Hi,
I went through each code. Both are related but for somewhat different reasons. The one parallel I found is both indicate an open circuit between the sender and gauge. With that in mind, I suspect that is what we are looking for.
I attached the descriptions and diagnostics below related to the two different codes. Both require a scan tool that is bidirectional and can communicate with the vehicle. I'm not sure if that is something you have available to you.
Take a look through them and let me know if you are comfortable performing them or if you have questions.
Take care,
joe
