Been told by my friendly mechanic that after a diagnosis my Focus 1.6 Setec (52 Plate) that the above sensors need replacing. Has told me hat the Cma Shaft sensor is around £50, but doesnt yet know the cost of the Lamda Sensor.

How much do one of these cost??

 

you can get universal lambda sensors for about £30, or ones with proper connectors on will cost more. don't buy from ford though

 

Pretty sure if your cam shaft sensor goes down the car won't run......

Lambda sensors are consumbale items though
