Crankshaft position sensor on 2005 Chevrolet Impala

Where is the crankshaft position sensor located? I know it could be in 2 different places. I just want to know like where at on the engine block it could be because I just got my harmonic balancer replaced and now the sensor is bad and I don't want to have to take it off again if the sensor is not behind it.

Crankshaft position sensor A is behind the harmonic balancer. crank position sensor B is left rear of engine. Sensor A has three wires red, black, green, joining light green, yellow /black and blue/ black.

ok another question. I took my car to autozone and they told be it was bad but didnt tell me which one. My guess is the one behind the balancer because my balancer broke off due to my power sterring had a leak and i'm guessing also leaked onto that sensor. What do you think?

a3.4has a24xsensor is mainly fuel timing and#1 resset ignition alsoknownascam pos. then a cranksensor for 1/4/2/5/3/6pulse will causeano start or engine stall 24x sensor will most likely stay running but have extended cranking with a very sluggish accelaration
