Ford Excursion :: Backup Sensors - Fast Ticking From Only One Sensor
Oct 30, 2010
Ok, so it seems I have 3 bad backup sensors on the 2002 Ex. Background information for those considering a repair:
I put the Ex in reverse, key in run and can hear "fast ticking" from only one sensor. Sensor removal is easy (at lease on the two outside sensors). Two tabs on the black housing in the bumper hold the cylindrical sensor in place. Release the two tabs and work the sensor out. I haven't tried to remove the bad inside sensor yet as there is a lot less room to work there.
Once removed, a single tab on the wiring harness connector holds the sensor in place.
Here is the problem I have. I can't get the sensor to LOCK back into the connector. I have backed the connector against the bumper and pushed on the sensor with all my strength and I cannot get it to lock back into the single tab on the connector.
Is there a trick I am missing? I am ready to try vice grips but I fear I will damage the connector.

Is it possible to turn off the backup sensors on my X ?
When I am towing these things drive me nuts!

Just started doing this. Sometimes I can get them to turn on in I hit the button enough. Switch going bad?

I can't find any info about this "always on" reverse light issue. My searches show that most people with the problem only have it when they put it in to revers. Mine's broken but the light is on all of the time indicating it's not working.
I can go through the sensors, but I think the system only recognizes sensor failures when the car is in reverse. What's my first/next step?

My Excursion had a mangled rear bumper when I bought it recently. I just bought a salvage one to replace it. I had it installed today. I want to salvage the backup sensors in the old bumper along with the license plate lights. How do these come out? They seem locked in there to me.

I'd really like to add these to The Beast, but don't want to drill through chrome. My bumper has some plastic running along the top (see pic). Just looking for info for the same bumper mounted the sensors there with success.

I'm having an issue with my backup sensors when its cold (40 and below). The issue is, they don't work. When I put it in reverse the sensor light on the dash comes on signifying they're off. I push the button to try to turn them back on and it stays on with no change. Once the outside temp heats up they start operating as normal. How to fix this?

I have a 2002 f350 that I have changed relays, control unit, checked fuses with no change. The hazards work normally. I'm ready to drive it off a cliff. I was told that it could be a bad ground. But no one can tell me where the ground may be. I have looked at the wire run from back to front with no problems found.

I bought the truck in 2005 but now that my kids are driving it I need to add a rear camera or sensors.

I have the backup sensor system, and occasionally turn it off with the dash switch when backing up a boat trailer. Never had to manually turn it back ON, because it is supposed to default to the ON position during startup.
Twice this week, after starting the vehicle, the OFF light stayed on the next day, and the system did not default to the ON position. (nearly backed the truck through the garage wall cause the damned thing didnt beep when it was supposed to!)
Works fine today, so problem seems intermittent...

Last night I backed my truck up to allow another family member to leave, and the back-up sensor alarm started beeping, like it does when the tail-gate is down and backing up.
The truck had not been driven on Christmas day, but it had rained and snowed lightly (dusting), then the temp dropped to 20 degrees.
Can a light dusting/ice cause the sensor to react the same as a close object. I think it does, just trying to confirm.

My back up alarm hasn't been working all the time. I checked for the clicking sound when it wasn't working & could hear the clicking. The light is on all the time when its acting up. Is there a control box somewhere?

The backup alarm sounds when I put the truck in reverse when there is nothing behind me. I found posts about people not getting any sound at all but none like mine. I'm guessing I have at least bad sensor that 'thinks' there's something in the way when there isn't.

My backup assist only works when it is raining!! I have read all the posts I could find on the back up system, but have not found one one my issue. I had my wife turn the key on, engine off and put the truck in reverse. I put my ear to each sensor and they are clicking. So I am assuming they are working right. I took the speaker out and cleaned it and put it back in. No beeping at all!!
It was raining really bad one day last week and as I was sitting at the curb in reverse waiting to back into the driveway a car passed me and the system started going off. It startled me and the kids. I backed in and it worked as it should. Later that night we went out to eat and it was still raining and the system worked as I backed into a spot near a light post.
The rain stopped and the truck dried out and now the back up assist is nonoperational again! What is going on? To me it seems the moisture is completing a circuit that is not being completed when dry!

So Wife did this nice "How-To" for the site and then we celebrated with a trip to Steak N' Shake. Halfway there I could feel it running a little off so I pulled up the app on the phone and connected it. I pulled up the codes and this is what I got.
So am I looking at an O2 sensor you think? It's shifting early and chugging a little as well. When driving it sounds a little like I have dual exhaust or a flowmaster. When sitting still at a light there is a small bump like bass turned WAY low coming from the exhaust as well. I turned around halfway there and went home and we took the wife's Highlander

Recently smogged my excursion, passed the emissions but failed self test. O2 sensors not ready. Drive it 40 miles everyday and still wont pass.

Currently I have a license plate camera wired always on connected to a 7inch lilliput monitor infront of my center console on that hump in the floor. The monitor is connected to a 12v plug on the dash. In this configuration, I have to reach down and turn the monitor on whenever I want to reverse and im hoping I can make it turn on whenever I go into reverse. Right now, if I turn it on then turn the truck off, the monitor stays on with a bright blue no signal screen which forces me to turn the monitor on, then off, every time I reverse if I want to use it.
Any way to make the monitor turn on/off when I put my Ex in reverse?

About a month and a half ago my Elantra while accelerating starting to make a fast ticking noise that was noticeable from usual with the radio and Air off but not terribly loud. The car still seemed to run the same.
So I took the car into the Dealer for my usual oil change and the recall for the automatic transmission and had them check it out. I was expecting nothing major. Turns out the service manager said a control armed failed as well as a piston and the damage was done. The will have to replace the entire top half of the engine at least and check the lower parts while taking it a part. They let me drive off and said to bring it back on Tuesday. Said he will drive to the rental car place and set me up in a rental while they fix it. Estimated to take 4-5 days while further checking into it.
It was noted as a "knock" in the upper part of the engine on the form I was handed after the car was checked out. They also said they would not bother doing an oil change on the car because of this issue. The car has a little over 27K miles on it.

I have a 2001 VW Jetta 1.8T manual transmission... I just purchased it...upon starting it up, it runs fine... After I have run it for a while, it gets a distinctive, constant, pretty fast ticking sound near the engine...
It's hard to pinpoint where it is coming from, but it seems to be coming from the right side of the engine or from an EGR valve?
It only makes the ticking sound AFTER it has fully warmed up and i have driven it awhile...and only at idle...if i rev up the engine, it goes away instantly...but starts again when it idles...

Outside backup sensors both went out on my03' Excursion, but the inside ones are still working.

My reverse camera goes over the mirror, its a mirror when not in use and a camera when in reverse. The way this one is set up, the camera taps switched 12 volts at the rear of the car (tapped trailer connector for these) and the video signal runs forward (ran under headliner to center console to mirror). The monitor needs 12 volts, ground, and + 12 volts when I shift into reverse. I just read a half dozen threads where people suggested tapping into a black wire with pink stripe in the driver's kick panel. Just checked, no such wire on mine. I do not want to run a wire back from the taillight, this seems backwards since the power goes from the front of the truck to the reverse light in the taillight I just need to find the right wire. I checked the reverse relay and the fuse in the fusebox and they are both 12 volts when the truck is on, so they must be prior to the reverse switch.
