lambda fail 145 1.8tspark

mot fail on emissions test co and hc readings are well inside limits but lambda reading was 1.25, (fail level @ 1.030).
will replacing lambda sensor rectify the emission problem and is it just a case of fitting a new one or do i have to reset any of the electronics. I know my way around engines but not to hot on all the engine management mullarky so please be gentle.

The lamada test on an MOT doesn't test the lamada sensor but the oxygen level in the exhaulst gas, and is usually caused by a small leak in the exhauslt system after the lamada sensor.
