Hi guys struggling to find a whole of information about what the fix is to the heater code, or troubleshooting procedure. Guess I was hoping for miracles with a online SM or something being available. Looking for someone who has experience in trouble shooting or am I just looking at a new pump assembly for sure. I am stock currently but over 100k miles considering going weight loss if this is as significant cost as I think it may be. Thank You for any help, also any good trustworthy shops in Indiana ?
