Code P0043 2003 RAM 4.7L
Ok,
Need some help troubleshooting the P0043 code. Check engine light is on and code reader returns P0043. From from the code list means "H02S Heater ctrl Circuit Low Bank1 Sensor 3". The printout from Autozone where I had the code read says to check circuit fuse, relay defective or check wiring. Can anyone suggest maybe where to start with fixing this. Is this O2 sensor, or other. Thanks in advance.
