Hello, just purchased a 19 Silverado 4.3l I’ve been chasing my tail looking for a fix. I am showing the 2 following codes.
P0117 and P0119 (see screenshots). I am lost. I have replaced the coolant temp sensor, reset the codes. Drove and it came right back (the Service engine light).
i have cleaned the connection with contact spray, connector looks fine too.
checked battery cables they are tight.
Cooling fans are stuck on 90% of the time as well. Temp gauge bounces between cold and normal operating temp. It never exceeds the normal temp.
any suggestions would be welcome.
I also meant to add it starts really rough and or stutters.
Please and thank you
