When it comes to diagnosing a Honda Code P3497 can be a complex and difficult process for many mechanics. The code is defined as the Valve Pause System (VPS) Stuck Off (Bank 2), and is caused by a malfunction detected when the PCM sends ON (Open) or OFF (Close) command to the rocker arm oil control solenoid A (Bank 2). There are a variety of possible causes for this code, including poor connections or loose terminals at rocker arm oil control solenoid A (Bank 1), rocker arm oil control solenoid B (Bank 1), the rear rocker arm oil pressure switch, and the PCM, low or diluted engine oil, clogged oil passage of the rear bank cylinder pause system, “Short” circuit between the PCM and the rear rocker arm oil pressure switch, faulty rear rocker arm oil pressure switch, PCM may need to be updated with the latest software, and faulty PCM. To further diagnose the Honda Code P3497, the related service bulletin 13-055 must be consulted.
Causes and Solutions of Honda Code P3497
| Cause | Solution |
|---|---|
| Poor connections or loose terminals at the rocker arm oil control solenoid A (Bank 1), rocker arm oil control solenoid B (Bank 1), the rear rocker arm oil pressure switch, and the PCM | Check for loose connections and replace any faulty parts |
| Low or diluted engine oil | Replace engine oil and add fresh oil |
| Clogged oil passage of the rear bank cylinder pause system | Clean the oil passage to remove any clogs |
| “Short” circuit between the PCM and the rear rocker arm oil pressure switch | Check the wiring and replace any faulty wires |
| Faulty rear rocker arm oil pressure switch | Replace the rear rocker arm oil pressure switch |
| PCM may need to be updated with the latest software | Update the PCM with the latest software |
| Faulty PCM | Replace the PCM |
Poor Connections and Loose Terminals
The first possible cause of Honda Code P3497 is poor connections or loose terminals at the rocker arm oil control solenoid A (Bank 1), rocker arm oil control solenoid B (Bank 1), the rear rocker arm oil pressure switch, and the PCM. To fix this issue, a mechanic must inspect all connections and replace any faulty parts.
Low or Diluted Engine Oil
The second possible cause of Honda Code P3497 is low or diluted engine oil. This can be resolved by replacing the engine oil and adding fresh oil to the engine.
Clogged Oil Passage of the Rear Bank Cylinder Pause System
The third possible cause of Honda Code P3497 is a clogged oil passage of the rear bank cylinder pause system. If this is the case, the mechanic must clean the oil passage to remove any clogs.
“Short” Circuit between the PCM and the Rear Rocker Arm Oil Pressure Switch
The fourth possible cause of Honda Code P3497 is a “short” circuit between the PCM and the rear rocker arm oil pressure switch. The mechanic must check the wiring and replace any faulty wires to fix this.
Faulty Rear Rocker Arm Oil Pressure Switch
The fifth possible cause of Honda Code P3497 is a faulty rear rocker arm oil pressure switch. If this is the case, the mechanic must replace the rear rocker arm oil pressure switch.
PCM Update
The sixth possible cause of Honda Code P3497 is that the PCM may need to be updated with the latest software. The mechanic must update the PCM with the latest software to resolve this issue.
Faulty PCM
The last possible cause of Honda Code P3497 is a faulty PCM. If this is the case, the mechanic must replace the PCM.
Conclusion
In conclusion, Honda Code P3497 can be caused by a variety of issues, including poor connections or loose terminals, low or diluted engine oil, clogged oil passage of the rear bank cylinder pause system, “Short” circuit between the PCM and the rear rocker arm oil pressure switch, faulty rear rocker arm oil pressure switch, PCM needing to be updated with the latest software, and faulty PCM. To properly diagnose and repair the Honda Code P3497, the related service bulletin 13-055 must be consulted.
