How do you test a Hall Effect Sensor ( pick up )
The Haynes Manual says its beyond the scope of a Home Mechanic.

I am sure somebody here has a few ideas ;)

The Hall Effect sensor fails. This is cheap and easy to replace, but if you want to test it, Chriszw wrote that you can do this using a multimeter set to provide an audio continuity signal. Connect a 9V battery to the power and ground pins, the red test lead to the sensor signal pin, and the black test lead to the 9V battery negative terminal. Then slide a fat blade of iron, such as a feeler gauge, between the sensor and a magnet. The multimeter should stop sounding a tone, and the display should overrange. Chris suggested carrying a spare in the trunk since the sensor costs about $30 and tends to go bad. It really is a two minute job to replace it - it is in the distributor underneath the rotor. (Note: if you have DIS, or distributorless ignition, you do not have a Hall Effect sensor! All current Chrysler products have DIS, which was first used in 1991 on the Spirit R/T and was phased in on new engines and models afterwards).

It may cost a bit more, but I would go with one from a chrysler/dodge dealer. From my personal experience, they last longer than the ones from other auto parts places, like NAPA.

Upon examining the engine today I found oil leaking from the head gasket.
Which would explain alot of the problems I am having.

code 21 - coolant being burn through the exhaust
bucking - pressure not being able to build in the engine


As far as the Hall Effect Sensor
I think its a moot point right now.
But thanx for the suggestions
