I have a 2009 accord v6. The code 3497 is showing. I have changed the oil pressure switch , the Vtec solenoid and just had the oil pump spring changed by a mechanic. The code returned after all this work was completed. I had taken the car to the local dealer to ask about a software update , but they said they were unaware of any updates for this car . Any ideas ??

 

P3497 Possible Causes

• Low oil pressure
• Restricted oil passage
• Engine mechanical condition
• Faulty Cylinder Deactivation Solenoid
• Cylinder Deactivation Solenoid harness is open or shorted
• Cylinder Deactivation Solenoid circuit poor electrical connection
