P00F7 code meaning
Barometric Pressure - Turbocharger/Supercharger Inlet Pressure Correlation Bank 2
Powertrain system Generic code P00xx codes Check engine light
What P00F7 means
This is the bank 2 counterpart of the comparison between barometric pressure and the pressure ahead of the turbocharger or supercharger. At low air flow the inlet pressure sensor reads close to ambient pressure, minus the small loss across the air filter, so it must match the barometric reading. The code is set when the difference is too large; a clogged air filter or a leaking intake hose on bank 2 can cause it as well as a drifting sensor. None of the published manufacturer documents searched uses this code; the explanation follows regulations and comparable manufacturer monitors.
P00F7 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 P00F7
- Check engine light on
- Reduced power or boost limitation possible
- Whistling from an intake leak
Common causes of P00F7
- Most likelyInlet pressure sensor of bank 2 drifting or dirty
- PossibleAir filter or intake of bank 2 clogged
- PossibleIntake hose between air flow meter and turbocharger leaking or slipped off
- Less likelyBarometric sensor faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P00F7 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. |
| F7 | The exact fault in that area. |
What to do next
- Note P00F7 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 P00F7
What does P00F7 mean?
P00F7 means "Barometric Pressure - Turbocharger/Supercharger Inlet Pressure Correlation Bank 2". This is the bank 2 counterpart of the comparison between barometric pressure and the pressure ahead of the turbocharger or supercharger. It is a generic code, so it means the same on every make.
Is it safe to drive with P00F7?
Drive gently and only to a workshop. With P00F7 the car can go into limp mode (reduced power) to protect itself.
Will P00F7 fail an emissions test?
Yes, it can. P00F7 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 P00F7 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 P00F7 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.
