Is there another Crankshaft position sensor other than the one in the Dizzy?

Last year I was getting a Check Engine Light, and error codes 4 and 9
4 CKP - crank position sensor
9 CYP - cylinder sensor
I replaced the entire Distributor last year, and the trouble codes went away for a while.

Now I am getting the CEL and the same error codes again.
Is there a Crank Position Sensor anywhere else on this car?

 

no its in the distributor, try looking at the connectors for corrosion and the wiring for any loose wires

 

Check the warranty on your distributor. If it failed shortly after the warranty expired I would avoid that brand of parts in the future.
