There are two possibilities...

  1. The crankshaft and camshaft sensors are not properly synchronized to each other. This is a procedure that must be performed with special tools.
  2. A bad alternator diode can cause this code to set due to voltage ripple. Have the alternator/charging system tested.

Sensors do not need to be recalibrated , the ecm should have the codes cleared . Then turn the ignition system on with data reader hooked up to see if sensors repaired the fault code.

position sensors have little to do with rough running engine
items like bad injectors, problem ignition control module, fuel pressure , HT leads valves, vacuum leaks all contribute to rough running
best run the fault codes first to determine what area to look at and fix the reported faults

Do a Web search under the terms (Your make, model, year vehicle) intake manifold runner. Or intake runner control solenoids, rods, etc. You may find Youtube videos.

The runners are sandwiched under or inside the intake manifold. Some had plastic clips which crumbled and the operating rods became disconnected. Some runners stuck too bad for the rods to move them.

You may have a bad wire or it could be in your wiper switch on your steering column. Have you tested to see if you are getting power at the motor?
