Sourcing alternative Air flow sensor for Crv

[IBW]

Hi.

 

I have a 2016 1.6 I-Dtec SR CRV.  It has the engine warning light on which has been diagnosed with needing a new 'Air fuel ratio sensor 1'.  The error code are Error code: P0133 and P2A00

 

The local Honda dealer has quoted me over 700 pounds to supply and fit the replacement sensor..  the car drives fine and fuel consumption is normal.   So i'm looking to get a non-Honda replacement and a local specialist has recommended Denso as a alternative, but the problem is finding and sourcing the sensor needed.   The Honda part number is  Part number: H36531RZ0G01

 

Does anyone know where I can source a replacement sensor and what product number it would be please? 

 

Yours hopefully..
