P2665 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P2665 can be defined as Fuel Shutoff Valve “B” Control Circuit/Open. This error code starts appearing when there is an issue with the fuel shutoff valve. Within the fuel shutoff valve circuitry, a circuit can be displayed as either “open” or “closed”. A circuit would be “closed” when it would be in its normal state and in good working order. If the circuit would be “open”, then there is a disconnection within the circuit. An “open” circuit would be indicated by the P2665 code.

The fuel shutoff valve “B” control circuit is being monitored by the engine control module. This trouble code would be set by the ECM when the fuel shutoff valve “B” control 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 Fuel Shutoff Valve “B” Control Circuit/Open?

• Some flaws in the fuel shutoff valve 'B'
• Fuel shutoff valve 'B' harness might be opened or sometimes shorted
• Fuel shutoff valve 'B' circuit might have inadequate electrical connection
• Faulty powertrain control module

1. 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.
2. 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!
3. 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).
4. Fuel Injector - If there is a leakage in the fuel injectors, then it might cause a rise in the fuel consumption, fuel odours around the vehicle and hard starting. You can always rely on us as we have best auto parts for our customers.
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 the 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 an 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 the mechanic has to check the wires, connectors and other electrical components and quickly replace them if he finds them to be damaged or defective.
• Check for the damaged fuel shutoff valve B and its components for error. It the mechanic finds the fault in the connectors in relation to the fuel shutoff valve B, replace it immediately.
• Also check for the particular battery cells emitting high voltages and thus might need battery replacement as well.
• Parts or components should not be replaced with reference to only a P2665 DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.
• If all the components seems to work perfectly, inspect the PCM for faults and replacement along with reprogramming.

Common Mistakes When Diagnosing The P2665 Code

• Common mistakes while diagnosing this trouble code are unnecessary and expensive replacements which usually happens when one doesn't follow all the steps carefully.
• The most common mistake while diagnosing this code is missing out on diagnosing steps which further leads to the expensive and unnecessary replacements. It is always recommended to seek the help of experienced diagnostician to avoid any mistakes.
