94 taurus fan always runs
I have a 94 taurus with a 3.0, after changing the heater core piping. The fan runs all the time and the engine runs at a high idle. The check engine light is on. I've replaced the engine coolant temp sensor, the intake air temp sensor and throttle position sensor. All those items are the codes that I'm getting 113, 118 and 123. Any help would be greatly apprieciated.
