Some 2018-2019 Ford Flex, Explorer, Taurus and MKT vehicles equipped with a 3.5L EcoBoost engine may exhibit a MIL on, Service Advance Trac message, Hill Start Assist Not Available message, and/or a lack of power along with DTCs P0107, P0108 and/or P0109.

This may be due to a faulty MAPT (manifold absolute pressure and temperature sensor). To correct the condition, using a scan tool with the key ON/engine OFF, access the PCM and monitor the following parameter identification:

1. BARO (press)

2. MAP (press)

3. TCBP (press)

4. TURBO INLET (press)

If the MAP (press) PID value does not read within 10.35 kPa (1.5 psi) of the other sensors, replace the MAPT sensor.
