P00D0 code meaning
Barometric Pressure - Turbocharger/Supercharger Boost Sensor B Correlation
Powertrain system Generic code P00xx codes Check engine light
What P00D0 means
With the engine stopped or without boost, the boost pressure sensor B (between compressor and throttle) must read practically ambient pressure. This code is set when it deviates from the barometric pressure sensor by more than a threshold; the code does not say which of the two is wrong. B denotes the second boost pressure sensor, for example on a second turbocharger. Manufacturers that publish their diagnostics run the same comparison under other codes. None of the published manufacturer documents searched uses this code; the explanation follows regulations and comparable manufacturer monitors.
P00D0 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 1 hours
- Clears after repairAfter a drive cycle
Symptoms of P00D0
- Check engine light on
- Reduced boost or limp mode possible
- Often no further symptoms
Common causes of P00D0
- Most likelyBoost pressure sensor dirty, oil-coated or drifting
- PossibleBarometric sensor drifting, also when inside the control module
- PossibleContact resistance at connector, ground or 5 V reference
- PossibleSensor port or hose leaking or blocked
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P00D0 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. |
| D0 | The exact fault in that area. |
What to do next
- Note P00D0 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 P00D0
What does P00D0 mean?
P00D0 means "Barometric Pressure - Turbocharger/Supercharger Boost Sensor B Correlation". With the engine stopped or without boost, the boost pressure sensor B (between compressor and throttle) must read practically ambient pressure. It is a generic code, so it means the same on every make.
Is it safe to drive with P00D0?
Drive gently and only to a workshop. With P00D0 the car can go into limp mode (reduced power) to protect itself.
Will P00D0 fail an emissions test?
Yes, it can. P00D0 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 P00D0 to fix?
Difficulty: easy. A typical repair takes 0.3 to 1 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P00D0 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
