I have the above vehicle. It is the HF model and I love the 44 mpg. The economy has died off and I need to replace the oxygen sensor. Mine has the factory five-wire with two pigtails that attach to the wiring harness. My parts house guy and I have looked extensively and can only come up with one that looks like the right one made by Wells. It carries about a $260
price tag. Anyone else run into this issue and resolved it in a less expensive way?
