ECU Showing 2 codes, help needed

[civicx3]

Ive got 2 codes showing up from the ECU, it seems to be 41 and 48 which from this list says its..

#41 - Primary oxygen sensor heater
#48 - LAF ( Lean air fuel sensor )

I cant find hardly any information on what these are, i thought it was the lambda sensor but that's code #1 or #2 so cant be that. Heated 02 sensor seems to be the first sensor in the exhaust going by this picture but wouldnt that be code #1 or #2 and not #41?!

Does anyone know for sure what these things are, have any pictures or know the best way to fix them or is it a case of replacing them?

Cars a M reg civic eg vei

Could be a bad connection on the oxygen sensor heater wires,

yeah could be, will check them all over this weekend

confuses me with codes #1 #2 and #41 looking like its the same thing

I think 1+2 are related to issues with the actual signal side of the sensor failing,

The codes you have would appear to be the O2 sensor not heating up correctly and most likely giving a false lean reading,

cars just failed its mot on emissions, just priced up a genuine honda o2 sensor and coming back with prices of over $400. Might as well just do a b16 conversion for that money

anyone got any experience with the cheaper aftermarket sensors? finding some on ebay for £15 - £45+ which is more my price range

this sensor is a 5 wire sensor and most im finding dont have 5 wires even though the ads say it will fit my model. The sensor i have here is a L1H1 sensor

thanks
