I have a code 1332 which indicates a possible camshaft possition sensor issue, the car runs very smothly at idle, although takes 3-4 cranks to start, is it possible that the sensor may only need to be cleaned?? it is a pretty pricey dealer part although I have seen them sell on Ebay for less than $50 in the past but have had no recent luck with current listings. thanks in advance for input.
