Need to have the codes read by a repair shop or if Autozone is still performing this, then tell us what code came up -

Autozone did test it and the code came up as p1660 which is the cooling fan control circuit fault.....it says the ECM has detected an improper voltage level on the output driver module for the cooling fan driver circuit. -
