P069D OBD Error Code: Problem & Solutions

<<See All OBD Codes

Do you have any knowledge on P069D error code? Just give a read. Before the engine starts, glow plug helps in preheating the cylinder. If the glow plugs for cylinder 10 is not functioning and has high circuit, then the powertrain control module will set the P069D code.

The heat which is necessary to start the combustion all through the cold temperature is set by glow plugs. During the early start of the engine, earlier and in the course of cranking, glow plugs are heated. The coolant temperature as well as voltage of glow plug is supervised by the engine control module. If the voltage of feedback is not within the bound amid the controllers to the ECM, this error code will be set.

What causes this problem with the Cylinder 10 Glow Plug Control Circuit High?

• Weak glow plugs.
• Shorted or opening in glow plug circuit.
• Flawed glow plug connector.
• Scratched glow plug timer.

1. Glow Plug Relay - Check for the proper connection of glow plug relay. If not, fix them properly
2. Glow Plug Timer - Looking for the right replacement part? Get them from Parts Avatar at an affordable cost.
3. Electrical Component - Every section of your engine system has to function habitually. If not it can give rise to this error code. Check for errors and replace them as needed.
4. Glow Plug Circuit - Look for proper connection of glow plug circuits. The brightness will be less if not connected properly. Replace with the right replacement part.
5. PCM - A damaged PCM of your vehicle is a common error and it needs to be replaced immediately to avoid P069D error code.
6. Starter Relay - If your vehicle delays during the start, then it’s because of an injured starter relay. Replace the faulty part as desired.

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P069D code by mentioning some major symptoms below:

Common Symptoms

• More black smoke from exhaust.
• Engine drive complications.
• Interrupted engine start up.
• Scarcer fuel efficiency.
• Engine misfire faults.

Have a look at some ways with which you can correct the P069D code:

The new multi-displacement system will turn off opposite pairs of cylinders, allowing the engine to have three diverse configurations and displacements. P069D code involves elaborate diagnostics procedure. Still, the system was troublesome, misinterpreted by customers, and the erratic failures led to the technology being quickly old.

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 Control Module Ground Strap, Power Steering System, Powertrain Control Module, Fuel Injection Control Module, Powers Steering Control Circuit and many more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this P069D fault code:

• If you have to properly diagnose you will need a scanner, main source of information and a DVOM. Hunt for an accurate TSB and trace it to match the symptoms, vehicles model and make and other stored codes to help cracking the error code.
• You will need supplementary information like diagnostic flowcharts, wire diagrams, connector face views, connector pinout charts, component positions, and testing practices to suitably diagnose the error code.
• Visually check the glow plug, glow plug control wires, and connectors and connect the scanner to the vehicle to recuperate codes and freeze frame data. Test drive the vehicle and you will witness that the PCM will enter readiness mode or it will be reset. Carry on with diagnosis if code is rest. If not, there will be an uneven condition and you have to make it worse for proper diagnosis.
• It is best to take away glow plugs and apply the voltage. If it glows red, it’s decent. If not test it with a DVOM to meet the arrangement of the manufacturer. Be careful while carrying out this test.
• If the glow works suitably, activate the glow plug timer and test the voltage with the support of scanner. If you don’t find voltage, test the glow plug timer/ controller for power supply. Test all its connected fuses and relays as said by manufacturer with full circuit. The fuse which is not full with circuit will appear to function usually, but it will lead to incorrect path.
• If both the fuse and relays perform well, test the output voltage with a DVOM. If you find the voltage, there can be exposed or short circuit which you can change easily.
• As it is a control circuit code, the error can occur because of damaged glow plug. But a corrupt glow plug can only be a cause which results in error code.
• Confirm that you diagnose the right cylinder as it can save you from a big headache.

Common Mistakes When Diagnosing the P069D Code

• Crashed Glow plug control module.
• Smashed Glow plug.
• Glow plug wiring harness flawed.
