JGC 2003 Code P1492 HELP!!!

2003 JEEP GRAND CHEROKEE
MY PROBLEM IS.... I HAD SOMETHING FIXED AT A GARAGE DEALING WITH THE COOLING FAN BECAUSE THE MODULAR HAD A MALFUNCTION THEY SAID. MY JEEP WAS OVERHEATING. A DAY LATER A GET A CHECK ENGINE LIGHT. AT AUTOZONE THEY SAID IT IS A P1492 ( APLSOL SOLENOID CIRCUIT MALFUNCTION) THEY DON'T HAVE A CLUE.
DOES ANYONE?:banghead:

Here is what I found for the P1492

Ambient/Battery Temperature Sensor Volts Too High - External temperature sensor input above acceptable voltage.

Sounds like maybe something was disconnected during the repair?

I would take it back and see what they say.

Take Care,

thanks!!! i'll try that and see what happens.
