    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum.

I have a problem with a 2016 3.8L Sedan. The car drives fine for the first 5 to 10 minutes then the car stalls, check engine illuminates. When the car is restarted the tach doesn't work.

Here are the engine codes, any ideas would be great. Thanks in advance.

End of report.
 
You have listed too many error codes for anyone to assist in remotely diagnosing your vehicle's problem. It seems to me that you should find a competent repair shop.
 
I suspected these culprits—ECU, wiring, or crankshaft sensor. Took a wild swing and swapped the crankshaft sensor... jackpot. Car’s running like it owes me money.

Appreciate all the input... Lol

Thanks for your prompt response. Did you complete the crankshaft sensor R&R yourself or take it to a local shop?
