Will a bad plug coil cause a crank shaft position sensor code to come up as well?

2002 ford f150

No. A coil that is bad will set misfire codes. A bad crankshaft sensor sets the code for the CRK sensor.
When the crankshaft sensor completely fails you can verify it because you will have no spark AND no injector pulse.

  • Would a faulty water pump, on a 04 Ford Freestar, cause the Fuel Rail Pressure Sensor to go bad? There's definite spray pattern on the underside of the hood from the water pump going. Could antifreeze have gotten into the fuel rail sensor and caused it to fault? Is it possible to clean the Fuel Rail Pressure sensor or any corrosion? Part is EXPENSIVE.

  • My Ford Transit headlights turn on in off position and turn off in the on position? I'm a new driver, just passed my test. My van has some issue with the lights: namely, the lights turn off in the on position when the dash lights come on, and turn on when they are supposed to be off. This means that I'm driving at night without dash lights as I need to have the lights switched off in order for my headlights to be on. Might this be an electrical issue? Would anybody be able to give me advice and possibly know how much this costs to repair?
  • How to take off my throttle position sensor? Screws stuck? I have a 1991 mercury cougar which is a part of the ford family. Forums say that the screws are glued in the factory. Is this true and I only have a screwdriver which I can't put leverage in because she it is in a tight Space. And I can't put torch in there
