HI there,

This is most commonly caused by the crank position sensor. This is mounted under the engine above the starter on the back of the engine. If by some chance the engine stopped running while the ignition key was on, this code can set. Sometimes just clearing it is enough to resolve the problem. If not, start with the crank sensor.
