Pontiac Repair: 1996 (2.4L) Pontiac Sunfire - Replace Camshaft & Crankshaft sensors?, camshaft sensor, crankshaft sensor

Question
My check engine light is on.  So, I went I went to AutoZone and had them run
the
diagnostic test.  It came back w/ three codes, the Oxygen Sensor, Cam
sensor (or
camshaft sensor), and the Crankshaft sensor.  The guy said I had to replace
all of them.  
I know how to replace the Oxygen sensor, but I don't know about the other
two.  Long
story short, I can't figure out how to replace the other two because I don't
know where
they're located.  Any help would be GREATLY appreciated as I can't find any
information
about this on the net.

Thanks in advance! (I hope!)

Hi Graziano:

Well first off I doubt it needs both of those sensors. but that is neither here nor there. I'll answer your question. the cam sensor is located on the cam shaft housing neat the intake manifold it faces the front of the car. It has a connctor on it with three wires. The crank sensor is locted in the engine block near the oil filer it has a connector on it with 2 wires. Both sensors are attached to the engine with just 1 bolt. when you replace then GENTLY pull and twist them at the same time to get them out of the engine. DO NOT pry on them they will break off and then your in big trouble.depending on which oxygen sensor code you have #1 sensor is in the exhaust manifold and #2 is in the exhaust pipe behind the converter. Good luck :)
