P006A Ford Code - MAP - Mass Or Volume Air Flow Correlation
Quick Answer
Mass Airflow Sensor (MAF) measures the airflow rate into the engine and provides an analog signal to the Powertrain Control Module (PCM) which is used as a primary input for turbocharger and exhaust pressure control to calculate air flow for the EGR monitor. Common causes include Faulty MAF or MAP sensor, MAF or MAP sensor harness is open or shorted, MAF or MAP sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P006A Ford Description
Current PCM implementation contains a mass airflow interface, which consists of a two pole, differential input, low pass filter. This filter is designed to pass an analog signal, originating from the mass air sensor, while rejecting unwanted ignition noise, high frequency electrical interference, and ground offsets.
The input to the interface is the analog voltage signal difference between MAF+ (mass airflow signal) and MAF- (mass airflow signal return). The MAF sensor outputs an analog voltage signal calibrated to 0.5 V at the lower limit of the flow range and 4.75 V at the upper limit of the flow range. The Intake Air Temperature Sensor (IAT) is also Integrated into the MAF Sensor. The PCM uses the IAT signal to control timing and fuel rate during cold starts.
What are the Possible Causes of the DTC P006A Ford?
- Faulty MAF or MAP sensor
- MAF or MAP sensor harness is open or shorted
- MAF or MAP sensor circuit poor electrical connection
