Error Code P268A: What It Means & What To Do?

<<See All OBD Codes

See the error code P268A flashing? Don’t worry, with Parts Avatar by your side everything is easy! This OBD-II code decreased engine performance is described as a fuel injector calibration not learned/programmed. One can notice the calibration numbers that are being printed on the side of the fuel injectors. Also, it is essential to enter the new calibration number into the engine computer (PCM) and glow plug control module (GPCM) when the injectors are replaced. The code is set whenever the calibration ID is not registered in both modules.

In the engine control module (ECM), one can find the control functions for the fuel injection system. The memory of ECM and the glow plug control module (GPCM) have every injector’ flow rate information and cylinder position stored. It should be noted that the fuel injector flow rate programming should only be done after the following procedures are performed: the replacement of either the engine control module, glow plug control module or the fuel injectors. The flow rate information can be restored from the glow plug control module (GPCM), if in case the ECM fails to communicate. Also, when both the control modules fail to respond, the fuel injector flow rate information, or injection quantity adjustment (IQA) flow rate numbers should be restored from each individual injector.

What causes this problem with the Fuel Injector Calibration Not Learned/Programmed ?

• Concerns related to the fuel injector flow rate programming

1. Fuel Injector - Fuel injectors present are responsible for injecting the right amount of fuel in the engine. So a damaged one should instantly be replaced. Don’t know where to look for? Parts Avatar provides superior quality fuel injectors just at the prices you have been looking for.
2. Glow Plug - Are you facing difficulty in starting the vehicle? Well, most probably it is caused due to a defective glow plug. We advise you to get your glow plugs restored or repaired immediately.
3. Powertrain Control Module - Abbreviated PCM; this is an integral control unit. So a defective one should be changed immediately as it directly affects the functioning of the entire system. Tune into Parts Avatar for the best PCMs as soon as possible.
4. Engine Control Module - Low acceleration? An illuminated check engine light? Yes, all this is indicative of a defective engine control module. A defective one should be changed or repaired instantly.
5. Fuel Injection System - The fuel injection system is essential for maintaining an optimum functioning of the system. So the ones that are faulty should be changed in order to avoid further expensive after repairs.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD code P268A here:

Common Symptoms

• Diminished engine performance
• A no-start condition

Here are some ways with the help of which you will be able to correct the OBD code P268A:

• Make sure you check the fuel injector flow rate programming. Amendments should be performed as per the requirements
• A malfunctioning powertrain control module should be repaired or replaced
• Repair or replace all the weary glow plugs
• Also, a defective engine control module or fuel injectors should be mended or restored

All the fuel injection system parts should be inspected. Repair or replace all the damaged ones

There is no need to be anxious as Parts Avatar – Car Parts Online is here to help you out! We have high grade fuel injector, glow plug, PCM, engine control module, fuel injection system, injector’s flow and a lot more for our precious customers.

Here we have listed how you can simply diagnose the error code P268A:

A scanner (or code reader) and a digital volt/ohmmeter will be helpful in precisely diagnosing this code-storing condition. Begin your diagnosis with a visual inspection of system wiring, connectors, and components. Repair or replace any open, shorted, damaged, or corroded items as required and retest the system to make sure that repairs were successful. If the system wiring, connectors, and components appear to be in conventional working order, connect the scanner to the diagnostic connector and record all stored trouble codes and freeze frame data. This information can be highly important in diagnosing intermittent conditions that may have stimulated the code being stored. After the codes are retested, operate the vehicle to see if the code returns. If the code fails to immediately return, you may have an intermittent condition.

Common Mistakes When Diagnosing the P268A Code

• Here we have listed a few common mistakes that should be avoided while performing the diagnosis:
• A failed attempt to program (link) the fuel injectors to the powertrain control module and the glow plug control module (GPCM).
