2010 Crankshaft Position Sensor May be Damaged if Timing Belt Breaks

Timing belts can break prematurely and cause serious engine damage. When replacing a broken timing belt, the crankshaft position sensor should also be replaced as it most likely has suffered damage as well.

    timing belt broke so replaced timing belt and tensioner belt and car still doesn't run. how do I know if timing is right to start with and how much does it cost to have timing set correctly and is there a way to check if its set right

    Engine has 58000 miles on timing belt replaced in 2010. Car made a thunk noise and CheckEngineLight came on, accelerator pedal wouldn't work. Came up with 0335 (Crankshaft Engine Sensor Position A)code as primary fault, and 0102 (MassAirFlow, low input) code as secondary. Kia suspects engine jumped timing but belt may still be on the pulleys and gear teeth.First real major problem other than AC compressor replacement last year.

    I just purchased this 2004 Kia Optima about 3months ago from Integreety Auto, well now the car cranks but WILL NOT start. I had it diagnosed which came up crank shaft position sensor, after buying the part myself because this shysty carlot wouldnt fix it, & taking it to auto shop, it still wont start. (Keeps doin the same thing). I dont want to deal with this headache, boy, this carlot got over on me.
