Yep overkill and then some !
Most likely only one of the sensors are bad. That being said, if they are the same P/N, and this being a common issue, you'd think they would both eventually fail on every car, but seems like it's only one of them most usually.my test will be to replace it i took out #2 to replace it last week and installed the old one into the #3 slot will monitor it now but it seems temps are not so wide between #2 and 3 now
