P006A — MAP - Mass or Volume Air Flow Correlation Bank 1
The expected relationship between manifold absolute pressure (MAP) and mass airflow (MAF) on bank 1 is violated. One of the two sensors is reading incorrectly.
General code reference. Confirm the definition and diagnostic procedure for your vehicle's year, model and engine. A stored code alone does not identify a failed part.
Affected components
- Map sensor
- Mass air flow sensor
- Intake system
Possible causes to check
These are possible checks, not a ranked diagnosis. Follow the vehicle manufacturer's test procedure before replacing parts.
- MAF sensor contaminated
- Intake/vacuum leak
- MAP sensor reading drifted
