P269B OBD Error Code: Problem & Solutions

<<See All OBD Codes

Are you looking for information with respect to exhaust aftertreatment glow plug control circuit/open? Then you are at the right place and keep reading ahead to gather more information. The exhaust particles in the vehicle are converted to gas which is harmless and is assisted by the DEF. the temperature must be increased to burn these remaining exhaust particles. The exhaust stream will bring the DPF up to the needed temperature when the DEF is injected into it, where the dangerous NOx in the system is then converted into nitrogen, carbon dioxide, and water.

During extreme cold conditions, the glow plug will keep the DEF from freezing. The error code will be set by the PCM exhaust aftertreatment glow plug control circuit fails to meet the necessary factory specifications.

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

• Damaged exhaust aftertreatment glow plug.
• There might be an opening or the exhaust aftertreatment glow plug harness might have a short circuit.
• The electrical connection of the exhaust aftertreatment glow plug circuit might be weak.

1. Powertrain Control Module – The PCM regulates important functions of the vehicle as well as it has a direct impact on how well your vehicle performs. Fixing your faulty powertrain control module (PCM) will help your engine to run smoothly
2. Glow Plug – There will be power loss if the glow plugs are broken and don’t function properly. Get a new glow plug from PartsAvatar at the best prices online.
3. Shift Solenoid – Blinking or flashing of the check engine light is a sign for damaged shift solenoid. Change it as soon as possible to avoid the P269B error.
4. Electronic Pressure Regulator – Emission of black smoke from the exhaust is a sign of damaged electronic pressure regulator. Alter it quickly.
5. Glow Plug Relay – Do you find the glow plug relay to be faulty? Replace it as quickly as possible to avoid malfunctioning of the system.
6. Engine Control Module – Conditions of misfire shows that your ECM is faulty. Fix it as soon as possible to avoid the P269B error in your vehicle by getting a new ECM from PartsAvatar.

Willing to know some common symptoms of OBD Code P269B? Your wish is our demand. Have a look at them below:

Common Symptoms

• The engine performance is diminished.
• Regeneration of the DPF will not occur.
• The service engine warning light or else the engine light will stay on.

We have listed out some ways which would help you to correct the occurrence of OBD Code P269B. They are mentioned here as follows

• Clear the error codes and test drive the vehicle to make sure the diagnosis is successful.
• This code type is accessible only to electronically controlled throttle bodies.
• Every function of the vehicle is virtually controlled by these controllers and the PCM remains as the primary controller.
• While turning the throttle actuator motor, it will, in turn, change the gear in the throttle body that is tangled with bigger gear.
• Replacement of entire throttle body must be done which comprises of the actuator motor and the throttle position sensor

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

• Firstly, the mechanic will use an
• OBD-II scanner or else a code reader as well as DVOM as it can help to perform the diagnosis successfully.
• As there is a huge number of circuits involved, it is best to leave it in the hands of the trained professionals.
• Some applications will use the inlet door to control the airflow through the intake tube by altering the degree to which the door can open according to the position of the throttle.
• Some of the common reasons for the low pump pressure can be a clogged hydraulic passage, a faulty pump, defective shift solenoid or a damaged electronic pressure regulator.
• If the engine mountings are broken, then you will hear crouching and banging noises.
• There is 2 important type of mounting- one is placed centrally which is very close to the bottom of the block and the other one is placed high on a block which is located on the inner wings or else the chassis members.
• The P269B error code specifically refers to the camshaft (cam) timing.
• The illumination of the check engine light will take place if the cam timing is over-retarded and the error code will be set in the vehicle.

Common Mistakes When Diagnosing the P269B Code

• Broken glow plug control module.
• Defective glow plug relay.
• PCM might be defective.
• Problem with the electrical wires
