2009 22ve - Dealer readings, need help translating

[MexTex]

I had the engine trouble codes checked by the dealer and I wanted to see if someone could help me translate what the findings were.

SPN723 Count 1 Cam/RPM sensor voltage below normal or shorted, crank position sensor, data erratic intermittent or incorrect, data moderately over range

From what I'm reading, I need to change out the crank position sensor. But what else do I need to look at? They said I may also need a new ECM.

Start off with crank sensor. Most likely that is the culprit. Check the connector as well. Be sure it has no corrosion.

Do you know where the location of this sensor is on a 2009 Tige 24VE with the 343 PCM EX engine? 5.7L? Thanks in advance.

SUPER old post but yes, the crank position sensor is located at the 7 o'clock position in the BOTTOM of the timing chain cover behind the crankshaft balancer. It's held in place with a single 8mm head bolt and has a quick disconnect wire connection. Once the bolt is removed, it can be pulled straight out but may require some wiggling.
