Yes.

There is no fuel pressure sensor.
its not really called a vtec sensor. its a Vtec Solenoid, the solenoid has an oil pressure switch mounted on the solenoid. When the head reaches a certain pressure the oil pressure switch sends a signal to the ecu and the ecu sends a signal to the solenoid to open the extra valves
On a 1998 Ford Windstar : The Mass Air Flow sensor is between the top section of the engine air filter housing and the engine air intake tube
The crank position sensor on a 2001 Ford Windstar van is located on the bottom of the engine. It constantly monitors the engine's crankshaft and reports information to the computer.
TCC is not a sensor. It is a function controlled by the PCM using a solenoid. There is no such thing as a TCC sensor. There is no such thing as a tcc solenoid.There are two solenoids, an on/off solenoid and a shift solenoid, that is located inside the transmission on the valve body assembly. It is necessary to access the valve body inside the transmission to replace the solenoids.
On a 2002 Ford Windstar , 3.8 liter V6 engine : The Mass Air Flow sensor is between the cone shaped engine air filter and the engine air intake tube . It is INSIDE a round shaped plastic housing

On top of the cam sensor synchronizer which is sticking out of the top of the timing cover on the front of the engine.
I'm not a mechanic / technician but I believe the EGR solenoid is mounted on the driver's side of the engine to the right and slightly below the PFE/DPFE sensor on the 4.0 L OHV engine ( The differential pressure feedback EGR sensor is mounted on the driver's side of the engine on the side of the upper "plastic" intake manifold on the 4.0 L OHV engine ) Helpfull
fuel tank pressure sensor or fuel tank level sensor? fuel tank level sensor is attached to the fuel sending unit, fuel tank pressure sensor is on top of the fuel tank.

No, a defective oil pressure sensor will not harm the engine as long as the oil pressure is what it should be. However, how do you know what the pressure is if the sensor is bad. Replace the sensor so that you can receive a warning if the oil pressure drops below what is optimum.
