That was my wife writing. I believe that my engine overheat condition is caused by my fan. I have replaced my fan motor, thermostat, water pump, and radiator. My engine overheats when I am sitting in traffic.
In no traffic, on the highway, the temperature gauge reads alittle higher than I want, but the needle stays out of the red zone.
What I need to know is if there is a temperature sending unit or something to cycle the fan motor or what?
Also, I have a code 23 or 123. I have a "Service Engine Soon" light. And a code beeper thing beeped out 1.2.3. I THINK that is the throttle position sensor and my rpm is going crazy. The idle is too high.
I tried the throttle position sensor from my Ford Explorer V6, but this made no difference.
How do I test my throttle position sensor to see if it is any good?
