Recently, I've been experiencing an issue with my back up sensors. Immediately after I put my truck in reverse, the sensors are going off. There is nothing at all behind me when this happens.

Also, when I tried using my remote start this morning, it would not work. Instead I got two beeps from my truck, almost like it was saying "F*ck you, I'm not starting". Went outside and started it with the key with no problem.

The only thing I can think of is that I washed the truck earlier in the day and maybe water or ice got somewhere it shouldn't? No ice on the back up sensors that I could see.

 

Mine did it also, but wiping the sensors and keeping ice and snow off cleared it up.

 

Did you happen to try the remote start again after you had used the key to start it? The reason I ask is a lot of factory remote starts will not operate if the alarm itself or warning chirp has been set off and it will honk multiple times to let you know that was the case. This is how it has worked on remote start vehicles I have had in the past anyway.
