Need to know which engine you have i.e. 4 cyl or V6 to give an exact estimate as the sensor is located on different areas of the engine.
the 4 cylinder has the Crank Sensor on the right rear of the block below the starter motor. the V6 has it lower left of the block. The V6 Sensor costs about $100 and the 4 cyl is about $50. The labor is .6 hours for both engines, so this is a pretty good idea of what to expect in terms of cost.
