed to carry out these procedures. The tool which would be perfect to utilize in this particular situation is an oscilloscope. The O-scope will provide a correct illustration of the signal pulses and the frequency levels that will be proportional to the fuel contamination level. The typical range of frequency is from 50 to 150 hertz; with 50 hertz which represents clean fuel and 150 Hertz represents a high level of contamination. Voltage needs as well as signal pulses will differ depending on the particular year and model of the automobile.

Here are some voltage checks

The water in fuel sensor is generally supplied with a voltage reference of approximately 5-volts from the powertrain control module. If this process identifies the lack of a power source or ground, then there would be a need of continuity testing to inspect the integrity of the wiring, connectors as well as other constituents. Make sure to remove the power from the circuit and the normal readings for wiring and connections should be 0 ohms of resistance while performing continuity tests. Resistance or no continuity would indicate defective wiring that is opened or shorted and it should be repaired or restored carefully.

Common Mistakes When Diagnosing The P2264 Code

• A big mistake made by a lot of people is to replace the PCM or water in fuel sensor when faulty wiring or contaminated fuel is the real cause of the issue.
• Mistake of clearing ECM memory codes before inspecting the freeze frame data is generally made by a lot of mechanics.
• Most of the mechanics fail to clear the ECM codes after the repairs are done
• A lot of technicians might fail to verify the fuel is not contaminated before replacing the water in fuel sensor.
