I replace my radiator. I have power. It's 2005 sentra. What could it be. Code p1121 from Hum
-
The Throttle Body is the most likely cause of the P1121 code, but since the code started after you replaced the radiator, you should try bleeding the coolant system first.
With the engine off and cool, remove the radiator cap. Run the engine with the radiator cap off. Hold the rpms up by pressing the gas pedal. Turn the heat on and keep the rpms up until the heat blows very hot. Make sure nobody is standing in front of the car. You will know when the air comes out because coolant will shoot out of the radiator opening. If the temp gauge gets high while doing it shut it down for a minute and then start again.
