P2149 - OBD Trouble Code

Your vehicle's fuel delivery system monitors and controls the volume, timings and pressure by using different components. These are used in connection with the Engine Control Module. Fuel injectors were introduced in vehicles because they are better and effective in controlling fuel delivery as per need of the vehicle. They hence substituted the carburetors.

Here are some steps which you should follow in order to diagnose the P2149 fault code:

 

Start your diagnosis by visually inspecting all the wiring and connectors associated with this issue. You will have to either repair or replace all the damaged wiring and connectors, these could range from disconnected, shorted, burned or corroded wiring. Components that may have gotten damaged also will have to be repaired or replaced.

 

Clear the codes and retest the system by going on a test drive. Re-testing the system helps in knowing if the repairs were a success. If the electrical components and wiring are all in good condition then connect the scanner to the diagnostic port of your vehicle and retrieve all the codes stored and freeze frame the data. Freeze framing is very important as it helps in diagnosing intermittent conditions that may have caused this code to be stored by the PCM.

 

If the code doesn’t return then you’re facing an intermittent condition, if the code sets then you have to check the PCM for any repairs or replace it. Replacing the PCM requires programming, hence it is important to approach a professional for the same.
