What P00FC means
The turbocharger outlet pressure sensor A measures the pressure directly after the compressor, usually ahead of the charge air cooler; FCA fits it as a combined temperature and pressure sensor. Boost control and compressor protection use the value. P00FC covers short dropouts or jumps in the signal that are each too brief for the low or high code, or changes faster than real pressure can move. Comparable intermittent monitors count range violations per drive cycle – Ford's MAP check, for example, sets after 25 events. The FCA case for the sibling code P00F9 was a sensor not fully seated with an unlatched connector, exactly the kind of fault that produces erratic signals; heat and vibration near the turbocharger add to it. GM and Ford do not use this code family in their published summaries – they rely on the boost sensor ahead of the throttle (P0235–P0238) – so no manufacturer document naming exactly this code was found.
P00FC at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 1.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P00FC
- Check engine light on, possibly only after several drives
- Occasional hesitation or brief loss of power under load
- Fault comes and goes
Common causes of P00FC
- Most likelyConnector loose, not latched, or terminals corroded or spread
- PossibleHarness chafed or broken near the turbocharger (heat, vibration)
- PossibleSensor with internal dropouts
- Less likelyEngine control 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 P00FC 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. |
| FC | The exact fault in that area. |
What to do next
- Note P00FC 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 P00FC
What does P00FC mean?
P00FC means "Turbocharger Outlet Pressure Sensor A Intermittent/Erratic". The turbocharger outlet pressure sensor A measures the pressure directly after the compressor, usually ahead of the charge air cooler; FCA fits it as a combined temperature and pressure sensor. It is a generic code, so it means the same on every make.
Is it safe to drive with P00FC?
Drive gently and only to a workshop. With P00FC the car can go into limp mode (reduced power) to protect itself.
Will P00FC fail an emissions test?
Yes, it can. P00FC 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 P00FC to fix?
Difficulty: easy. A typical repair takes 0.3 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P00FC 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.
