Looks like new lambda sensor needed. Should be a straight-forward fix.

i had the same P1166/1167 error (checked with obd scanner)

i replaced the primary lambda sensor with denso part 234-9025
and reset the ecu, and now the car is running well.

i also checked the lambdas voltage with the obd scanner and now they react to engine load changes

Update on this,finally found the correct Lambda sensor[Denso 234-9025] in a breakers in Leeds,Pick-a Part UK. Honda wanted £208 but I paid £35 inc P&P.
Very happy now,no warning light on and car running great.

Result. Great price aswell, especially including p+p

sorry I forget to say that Denso 234-9025 is for F20B6 engine only.

F18 has different lambda sensor
