I've had 3 different dealerships try to diagnose my sensor problem and they so far have been unable to replicate it. I've had this problem since I purchased my car new 9 months ago. The really strange thing is that it goes away for weeks and then suddenly comes back continuously for a few days. This makes me think that it's a software problem and not hardware because bad hardware would make the sensors error all of the time.

I don't have the time or energy to take it back to the dealership again. I've just learned to live with it by turning off the sensors when they go crazy. Often, after turning them off for ~10 minutes and back on, it goes away for awhile.

Which button? Can u explain the process further please? I thin Otho u guys are speaking of foci equipped with front parking sensors? I have only the rear sensors and they work fine

My car has the parking assist feature so it includes both front and rear sensors. There is a button below the climate controls on the right that can turn off all the sensors. I use it to shut off the beeping when it is in error. I don't know if cars equipped with only the rear sensors have this button.

I have found that heavy rain and snow cause mine to beep when I'm stopped or driving slow. Kind of makes sense. I just turn it off during those times. Not sure that's what is causing your problems but it was driving me crazy until I realized it was the rain.

I've heard of these causes too but I get the error beeps in clear weather with no objects near the sensors.

Hi dragonpalm.

I'm more than happy to pass your info along to your CSM for another call, if you'd like. Just let me know if you're interested.

Hey guys see my past posts. Very easy to fix the problem, replace the sensors and be done with it. They are not very expensive.

I have definitely had mine false alarm sometimes, but not the same problem as dragonpalm.
Mine will go off sometimes while stopped at a light next to a large truck. There must be some resonant frequency in the engine or exhaust system of certain trucks and buses. This alarm stops as soon as the truck moves.
I have also had mine false alarm when a sensor got wet or dirty. A little drop of water covering the gap around the center of the sensor is all it takes sometimes. This usually happens after leaving a carwash, and will go away very quickly when I start to drive.
My falses are also usually not the fast beeping or continuous beep, I usually get the slow beep as if I am farther away from something.

I suggested they replace my sensors at the 3rd dealership I took my car to. There are 6 front sensors and 3 rear sensors. They told me that according to Ford policy, warranty work is only done when a problem is verified. Thus, they needed to figure out which of the 8 sensors were bad, if any. They then tested each sensor and updated the APIM and BCM for good measure. They found nothing wrong with the sensor system. However, it still acts up every now and then for me and is inconsistent. This is just my honest experience with this system. I think my case is rare but hopefully, anyone else experiencing this can glean some information from my experiences. Unfortunately, the fastest resolution to this is to buy and replace each sensor myself, or get a dealership to do the work with my money.
