2011 CRV parking sensors problem

[Markacc]

Hi, The front nearside parking sensor on my 2011 CRV went wrong - dashboard displayed Check System and indicated which sensor was faulty.  I replaced the sensor - the problem changed but did not go away.  Now I do not get any faulty sensor indications - but as soon as I drop below 5mph - even if nothing within 100 metres of the car - the dashboard indicates that there is an obstacle close by - in other words the sensor reacts.  Is there a way of rebooting the system, or maybe the sensor control module is faulty?  I have seen these for sale but cannot find where they are located on the car - no mention in any manual I can find.  Any suggestions would be appreciated

I wonder if the sensor resistance is different from the others....worth taking a reading from the new one and an existing one to compare.

I read an article from someone who said he had spent a lot of time on parking sensors and had never seen a duff one yet or one that could not be repaired by

driving the water out of it with wd-40 and sealed after with varnish.
