My sensors are not working. Any ideas on what the problem could be?

You need to keep the "Monback" transducer clean, or they won't work. Dust, dirt, mud, snow, ice...... any of them will cause it to quit working.

If it's clean and still doesn't work, the wiring is the next most likely culprit. If the wiring is sound, then it's probably the transducer itself.

what is a "Monback" transducer?

its the radar that senses if theres anything there when backing up, if it gets dirty at all it may allow it not to work.

i know they did have a recall on 04-07 but I've heard nothing about problems with a 08
the system will also disable itself if fault is detected in any of the sensors

I want to purchase an alarm sensor to detect objects behind my vehicle to protect my child. There are a wide range of systems/prices etc. so I'm looking on input from someone who actually has or installs these.

Check your sensors to make sure that they are working!

Ask someone to put the shift on the backup for you. Make sure he or she steps on the brake tight. Stand behind the bumber and start touching each sensor. If you feel each of the sensor vibrates, that means that sensor is good. If you don't feel at all, you may have a faulty wiring on the power wiring somewhere. Ask someone to check the fuse or 12v to drive that circuit.

I have an 04 F250 with tthe same problem. Where is the Monback located at? Also is there a fuse for this? This sensor is very helpful for me backing up to a trailer and boat. Any info would be great.

No offence but why don't you look behind your vehical before you back up ?
We have stickers on ALL our vehicals, cars and truck which read " WALK AROUND THE VEHICAL BEFORE MOVING IT ". Your telling us you will rely on
a machine to tell you if your child is behind your car ? Don't you think you
should look ? Why would your child be in the driveway in the first place ? Don't you think you would notice or is this just a new toy you want in your car ? J.M.O.

where is the transducer located at so that I can check it out? what about a fuse, is there one?
