Guide To P069A OBD Error Code Solutions

<<See All OBD Codes

Why are glow plugs used? What is a P069A error codes? They are used in diesel engine to preheat the cylinder. If the ECM finds that the glow plus is not operating, the P069A error code is set.

Glow plugs help in providing the required heat during cold temperature to the engines. Hey are heated during the initial start and before/after cranking. The Powertrain control module monitors coolant temperature and glow plug voltage by controlling the ON times. If the feedback voltage is not within the range, the error code is set.

What causes this problem with the Cylinder 9 Glow Plug Control Circuit Low?

• Poor glow plugs.
• Glow plug control circuit is shorted or open.
• Glow plug connector is faulty.
• Glow plug timer is damaged.

1. Glow Plug Relay - Check if the glow plug relay is properly connected. If not, fix them properly or replace them if damaged.
2. Glow Plug Timer - Are you in search of this component. Get them from Parts Avatar at an affordable cost.
3. Electrical Component - Every component of your engine system has to function normally. If not it can give rise to this error code. Check for faults and replace them as needed.
4. Glow Plug Circuit - if the glow plugs are not properly connected, the brightness will be less. Replace with the right replacement part from Parts Avatar.
5. PCM - A faulty or damaged PCM of your vehicle needs to be replaced immediately to avoid error.
6. Starter Relay - If your vehicle does not start, then it’s because of a damaged started relay. Replace the faulty part instantly.

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 P062D here:

Common Symptoms

• More black smoke from the exhaust.
• Drivability issues.
• Engine start up delay
• Less fuel efficiency.
• Storage of engine misfire codes

Here are some ways with the help of which you will be able to correct the OBD Code P069A:

• The real multiple-displacement is turned off which has 3 types of displacements and configurations. The diagnostic procedure is very big which shows the trouble codes in the in the air conditioning display. The customers misunderstood it, and the technology got quickly retired.

Here are some steps which you should follow in order to diagnose this P069A fault code:

• In order to properly diagnose you will need a scanner, trusted source of information and a DVOM. Search for an accurate TSB and locate it to match the symptoms, vehicles model and make and other stored codes to help solving the error code.
• You will need additional information like diagnostic flowcharts, wire diagrams, connector face views, connector pinout charts, component positions, and testing process to properly diagnose the error code.
• Visually inspect the glow plug, glow plug control wires, connectors and connect the scanner to the vehicle to recover codes and freeze frame data. Test drive the vehicle and either the PCM will enter readiness mode or it will be reset. Continue diagnosing if code is reset. If not, there will be an irregular condition and you have to worsen it for proper diagnosis.
• It is best to remove glow plugs and apply the voltage. If it glows red, it’s good. If not test it with a DVOM to meet the specification of the manufacturer. Be careful while performing this test.
• If the glow works properly, activate the glow plug timer and test the voltage with the help of scanner. If you don’t find voltage, test the glow plug timer/ controller for power supply. Test all its related fuses and relays as said by manufacturer with loaded circuit. The fuse which is not loaded with circuit will appear to function normally, but it will lead to wrong path.
• If both the fuse and relays function properly, test the output voltage with a DVOM. If you find the voltage, there can be open or short circuit which you can replace easily.
• As it is a control circuit code, the error can happen because of faulty glow plug. But a bad glow plug can only be a cause which results in error code.
• Ensure that you diagnose the right cylinder as it can save you from a big headache.

Common Mistakes When Diagnosing the P069A Code

• Faulty glow plug control module.
• Faulty glow plug.
• Faulty glow plug wire harness.
