What P2073 means
The engine computer compares the measured air mass, or the manifold pressure, with what the throttle opening and engine speed predict. P2073 means the two disagree in the idle range. Ford's diesel OBD summary 2023 explains its approach: an airflow adaptation factor is learned in an idle cell and a load cell once per drive cycle; if the idle value ends up outside its band, P2073 is set. For the 6.7L Super Duty chassis that band is about +27 % and -13 %; the 3.0L diesel only checks the load cell. Ford bulletin 22-2115 reprograms the PCM of 2011 to 2012 F-Super Duty 6.7L trucks that set P2073 or P2074. Ford's 2014 code list also gives it MIL status. Air leaks, a dirty sensor or a clogged filter are typical; P2074 is the load case.
P2073 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2 hours
- Clears after repairAfter a drive cycle
Symptoms of P2073
- Check engine light
- Unsteady or raised idle
- Often no noticeable driving fault
Common causes of P2073
- Most likelyUnmetered air entering after the air flow sensor (loose clamp, cracked hose, leaking gasket)
- PossibleAir flow sensor element contaminated or drifted, adaptation runs out of range
- PossibleOutdated PCM calibration (Ford 6.7L 2011–2012, bulletin 22-2115)
- Less likelyDeposits at the throttle plate distorting the idle air path
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2073 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 0 | Area: fuel and air metering and auxiliary emission controls. |
| 73 | The exact fault in that area. |
What to do next
- Note P2073 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 P2073
What does P2073 mean?
P2073 means "Manifold Absolute Pressure/Mass Air Flow - Throttle Position Correlation at Idle". The engine computer compares the measured air mass, or the manifold pressure, with what the throttle opening and engine speed predict. It is a generic code, so it means the same on every make.
Is it safe to drive with P2073?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2073 fail an emissions test?
Yes, it can. P2073 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 P2073 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2073 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.
