I am getting a parking sensor problem. Does anyone know how to check which sensor is giving me fault? Is it through odb2 or the hardware diagnostic? Thanks

 

I have a2019 RDX and about the second year of ownership the right most front corner sensor would beep about 80-90% of the time. IT would shut off after accelerating to about 10 MPH but it was annoying every time I stopped. Brought it to the dealer and they confirmed that it was beeping when it should not be beeping. They were not aware of any diagnostic test that they could perform that would help in repairing it. They claimed to have called engineering dealer support line and no help there either. Their "solution" was to replace the entire front bumper panel that contained the sensors at an estimated cost of about $2,000. Not happening. I just turn it off with the button and if I need some help when parking I turn it on and then shut it off again. It's the only issue that I've had that Acura service could not fix

 

The sensors themselves are pretty cheap and I *believe* just plug and play. You can probably replace your faulty one for under $100.

If it's just the corner one, you may even be able to reach it from the fender well vs removing the whole bumper, but either approach is pretty straightforward - one just involves removing more bolts and clips than the other.

 

What exactly is the issue?

My post here might help you out and with finding a cheaper alternative to OEM sensor
