Fan Mode
Temperature A/C Pressure
Primary (RH) Fan ON 109 C 229 F 189 psi
Primary (RH) Fan OFF 105 C 221 F 150 psi
Secondary (LH) Fan ON 112 C 234 F 240 psi
Secondary (LH) Fan OFF 108 C 227 F 210 psi
Additionally, the PCM will turn off the
fans at higher vehicle speeds (above 48 MPH I believe) since running fans can
actually impede airflow through the radiator at high speed. Each fan also has a
minimum running time. Once activated, the primary fan will run for a minimum of
50 seconds, and the secondary fan for a minimum of 26 seconds. Finally, certain
Diagnostic Trouble Codes (DTCs) may cause the PCM to turn on one or both fans.
