p0336 ckp sensor A 18/24 out of range

Question

i rebuild this engine a week ago and i run the car for a day after wich the engine light came on with this code
the car seams to run ok no misfiring however it turned off at the stop light for a second and than turned back on, maybe i was short on fuel, this morning on the way to school. we have a modis scaner here at school but beside reading the code I dont know how to read the rest. pls help
