P2073Manifold Absolute Pressure/Mass Air Flow - Throttle Position Correlation at Idle
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
- What you may notice
- Check engine light
- Unsteady or raised idle
- Often no noticeable driving fault
- Likely causes
- 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)
- RareDeposits at the throttle plate distorting the idle air path
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €0 – €350
