P006A NISSAN Possible Causes
- Faulty Mass Air Flow (MAF) or Manifold Absolute Pressure (MAP) Sensor
- MAF or MAP sensor harness is open or shorted
- MAF or MAP sensor circuit poor electrical connection
How do I fix code P006A NISSAN?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Tech Notes
- Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compressed air or Mass Air Flow Sensor Cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replace the mass air flow sensor.
Cost of diagnosing the P006A NISSAN code
The cost of diagnosing the P006A NISSAN code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected
A difference exceeding the specified value develops between a value transmitted from the Manifold Absolute Pressure (MAP) Sensor to Engine Control Module (ECM) and an estimated intake pressure of intake manifold calculated by ECM, based on a Mass Air Flow (MAF) signal.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P006A NISSAN Description
The Mass Air Flow (MAF) sensor is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. The mass air flow sensor controls the temperature of the hot wire to a certain amount. The heat generated by the hot wire is reduced as the intake air flows around it. The greater air flow, the greater the heat loss.
Therefore, the electric current supplied to hot wire is changed to maintain the temperature of the hot wire as air flow increases. The Engine Control Module (ECM) detects the air flow by means of this current change.
