Yes, it does fix the problem, I had the same thing and had to pay the full price. Do yourself a favor and get the heater core and condendsor replaced while they have it apart. The cost of the new sensor is $20. 00, $50. 00 for the heater core and $200. 00 for the condensor. 85% of this job is labor taking the dash out. I didn't want to pay $800. 00 for labor again on anything else that might fail soon. Parts were cheap. Good luck.
