P02EDDiesel Intake Air Flow A Control System - Low Air Flow Detected
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- 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. P02ED means the measured air mass stays below target with the control at its limit – too much EGR, a throttle stuck closed or a clogged intake – for 10 s (6.7) or 5 s (3.0). Typical causes are an EGR valve stuck open, a clogged air filter, a sooted throttle or a dirty mass airflow sensor. The engine lacks air: loss of power, smoke and high soot load. Other manufacturers using this code were not found.
