Interesting. I can’t think of anything else to say. My ford doesn’t have sensors. I just back up the old fashioned way. Back until I hear the sound of metal bending, then pull forward a couple feet.
Tried this technique on a 2016 Tahoe with the "service park assist system" message and found one sensor not functioning (dead). Just used a voice recorder on a smart phone to do my listening. Works like a charm. Genius idea! Kudos to the maker of this video! Thank you.
Do a search for Tahoe rear bumper removal. Not that big of a job... you might be able to get it out just by removing some of the fasteners holding the bumper and flexing the bumper to make enough room to get your hand up there to disconnect and remove. It may depend on the placement of the sensor you're changing.
Thankful to find this video is lu of paying $1000 for a new sensor i replaced my 2015 sensor and listened to the rest there all good now but still have the error will it rest itself or does it need reset anyone?
@@NekwaWatch In my case on my 2016 the problem actually ended up being a wire to one of the sensors in the wiring harness attached to the inside of the bumper. I found this by moving good sensors to the location of the non operating sensor. All this to say once the wiring was repaired, and the ignition was cycled off and on again the message did not reappear, and the system now works as it should.
Hi Hilltown, thanks for the info, just replaced all 4 (only 2 bad). Picked up all 4 from Amazon for $26.00. I have a 2007 Avalanche LTZ. Easy job!! Thanks again, Jimmie Rod.
Just tried this on my 2007 Chevy Suburban and it worked excellently. Save yourself the $100 diagnostic fee and the $100-$300 your dealership will charge to fix it and do this it literally takes 2 minutes. Buying a replacement sensor from O'Reilly's Auto parts for $40. Done
My sensor was constantly going off everytime I drive. Going from Park to Drive the sensor would come on that I was right up against something and yet there would be nothing in front of me for 10 - 15 yards. After watching your video, and seeing where the sensors were, I did not have a clue, I found the problem. There was a small bug stuck to one of the front sensors. I wiped it off. No more sensor alert. Thanks for posting your video.
I just tried it and it worked. I used my iPhone in the voice recording app and listened back to it. Sensor 1 was bad. U need to put it up as close to the sensor as possible and not touch the sensor. Thanks again. Next step amazon
I just purchased a 2015 Chevy Captiva sport with the check engine light on for VVT solenoids (both bad). After replacing them a couple of times (got bad ones), i finally fixed the check engine light. Next i saw this Service Park Assist problem and i had no idea what it was until i googled it. I was going to take it to the dealer and was dreading having to shell out big bucks to the Stealership. Thanks to your video, i should be able to fix this problem now especially as it seems one of the sensors is not sitting perfectly flush and the bumper was hit on that side slightly as the clips are out from the body! Thanks for saving me the money!
Surely I thought this was some kind of witchcraft so I got out my phone and I went to the back of my 2006 Chevy up lander and I did a video and sure enough on play back you can hear it clear as a bell. My drivers side corner was badd. Thanks man this was an awesome video
Helpful video. Never used it in my truck for the last 2 years I’ve had it but now that I’m selling it want everything perfect. Guy I bought it off had a spare in the glove box I never threw out. Straightforward video takes no time at all thanks for the help!
Nice troubleshooting steps. I checked all my sensors on My 2011 Chevy Traverse, they were all good. I figured the problem would be in the wiring Harness and sure enough the connector was not connected. Maybe I'll post a video of how I got to the connector and how to remove the Bumper cover to help others out there. Thanks again for sharing.
I tried this method on my 2008 Silverado and I couldn’t hear it! I think because when it isn’t working it shuts the whole system down on the early body styles like mine. Going to pick a sensor up online and trial and error it. Great video! Thanks for the idea!
Thanks for sharing this video, Absolutely awesome trick. In less then 5min I was able to find the problem with my #3 sensor. My Samsung phone on voice record worked perfect. A local shop had me thinking it was a wiring problem and would take 3-4 hours to fix. The dealership wanted stupid amount of money to fix. For less then $60 from Amazon and a total of 10min work. Truck is fixed. Do you have any tricks like this to fix the factory trailer brake system error on a 2012 Silverado Thanks again
Hi Hilltown, I just brought a 2011 silverado Z71 4x4 truck. The park assist service wasn't on the dash. I had a trailer hitch ball in my shed and put it on the hitch. well, the park assist service came-on the second day i was driving-it. I watch a youtuber stated that his hitch ball had interfere with the backup sensors, so he took the ball off and the message went-off. I did the same, took-off the ball, and no park assist message. go figure. I don't have to buy any sensor's.. good day..
2010 Tahoe for me Okay...I was able to use my emergency brake and put car in reverse and have a couple wheels blocked. (Wanted to be safe. I didn’t want to be run over or be pinned against the wall...lolol) I tried to listen with my naked ear and couldn’t hear anything from all 4 sensors. I then thought about using my voice recording app on my smartphone and could pick up the ‘feedback’ on two of the four sensors. Both on one side of the vehicle. I’m debating on buying two sensors or just have my dealer diagnose and verify it’s just the sensors and not a wiring problem on one side of the vehicle. Thoughts? And while I’m typing this, I just thought about swapping out one of the good sensors with a ‘bad’ one and see if that works... Thanks for the video. I had no idea where the sensors were and you gave me the idea to fix myself. I DID want to pass along the iPhone trick with the voice recorder app.
I would go with the cheapest option. Take one of the functioning ones and swap it with one that isn’t working to troubleshoot. I like that smartphone tip! Necessity is the mother of invention!
Great video. I found the one you have on Amazon for $12 but it didn't fit my 2018 Chevy Volt, that had a sensor dented by a golf ball sized hailstone! Got a $30 one from another source online. It fits electrically, but is slightly different. Anyone know how to reset the system? I still get a Service Park Assist message. Haven't driven far yet.
Realize 6yr old video. Question my dash has the message and no alert when approaching an object. If one sensor is bad does the whole system not activate. TIA
@@miguelbTGOD I did I just used my scanner and reset it. It happens to me truck because I have an aftermarket radio and every so often the trucks human interface does a scan and doesn’t see the factory radio. The park assist goes thru the human interface so it turns it off. You can get a scanner and just turn it back on
@@pablosbuickgarage i might have to get a better OBD2 Scanner. My blue driver one didn't show anycodes. Showed 0 codes. Appreciate the feedback though👌, il try taking the negative battery cable off the car for abit and see if it starts working again
I have the same fault with the same 2011 avalanche and it turned out to be the same right side unit that failed! Christ, the colour of our trucks are even the same! I’m more handsome though.😎
Bought my sensors from oreilys for 35$ each. I ended up needing 3 new sensors and the harness ( which was 100$ at the dealer) all the plugs back there corrode really easy.
@@HilltownCT its been ridiculous all the corrosion I have been finding in plugs and what not. Luckily its not my truck its a project I have been doing for someone els. I have a 03 suburban that I like way better than this 07 seirra lol
I have those rear parking assists coming up periodically and it drives me crazy. How do I do the microphone thing to figure out which one has the issue?
I don't recall what brand it was and I no longer have it. I could hear it just by putting my ear to the sensor, but it wasn't discernible on video. Someone recently mentioned in the comments that they recorded the sound with their iPhone voice recorder and played it back. You might be able to do that too. Good luck!

katrosper Anytime!
Can you hear the clicking or is that just from the microphone picking it up?
You can hear it if you put ear to it.
These are Ultrasonic sensors. They produce sounds over human hearing limits. You need a speciality tool to be able to hear it.
It's $50 for 4
$48.95 at local O'Reilly's
Yeah, ok....and if you dont have a mic??
Good idea to buy on line. 4 for $31.00 on amazon. $165.00 his price??? He must have phd.
Huh?
Amazon Prime......$15........just sayin.......
$25 for 4 sensors.
Can I just use the mic on the phone
Yeah, someone else on here said they recorded it with their phone.
Get another auto guy. He’s a thief!!
