Got anymore info. What was the engine doing when you got the code. Was it misfiring, running normal, accelerating, decelerating. If you disconnect the power train control module with the ignition key on you might erase the stored pulse value from the crankshaft position sensor (this would include leaving the key on til the battery is drained completely). This sensor sends pulses to the PCM when the reluctor wheel teeth rotate past the sensor. The PCM uses the crankshaft position sensor pulses in order to synchronize the ignition and the fuel injector operation, and in order to time the interval between each CKP pulse. Check for a chipped or damaged reluctor wheel, incorrect alignment of the CKP sensor to the reluctor wheel, excessive crankshaft run-out, interference in the signal circuit to the CKP sensor, or incorrect ratio of crankshaft to camshaft pulses
If there isn't anything wrong with the sensor or the reluctor adn everything looks okay, a scan tool can make the PCM relearn the values. I hope this will get you started in the right direction
