P02EA Diesel Intake Air Flow A Position Sensor Circuit Intermittent/Erratic
Position sensor signal jumps or drops out intermittently — connector or harness issue. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
Is it safe to drive with P02EA?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
