The answer is probably obvious, but I have to ask just to clarify...Yeah.. my CRV Touring has the kick sensor and it does come in handy at times. I believe Honda sells a kit to add it to EX-Ls which also have a powerlift gate but no kick sensor stock from the factory.
The only rub is one day I was sweeping in my garage and I reached to sweep some leaves from under my CRV and sure enough... it triggered the kick sensor. Luckily.. the garage door was open.. so no conflict between doors. I guess I could have come to the forum and started a complaint thread about it.. but instead.. I just laughed and took it all in stride.
I assume that you had the key fob on your person when you accidentally triggered the lift gate kick sensor?
