Obd 2 Diagnostics

[dablik]

I didn't know what a HO2S is so googled and got a very useful-looking page of check / fix info here:- https://www.autoblog.com/2016/03/30/p003...ccounter=1

 

Thanks Steve, had a quick scan and bookmarked for a proper perusal a little later, it does mention stuff i've come across and i would like to check the wiring when i have time, interestingly the car is commonly used for 10 mile round trip down the motorway but also was sat for 3 weeks while used the other car and on holiday, batteries a bit low so wonder if lack of use, cold weather and infrequent use had created the problem.. it can often be unused for awhile...
