Guide To P067E OBD Error Code Solutions

<<See All OBD Codes

This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. Error code P067E can be defined as Cylinder 6 Glow Plug Control Circuit Low.

If the error code P067E is appearing, then it would mean that the powertrain control module (PCM) has detected a discrepancy in the glow plug control circuit for cylinder #6. You can always consult a source of reliable vehicle information to determine the location of the #6 cylinder for your year / make / model / powertrain configuration.

What causes this problem with the Cylinder 6 Glow Plug Control Circuit Low?

• Defaults in the glow plug connector
• Defective glow plug
• The glow plug control circuit might be opened or shorted
• Some flaws in the glow plug timer

P067E can be a simple code to diagnose when all diagnostic steps are followed in the proper order and all tests are performed.

A diagnostic scanner, a reliable source of vehicle information, and a digital volt/ohmmeter (DVOM) will be required in order to arrive at an accurate diagnosis of a code P067E. Use the vehicle information source to search for applicable technical service bulletins (TSB). If you locate a TSB that matches the vehicle make and model, symptoms exhibited, and the code stored, it will help you to arrive at a diagnosis

You may also need to obtain diagnostic flow charts, wiring diagrams, connector face views, connector pinout charts, component locations, and component testing procedures/specifications from the vehicle information source. All this information will be needed to correctly diagnose the stored code P067E

Now once you have performed a careful visual inspection of all glow plug and glow plug control wiring and connectors, connect the diagnostic scanner to the vehicle diagnostic port. Then retrieve all stored codes and freeze frame data and record it for later. After that test drive the vehicle to see if the code P067E is reset. Drive until one of two things happens: Either the PCM enters readiness mode or the code is reset. If the code is reset, continue with the diagnosis. If it is not, you are dealing with an intermittent condition which may have to worsen before an accurate diagnosis may be achieved

Here is a tip that the service manual will not give you. The best way to test glow plugs is to remove them and apply battery voltage. If the glow plug glows bright red, it is good. If the glow fails to heat up, and you want to take time to test it with your DVOM, you will likely discover that it does not meet manufacturer's specifications for resistance. Be careful not to burn yourself or start a fire when performing this test

If the glow plugs appear to be working properly, use the scanner to activate the glow plug timer and test for battery voltage and a ground at the glow plug connector. If no voltage is present, test the power supply for the glow plug timer or glow plug controller. Test all related fuses and relays as recommended by the manufacturer. As a rule, it best to test system fuses and fusible links with the circuit loaded. The fuse for a circuit which is not loaded may appear to be functional (when it is not) and lead you down the wrong diagnostic path

If all fuses and relays appear functional, use the DVOM to test output voltage at the glow plug timer or PCM (wherever it originates). If voltage is detected at the glow plug timer or PCM, suspect that you have an open or shorted circuit. You may seek out the cause of the discrepancy or simply replace the circuit

Common Mistakes When Diagnosing The P067E Code

• Glow plug control module might start failing
• Some faults in the glow plug
• Failure in the glow plug wiring harness
• People think that a P067E cannot be caused by a defective glow plug because this is a control circuit code. Don't be deceived; a bad glow plug may cause a variation in the control circuit that result in just such a code
• Huge mistake of attempting to diagnose the wrong cylinder is made by a lot of people. Save yourself a big headache and make sure that you are addressing the correct cylinder before beginning your diagnosis
