1/12/2013 aggrunskythere is a temperature sensor on top of engine block on injector side of block. It has two pins on top of it. When your engine begins to run hotter than normal this sensor tells the fan to come on. This starts to happen frequently when the fan clutch goes bad. To check fan operation, crank engine, use a small screwdriver and short out the two pins against each other(you won't get shocked). Do not pull plug off of sensor pins while doing this check. Fan is defective if it does not turn on.

1/11/2013 JimmThe camshaft Hall-effect sensor is located at the front of the engine (standing at front of the car) to the right and close to the thermostat. A camshaft position sensor is not difficult to replace - check the 'How-To-Guides' feature on the AutoMD website.
Try the many on-line auto parts sources, such as; www.autopartswarehouse.com or www.rockauto.com for the replacement parts
