What P00B0 means
Boost control B here is an electronic actuator with its own electronics (a "smart" actuator), usually on the variable turbine geometry, with its own position sensor and controlled over a data bus or a pulsed signal. It checks itself and reports internal faults to the engine control module; documented examples are pattern errors, overcurrent and checksum errors. The control module cannot narrow down a fault inside the actuator further. B denotes the second, separate actuator. P00B0 is set when actuator B reports an internal fault. No manufacturer description naming this exact code was found; the explanation follows its documented counterpart.
P00B0 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor1.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P00B0
- Check engine light on
- Loss of power or limp mode with reduced boost
Common causes of P00B0
- Most likelyElectronics or motor inside the actuator faulty
- PossibleSector gear or vane mechanism sticking (soot, coking), causing overcurrent
- PossibleWeak supply or ground, corroded connector
- Less likelySoftware of actuator or control module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P00B0 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 0 | Area: fuel and air metering and auxiliary emission controls. |
| B0 | The exact fault in that area. |
What to do next
- Note P00B0 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 P00B0
What does P00B0 mean?
P00B0 means "Turbocharger/Supercharger Boost Control B Module Performance". Boost control B here is an electronic actuator with its own electronics (a "smart" actuator), usually on the variable turbine geometry, with its own position sensor and controlled over a data bus or a pulsed signal. It is a generic code, so it means the same on every make.
Is it safe to drive with P00B0?
Drive gently and only to a workshop. With P00B0 the car can go into limp mode (reduced power) to protect itself.
Will P00B0 fail an emissions test?
Yes, it can. P00B0 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 P00B0 to fix?
Difficulty: hard. A typical repair takes 1.5 to 4 hours of work. This is a job for a workshop.
Will P00B0 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
