Hey guys I need some help with a code. I got the oxygen sensor code for bank 1 sensor 1. And heater circuit code. So we put in a new 02 sensor. Reset the memory. Drive the truck for a while. Code comes back. We hook up the diagnostic computer. We can turn the heater circuit on and off with the snap on tool. The trucks fuel tables and fuel consumption stays the same. We checked for a damaged wire. The voltage is all good. Is there anything else that can be causing this? Thanks!
