Check engine light Ford Freestar 2004 obd2 cod p0108 and p0406 pl can you explain the difination of p0108 and p0406?
P0108 Manifold Absolute Pressure/Barometric Pressure Circuit High Input:
The PCM read a high voltage (4.3 volts) from the MAP sensor for more than 7 seconds. This problem is usually electrical and can be solved by replacing the MAP sensor (in most cases).
P0406 Exhaust Gas Recirculation Sensor A Circuit High:
Your vehicle has an electronically controlled EGR valve that allows exhaust back into the engine to be re-burned (as a measure to lower emissions and increase economy). The PCM commands the EGR to open and close and monitors the action via a pintle position sensor. That sensor is no longer functioning. In most cases, this problem can also be fixed by replacing the EGR valve.
