Parking Sensor Troubleshooting

The Problem

parking-sensor-error“Check Parking Sensor System” was the big orange error on my 2012 Honda Pilot's display. The day that the error showed up was the day our parking sensors stopped working. The button on the dashboard didn't work at all, no light, nothing.

We've had the car for about 5 years and we've become very accustomed to those sensors when parking anywhere, especially in our garage. The car was out of warranty so I was cringing at the thought of taking it to the dealer for diagnosis. I knew that would be expensive.

I did a Google search for the error message and I found that I wasn't the only person with this problem. Many people posted about this issue, and it appeared to occur on other Honda models, not just Pilots.

The Solution

My issue turned out to be a burned out indicator bulb in the switch. Yup, that's it. I couldn't believe Honda would be so stupid in their design that the entire system would shut down because of an indicator light!

On the other hand, I'm very thankful that it turned out to be something so easy to diagnose and fix! A $7 DIY fix in an hour is much better than a $150 dealer fix after he has my car for a day.

The Honda part number of my bulb was 35474-SZA-A11. I found it on eBay for $6.98 including shipping.

    I was experiencing the same issues as this video and was so happy to find it online. Everything was exactly as stated – THANK YOU! I bought the Bulb B (14V 80MA) part number 35474-SZA-A11 for my 2013 Honda Pilot Touring model from for $4.50 plus another $3.92 for taxes and shipping. The parts arrived the same week I ordered them. It took me 8 mins to carefully extract it from the dash and another 7 mins to pull it apart, replace the bulb and put it back together.

    Thanks so much for this info! Saved us money and frustration. Just wish I’d found it before taking my pilot to the dealer where I was charged $75 for them to hook it up to the diagnostics to tell me they couldn’t tell why the alert came on.

    I’ll add that your video helped me, too. The part for the 2014 Odyssey Touring Elite was 35856-TK8-A02; I got it from the dealership for about $7. The assembly is a little different, and even easier to access & swap the LED bulb than in the video.

      Great to hear, Brian! Thanks for the info.

      Hi Brian, I have the same car as yours. 2014 Odyssey Touring Elite. I wasn’t be able to reach any sides to remove the parking sensor from the dashboard. Do you have any guideline and what tools did you use for this process? I greatly appreciate your help.

  5. Tony Metze says:

    Thanks a million. It was not easy but I did it and now as good as new. Ordered two new bulbs and will replace both when they arrive. You saved me some serious money.

  6. Bob says:

    I will add my thanks
    Same car same problem
    What is the blue bulb for anyway?
    Any harm in just doing the switch and leaving the bad bulb in the lower position

    • Chris Heider says:

      It provides the backlight for the button when the headlights are on. Sure, you can leave the dead one there or probably just leave it empty. Haven’t tried that.

    All hail you! Thank you!!!!

    Hi Chris, Woud you show me how to mount the parking sensor on the Honda Odyssey 2011 Touring. The fact was that I drove one day on the Interstate. Suddendly, I ran over a piece of tire fell off from the semi truck. That struck my parking sensor on the passenger side. I ordered a new one : the sensor and the assembly. I opened the left side but I did not know how to open it. If you can .Give me some instructions. Thanks.

    • Chris Heider says:

      Unfortunately, I’ve never done that so I can’t explain it. Hopefully you can find another video on YouTube from someone who has. Good luck!

  9. Bob Long says:

    That part number wont pull up? Can you check to see if its right?

    • Chris Heider says:

      There may be none for sale on eBay at the moment. Just Google “35474-SZA-A11” and you’ll find tons of places to buy that bulb.

    Simply priceless. The frustration with the “all sensors out” indicator was completely undone with the ease of the repair. Works on 2014 Odyssey as well. They just made the access to the tiny bulbs easier…probably because this was an issue!

    Your video has probably helped 500 or 1000 people.

    I love the idea for handy dad videos. This one on changing light in parking sensor button was exactly what I needed for my Honda can. My wife is also thankful there was no light before she drove the van and it was on the next time I drove it.

  12. Memmy T says:

    This video was awesome. Saved me a lot of time and money. Thanks a lot.

  13. Lida says:

    Thank you so much for this helpful video. This help me fix my problem and save me a lot of money. Thank you again

  14. abdelghani says:

    Thank you verry much that was verry helpful for me. I’m from morocco and i was facing the same problem. My car is a 2012 Honda accord. You saved my time and money 🙂

  15. Erin says:

    Thank you!!! My ’14 Odyssey just went off warranty and every trip to the dealer somehow requires at least 5 hours with 3 kids in tow. Even for an oil change. I watched your video a couple times. And then, once I had the courage, I completed this fix in about 3 seconds. I am not joking. I owe you at least $200, plus my sanity (priceless). If any of your viewers want the photos from the 14 Odyssey, I can find a way to share. The replacement part # for mine seems to be 35856-TK8-A02, though I can’t find it on ebay, so I might just try a generic 14v 80MA type bulb. (The one I pulled out of my switch looks identical to the one in your video.) Thanks again.

    • Chris Heider says:

      Hi Erin. Thanks for the comment. You made my day. So glad I could help.

    • Henry says:

      Hi Erin,
      I’m glad you have this resolved. I have the same ’14 Odyssey but it’s Elite. Do you have the same buttons layout? I would appreciate to see your photos on how to remove the button module from the dashboard. I tried to open from the driver side dash and no luck from reaching to the back of the button with my finger.
