What are you testing, the heater which would be the 2 black wires? If so, the reading should be .8- 1.4 Ohms at 68 degrees F. The 13 Ohms is definitely not correct. They told you correctly when they told you not to use aftermarket sensors. They often don't work and your light comes back on. I would buy a Denso and be done with it. By the way, your caps lock is stuck on.

If you were talking about the heater resistance, and with the #'s, I assume you were, I can't say it won't make ANY difference, but I doubt it will make much. If you do a search on Google and read up on the function of the heater, especially in Florida, you'll see that it doesn't function much anyway in the summer. It shouldn't have done any damage. The new sensor may function better in what it's supposed to do, but the heater will have little effect on it.
