Thanks in advance for your assistance with this manner... The CEI is giving me a hard time throwing code P118. I changed the ETC sensor, Engine coolant level senser, a relay and the Thermostat. The Temperature gauge works when it wants to and the fuel gauge has a lot movement up and down. I then noticed noise from the drivers side cooling fan so I changed the whole unit (both fans). Thought I had it beat- I cleared code by disconnecting battery and such. The CEI came back on and I get the same code. any suggestions?
