It would appear that a code 42 is for an impact sensor (located out by the front grill)
as this sensor is exposed to the weather it could be corrosion on the connector OR a bad sensor OR a totally FUBAR connector.

If you decide to tackle this yourself do this
Turn the key off
Place the key on top of the dash where you can see it
then start repairs.
the reason for turning off the key is to disable the airbag system.
The reason for putting it on top of the dash is when you get to the sensor and go to unplug it, you can look through the windshield and verify the key is off.
When you get to the sensor, unplug it and look at the pins on the sensor and connector. If they appear clean or maybe a bit whiteish plug and unplug the sensor several times. See if that makes a difference.
If on the other hand the pins are corroded, or the sensor looks like it might have water damage you will have to replace the sensor and possibly the pins in the connectors. A new sensor is no problem, but the pins in the connector are probably beyond your capabilities. If you unbolt the sensor for any reason, bolt it back up before turning the key on. Do not let it dangle.
Even after repairs you might have to have a shop clear the code (I’m not familiar with Ford’s system, on a Volvo even though the system was repaired the code and light would remain.)
