P1217 2002 NISSAN ALTIMA SEDAN Meaning
The Engine Control Module (ECM) controls the cooling fan based on vehicle speed, engine coolant temperature, refrigerant pressure, and air conditioner operation signal. The control system has a 3-step operation [HIGH/LOW/OFF].
If the cooling fan or another cooling system component malfunctions, the engine coolant temperature increases. When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is indicated.
