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


  • Firstly research the technical service bulletins specific to your vehicle make and model. Next step is to the engine oil and check if it is serviced up to the needed level.
  • Once this is done, then the next step is to look for all the related components and parts with the cylinder 6 exhaust valve control circuit.
  • Once located, check for any physical damage through an in depth visual inspection.
  • Check the wiring and connectors for any bare wires, burn spots, scraped etc. After all of this contact a technical to check for the configurations and see if every incorporated component within the cylinder 6 exhaust valve control circuit is in good shape.

Advanced Steps - These steps will be vehicle specific and will need few technical equipment to ensure the safety and accuracy.

You will need a digital multimeter and technical references. Here the oil pressure gauge will help you in your troubleshooting process. 


Voltage Checks - Also the required voltage will depend upon the specific vehicles and the circuit configurations.

In case you diagnose the lack of power source or ground, then you might require continuity tests to check the wiring integrity, connectors integrity and other components.

Also perform the continuity tests with the power removed. No continuity will be an indication of faulty wiring that is open, shorted or corroded and must be repaired or replaced.
