P0046 & P0047 Land Rover turbo actuator fault
Is your Land Rover operating in reduced-performance mode with fault codes P0046 and P0047 stored? This indicates the engine control unit has detected abnormal boost control circuit operation. For vehicles fitted with 2.2L Duratorq engines that utilise electronically controlled turbochargers, these symptoms are commonly caused by a turbo actuator malfunction.
Resolve P0046 & P0047 on your Land Rover
Both P0046 and P0047 Land Rover fault codes are frequently caused by an internal failure within the turbo actuator and not the turbocharger itself.
When the actuator no longer regulates boost pressure correctly, the engine control unit will detect abnormal operation and limit engine performance to mitigate damage. This is a common issue, and we can help to resolve it.
On the Freelander 2 and first-generation Range Rover Evoque, turbo actuator failure is a common issue on 2.2L Duratorq diesel engines.
Failure of these units will generate these fault codes:
- P0046 - Turbocharger/Supercharger Boost Control “A” Circuit Range/Performance
- P0047 - Turbocharger/Supercharger Boost Control Solenoid Circuit Low
This malfunction develops within the turbo actuator itself, and replacing the full turbocharger assembly will not resolve the root cause. Professional test and rebuild of the turbo actuator is required to clear P0046 and P0047 fault codes on the Land Rover. Send your unit for testing by completing this test form.
How Land Rover P0046 and P0047 codes are generated
The engine control unit continuously monitors the electrical operation of the turbo actuator control circuit. When an internal fault develops within the actuator, it result in increased current draw during normal boost control.
As the Land Rover’s ECU detects that the boost control circuit is no longer operating within the expected parameters, it stores the fault code P0046. As the fault progresses or becomes more consistent, the ECU may also store P0047, indicating a low or unstable control signal within the turbo actuator circuit.
For Land Rover Range Rover Evoque and Freelander 2 models, P0047 frequently appear alongside P0046 and indicates an internal actuator fault. Clearing the fault codes alone will not resolve the underlying issue as the root cause is an internal turbo actuator failure.
How to solve your Land Rover’s P0046 and P0047 codes
When your Land Rover has P0046 and P0047 stored, you will often be recommended to replace the turbocharger, but that is unnecessary. These faults are caused by an internal failure within the turbo actuator. Replacing the actuator does not address the root cause of failure and often lead to the same issue returning, as it contains the same components that are prone to failure. Instead, we have a much more effective solution.
Our P0046 and P0047 Land Rover turbo actuator rebuild service
We are specialists at diagnosing and resolving P0046 and P0047 Land Rover fault codes caused by a turbo actuator failure. Each actuator is tested on advanced rigs to ensure the fault is fully confirmed before any rebuild is carried out.
We remanufacture each actuator with higher-than-OEM specification components, restoring accurate boost control and permanently eliminating internal defects.
Our service offers a 2-3 working days turnaround and is a more affordable solution compared to a brand new turbo actuator. We include a lifetime warranty by providing a reliable and long-term solution you can trust.
Common failure symptoms:
- Restricted performance or limp mode
- Loss of engine power
- Poor acceleration under load
- Engine management light illuminated
- Persistent turbo boost control fault codes
Common fault codes:
- P0046 - Turbocharger/Supercharger Boost Control “A” Circuit Range/Performance
- P0047 - Turbocharger/Supercharger Boost Control Solenoid Circuit Low
Test and rebuild:
Each turbo actuator is tested on a hardware-in-the-loop (HIL) rig to simulate real operating conditions to accurately check performance, which allows us to detect if there are internal malfunctions.
The actuator is fully remanufactured by our skilled technicians to restore correct operation. All components used in this process are OEM-quality or higher, ensuring consistent performance and long-term reliability.
Programming:
Your turbo actuator retains its original manufacturer programming during the rebuild process. No additional programming is required once the unit is refitted.
Quality:
Each of our actuator rebuilds is fully verified before leaving our workshop, ensuring it meets our standards. This attention to detail is reflected in our rebuild defect rate of just 0.49%.
Warranty:
Lifetime unlimited mileage*
