Nissan cars are often known for their high performance and dependability, but they are not immune to malfunctions. The Nissan Code P1065 is an example of this and is associated with the PCM Backup Circuit. This malfunction involves the Powertrain Control Module (PCM) detecting an internal problem in its ECM Backup circuit during the CCM test. The code is triggered when the key is on or the engine is running. Knowing the causes and solutions of Nissan Code P1065 is essential in order to fix the issue and get the car running again.
Causes and Solutions of Nissan Code P1065
| Cause | Solution |
|---|---|
| PCM Backup circuit is open or shorted to ground | Clear the codes and retest for DTC P1065 |
| Same code resets after clearing | Substitute a known good PCM and retest |
| Code does not reset after substituting PCM | Original PCM has failed, replace it |
| Faulty wiring or components | Inspect and replace any corroded wires or faulty components |
PCM Backup Circuit
The Nissan Code P1065 is associated with the PCM Backup Circuit. This circuit provides a backup to the PCM in the event of a power failure. When the PCM detects an internal problem in its ECM Backup Circuit during the CCM test, the code is triggered. The code is triggered when the key is on or the engine is running.
Clear the Codes and Retest
One of the possible causes of Nissan Code P1065 is a PCM Backup Circuit that is open or shorted to ground. To fix this issue, the codes must be cleared and retested for DTC P1065. If the same code resets after the codes are cleared, it is likely that the problem is a faulty PCM and a known good PCM should be substituted and retested. If the code does not reset after substituting the PCM, it is likely that the original PCM has failed and must be replaced.
Inspect and Replace Components
Another possible cause of Nissan Code P1065 is faulty wiring or components. To fix this issue, any corroded wires or faulty components must be inspected and replaced. It is important to remember that the key must be on or the engine must be running in order for the code to be triggered.
Conclusion
The Nissan Code P1065 is associated with the PCM Backup Circuit and is triggered when the key is on or the engine is running. This issue can be caused by PCM Backup Circuit that is open or shorted to ground, a faulty PCM, or faulty wiring or components. To fix this issue, the codes must be cleared and retested for DTC P1065. If the same code resets after the codes are cleared, a known good PCM should be substituted and retested. If the code does not reset after substituting the PCM, the original PCM must be replaced. Additionally, any corroded wires or faulty components must be inspected and replaced. Solving the Nissan Code P1065 issue is important in order to get the car running again and maintain its high performance and dependability. Nissan Code P1065 must be solved in order to keep the car running smoothly.
