STAR diag. will tell you better. This machine at the parts store don't know everything about every car just general info.
Better to spend the 98 bucks so you won't waste any more money.

You need to see why your O2 sensors are not getting heat. It could be a connector or wiring harness. This thread will help you debug it. If you don't have a DVM, it's time for a pro.
