Parking Assist Sensor

EDIT: I wanted to share a quick fix I found for my faulty Parking Assist Sensor. I had been searching for a solution for a while, and I stumbled upon two YouTube videos that suggested using WD40 to fix the issue. The sensor would come on and then not go off. In both videos, they recommended spraying WD40 into the gap between the sensor and the part that holds it onto the bumper. To my surprise, it worked! The sensor has been functioning perfectly ever since. I’m guessing that maybe some water had gotten in between the sensor and the part, causing the sonar to malfunction. By using WD40, which displaces water, I was able to resolve the problem. I hope this helps someone else who’s been struggling with the same issue. It was quite frustrating to find a solution, but I’m glad I did!


I posted a question here earlier about a bad sensor in my bumper and got very little help. I have found some videos on YouTube for replacing it but no part was listed that was used. The dealer wants $289.00, Amazon is asking $213.00, both for OEM parts. I did find some after market parts for $13 to $17 on Amazon. That's a pretty huge difference! Taking a chance for the cheap ones definitly wont hurt if they don't work but I hate to throw away a couple of hundred dollars if I don't have to.

 

Based on past posts about these sensors, cheap aftermarket units will likely give you trouble.

Generally, when it comes to any Tundra sensors, OEM is the ticket. One exception is TPMS, where some aftermarket units can work ok.

Try the cheapies if you want but don't be surprised if you end of needing to replace them. Or, just hit the button and turn the system off if you don't need parking assist.

Looking at your signature, you have a lots of pricey mods and would appear to spend some coin on and take care of your truck. Considering this, I would put OEM sensors in and not worry about it for another 8-10 years.

 

I would avoid buying “OEM” or “factory” from Bezos-mart there’s a high likelihood of getting counterfeit.

Many online dealers will have better/discounted pricing and free shipping compared to the parts counters at local dealers.

As for aftermarket ones - I’ve heard mixed results. The sonar system is a bit finicky, and when I installed it in my truck and one other one, the only ones I could get to work correctly were factory originals.

 

Has anyone used:

I have a price for OEM that $120 cheaper than dealer.

I'm a BAM consumer personally, but I see those links are usually filtered out on here, unsure of why. If not BAM, then Sparks Parts.

I tend to agree with electronics on these trucks, use OEM when possible.

 

They are at $201.00
