P0665 OBD-II: Intake Manifold Tuning Valve Control Circuit High
P0665 Severity
Moderate
Will P0665 go away on its own?
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
What causes OBD-II fault code P0665?
The Intake Manifold Tuning Valve allows additional air to flow through the intake at higher RPMs. If the engine computer (PCM) detects that the Intake Manifold Tuning Valve is not operating as requested, code P0665 will be set.
