- Faulty MAF or 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 MERCURY?
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.
Cost of diagnosing the P006A MERCURY code
The cost of diagnosing the P006A MERCURY 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.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P006A MERCURY Description
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.
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.
