Diesel Intake Air Flow B Position Sensor Circuit Intermittent or Erratic
Same as P2396 with intermittent or erratic signal. 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.
Affected components
- Diesel intake air flow b position sensor
Common causes
- High likelihood: Intermittent contact at connector
- Low likelihood: Connector with intermittent contact under vibration
- Low likelihood: Harness routed against vibrating component
Diagnostic notes
- The malfunction indicator lamp may illuminate
- This code can affect emissions
