you will need to remove the starter to gain acess to the ckp sensor. once you remove the starter look on the engine block and you will see the sensor. The only problem with doing this repair yourself is that you will not be able to preform the crankshaft position variation learn procedure with out a factory scan tool. The vehicle may crank an run, but the timing advance curves will be wrong so the vehicle will probably cut off every time you remove your foot from the gas pedal. Hope this info helps!
