P0046 OBD-II: Turbocharger/Supercharger Boost Control "A" Circuit
P0046 Severity
Moderate
Will P0046 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 P0046?
The engine computer (PCM) uses a Vane Control Solenoid (also referred to as a boost control solenoid) to control the amount of boost from the Turbocharger. If the Vane Control Solenoid does not operate as commanded, code P0046 will set.
