P02ECDiesel Intake Air Flow A Control System - High Air Flow Detected
- 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
- Ford's 6.7 and 3.0 diesels control the air mass through the EGR valve and the intake throttle. P02EC means the measured air mass stays above target with the control at its limit – too little EGR, or the throttle cannot restrict enough – for 10 s (6.7) or 5 s (3.0). Typical causes are a stuck-closed EGR valve or clogged EGR cooler, a throttle stuck open or a mass airflow sensor reading too high. NOx rises; driving is usually unaffected. Other manufacturers using this code were not found.
- What you may notice
- Check engine light on
- Higher NOx
- Often no change in driving
- Likely causes

- RareBoost too high
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
