Just bought an 08 Chevy Impala LS 3.5L two days ago. It was in a no start condition and a bunch of codes for low voltage, open circuit and also the P0641 code you have. Owner said he replaced the power steering pump, then after watching this video started to suspect the same issue on this car. Sure as hell once I removed the power steering pump the wiring harness going to my camshaft positioning sensor was eaten through and the sensor was broken too. Thanks for this video it saved my quite the fortune.

Well thanks for the video sir I will give that a try. It very well might be the problem I am having with my impala
Did it work?

Hopefully this works for you
Fixed ...one of my.crankshaft wires were pulled apart giving me the reduce engine. Symbol and reference 1. Circuit fault .I'm all good now
Me pasaba lo mismo cambie cuerpo de aceleración y demas cosas pero el problema seguia ahí hasta que hice eso también
Pretty sure this is my issue as well
Hopefully this video helps
@Whats_A_UA-cam it definitely did. I redid the wire in that area and the problem is gone. Thanks for the video.
i just cleaned them up and covered the exposed wires with electrical tape
How did you fix the wires if you don’t mind me asking?
Stripped the wire added a new one because they're so short or tape it up so it dnt rubb on the engine
