>>28505562 (OP) Possible. Sensors in an engine do not like low voltages. If your battery is low and you're cranking you're going to be seeing something like 9 volts.
>>28505644 Based on the reading in the car it was actually around 11 volts but not sure how accurate this is. And as I said i was able to eventually start the car without any jump start, just had to wait a while. So I want to say the battery had no problem generally, just that it cant deliver enough power to the starter motor when its hot. So I'm not entirely sure what the connection is between failed cranks and the crankshaft position sensor This guy had the same exact problem as me with the same CEL though. >>https://www.camaro6.com/forums/showthread.php?t=577336
>>28505652 Oh, if you have a Camaro; that's probably the notorious grounding issue. The solution is: you add an extra ground strap to a certain area of the car. Apparently the connection between some of the chassis and the battery isn't super good and the extra ground strap bridges that gap I think it's like a $50 fix.
>>28506137 Yes I've seen that fix a lot. But what does grounding have to do with the heat soak issue itself? Isn't that just a bandaid to get more reliable current to the startup? >>28506583 Right now it's good. It was never the battery since I was able to get it to start. It was just too hot.
>>28507011 Grounds are important anon. I've seen a LOT of cars have a bunch of issues caused by a single bad ground. Bad grounds means high resistance. High resistance means heat generation and poor power supply. And the starter is the largest power draw the car sees. Add the ground fix and go from there. It's a pretty well documented issue
