In freezing temperatures with a chill factor of 13, your 2014 Impala LTZ is experiencing a no-crank issue accompanied by a P0641 code related to the 5-volt reference circuit. Start by checking the battery voltage and connections, ensuring they are clean and secure. Examine the wiring and connectors associated with the 5-volt reference circuit for damage or loose connections. Inspect relevant fuses and replace any blown ones. If you have a spare key, try using it, as issues with the security system might be a factor.

Hi there,

A P0641 code is a general diagnostic trouble code that occurs when the ECM/PCM detects a problem with the voltage output from the sensor reference voltage A circuit. The code is set when the ECM/PCM detects an open or short in the sensor reference voltage A circuit. Start checking system fuses and fusible links with the circuit under a full load and blown fuses should be replaced. Do a visual inspection of sensor system related wiring harnesses and connectors. Repair or replace damaged or burned wiring, connectors, and components as required. Click this link for more information about the trouble code from our CarParts resource blog. I hope this helps!
