P0247 code meaning
Turbocharger/Supercharger Wastegate Actuator B
Powertrain system Generic code P02xx codes Check engine light
What P0247 means
The wastegate lets exhaust bypass the turbine to limit boost; actuator B is either a pulse-width-modulated solenoid on a pneumatic wastegate can or an electric actuator with a position sensor. B is the second turbo or actuator, so B codes only exist on engines with two. P0247 is the general circuit fault of actuator B, the counterpart of P0243. On GM's 3.0 litre twin-turbo V6 (LGW) it means an open circuit of more than 200 kΩ with the driver off, 10 of 20 samples, warning light in the first trip. Ford uses it on twin-turbo V6 engines with electric wastegates as the collective code for open and short circuits (0.4 s), together with P2ABE. Boost control on that side is switched off, costing power.
P0247 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0247
- Check engine light on
- Clearly less power, boost only at base level
- Uneven boost between the turbos
- Reduced engine power message possible
Common causes of P0247
- Most likelyConnector at wastegate valve or actuator B loose or corroded
- PossibleCoil or motor winding of actuator B open
- PossibleBroken control or supply wire
- Less likelyDriver stage in the engine module faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0247 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 2 | Area: fuel and air metering (injector circuit). |
| 47 | The exact fault in that area. |
What to do next
- Note P0247 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0247
What does P0247 mean?
P0247 means "Turbocharger/Supercharger Wastegate Actuator B". The wastegate lets exhaust bypass the turbine to limit boost; actuator B is either a pulse-width-modulated solenoid on a pneumatic wastegate can or an electric actuator with a position sensor. It is a generic code, so it means the same on every make.
Is it safe to drive with P0247?
Drive gently and only to a workshop. With P0247 the car can go into limp mode (reduced power) to protect itself.
Will P0247 fail an emissions test?
Yes, it can. P0247 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0247 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P0247 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
