Q: What would make my camshaft positioning sensor keep messing up on my 2007 Ford F-150 fx4 with a 5.4 liter. I replaced it twice
What would cause my camshaft positioning sensor to keep going out. I’ve replaced it twice. I unhook the battery before I changed it. I looked in side the plug to make sure there wasn’t any broken prongs or dirt. But after that drive cycle my check engine light keeps coming on and it keeps saying my camshaft positioning sensor is intermittent And malfunctioning. Any and all answers or advice would be appreciated
My car has 1116840 miles.
My car has an automatic transmission.

The sensor itself can and should be tested prior to condemning it. In addition to a functioning sensor, the circuit back to the PCM must be intact and not have any loose connections, corrosion or high resistances. It is not likely that the sensor would fail multiple times and indeed the first sensor might have been perfectly good (unless it was tested directly; a code "implicating" the sensor or sensor circuit can never be the sole basis to replace the sensor; instead, sensor output must be viewed directly on a scope to diagnose the sensor/circuit) and the problem is simply in the circuit wiring/connections. To get this resolved, the recommended service to request is a check engine light diagnostic.
