Mazda 3 P0012 Fault Code: Causes, Symptoms, and Solutions

Hi everyone, I recently replaced the crankshaft position sensor on my Mazda 3, but I'm still encountering fault code P0012. Additionally, the radiator fan is not turning on. I've checked the basics, but I can't figure out what's causing this issue. Any insights or troubleshooting steps for Mazda 3 with P0012 and non-functioning radiator fan? Thanks in advance.
