Hey all,

I had the very same issue, got a replacement hose from Cox motor parts and fitted it. Managed to reset the fault with a cheap bluetooth reader.

Roughly 3/4 days later the very same fault appeared? P2A01, which is an overheating o2 sensor (bank 1, sensor 2).

Looking at the temp range for that sensor, it's less than 0.5c out. Genuine issue or faulty sensor? Any advice welcome

Hi
Thanks so much for the pictures and knowledge
My 2015 diesil seems to have the same issues
I have replaced the hose which was damaged probely when changing the air filter and being brittle
The parts guy told me my hose was a newer version
I wonder why
Honda was the cheapest vendor?
The car appears to be a lot more pleasant to drive
I have sent for a code reader to clear the flashing lights hopefully
I will update after I try to reset the codes

[underwood278]

Ordered a code reader from Amazon for £30.00
Honda wanted £40.00 to stick a reader on it
Did not really know how to use it but reset the codes and its sorted

I have all this warnings on dashboard for months too..computer reads "Mass air flow sensor 'Air flow too low' " - ODB code P00BC .. checked intake and mechanic said its still good and recommend i change MAF sensor..so i did and ofc it didnt worked..afterwards he changed the map and o2 sensor and without luck..next thing he said i should go to Honda and do ecu software upgrade but im not sure is that even a thing ?

Lights came back on a week later
I had just cleaned the mass airflow sensor (does disconnecting the wires send a signal to ecu)
Code says P20A01 bank 1 sensor 2
O2 sensor issue
I have reset the code and will see if it comes back
MPG may be down slightly
But I dont want to dive in but will wait for the code to come back as pending or as a live code first

[underwood278]

Changed the O2 sensor
The code came back as pending
Will see what happens
but car drives better thru the town smoother gear change and less clutch judder

[underwood278]

Sorry I meant the code came back and then decided to change the sensor

[underwood278]

Changed O2 sensor all faults gone and passed mot
