Error Code P269E: What It Means & What To Do?

<<See All OBD Codes

Do you know what are the symptoms and causes of the P269E error code? Are you looking for the diagnostic steps to resolve them? The engine performance which is reduced is known as exhaust aftertreatment glow plug control circuit. Then look no further and keep reading ahead. With the help of the diesel exhaust fluid, the remaining exhaust particles are changed into harmless gas. These exhaust particles can be easily burnt only if the temperature of the exhaust system is very high. The diesel particulate filter DPF will move up to the required temperature when the DEF fluid is injected into the exhaust stream. The dangerous NOx is then converted into nitrogen, carbon dioxide and water by the system.

The DEF will be prevented by the glow plug from freezing during extremely cold temperatures. Failing to operate as requested will lead to the storing of the P269E error code. The PCM looks closely at the exhaust aftertreatment glow plug control circuit. The error code will be set by the PCM if the exhaust aftertreatment glow plug control circuit goes out of the factory specifications.

What causes this problem with the Exhaust Aftertreatment Glow Plug Control Circuit High?

• Defective exhaust aftertreatment glow plug.
• The exhaust aftertreatment glow plug harness might have an opening or short circuit.
• The exhaust aftertreatment glow plug circuit might have a weak electrical connection.

1. Powertrain Control Module – The engine will fail to start or the fuel economy will be poor if the powertrain control module is faulty. Get them replaced as soon as possible so that you can get rid of the P269E error code.
2. Glow Plug – Is fuel efficiency very low? Is the engine performance weak? Then replace your glow plugs quickly as they can be faulty.
3. Shift Solenoid – Erratic shift by the vehicle is an indication of broken shift solenoid. Replace it instantly.
4. Electronic Pressure regulator – The electronic pressure regulator can be faulty if the performance of the engine is low. Get rid of it as soon as possible.
5. Glow Plug Relay – Any damages in the relay can affect the glow plugs. Replace the damaged component as soon as possible.
6. Engine Control Module – Does your car jump start on reverse polarity? It is an indication of damaged ECM. Replace it soon to avoid P269E error and get a new one from PartsAvatar.

If you are facing OBD error code P269E, then there are significant common symptoms that can be felt or observed. We have worked out a list here to help you out in understanding this problem better.

Common Symptoms

• Engine performance seems to be low or diminished.
• No occurrence of DPF generation.
• You might notice the flashing of the engine light and the warning light of the service engine.

It is very important to fix the fault code P269E. So here are some ways with which you can correct this issue:

• Firstly fix every of the defective, separated, shorted, or eroded wires, connectors and components as needed.
• Based on the condition, a sensor which is available on the accelerator pedal arm will input a voltage signal to the PCM as well as its linked controllers which will command the throttle body to be open or closed.
• If the error code does not return quickly, the condition might be erratic.
• Based on the controllers' command, the change in ratio will make the throttle plate to open quickly, suddenly, slowly or casually.
• Start testing the electrical connector of the throttle position sensor.
• As there are huge circuits involved, unlike other codes, leave it to the professionals, as they can handle them.

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of PCM, glow plug, shift solenoid, electronic pressure regulator, glow plug control module, glow plug relay, ECM and many more. Now all your problems would vanish within no time.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• Use a diagnostic scanner, a reliable source of vehicle information, and DVOM to perform correct diagnosis.
• Search for apt TSB that matches your vehicle model, make, stored code to perform diagnosis.
• Also, you can use diagnostic flow charts, wiring diagrams, connector face views, connector pinout charts, component locations, and component testing procedures to diagnose the error code P269E.
• You can connect the scanner to the diagnostic port once you check the glow plug/ wiring/ connectors.
• Recover all codes and freeze frame data.
• Test drive to see if codes recover.
• If the code resets then continue the diagnosis.
• You have to worsen the condition to perform careful diagnosis.
• The best way is to apply battery voltage by removing the glow plugs.
• If the glow plugs are in good condition, activate them and test for battery voltage at the connector.
• Test the fuse and relays while the circuit is loaded. It may appear to function properly but will lead to the wrong path.
• If both the fuses and relays appear functional, test the output voltage with DVOM.
• If the voltage is low there can be an open or shorted circuit which is simple to replace.
• It is sometimes assumed that a P269E cannot be the reason for a defective glow plug as it’s is a control circuit code.
• Sometimes, a bad glow plug will cause a difference in the control circuit that results in just such a code.
• Before you attempt to diagnose the cylinder, make sure that you are proceeding with the right cylinder.

Common Mistakes When Diagnosing the P269E Code

• Faulty glow plug control module.
• Glow plug relay might be malfunctioning.
• Faulty powertrain control module.
• Troublesome electrical wires.
