i would think you would only have 1 lambda sensor

Hi some vectra's have two sensors in the exhaust but there is not two lambda. if yours is the one with two one will be on the exhaust manifold which is the lambda sensor and underneath the car just after the cat there is another one witch this one tells the ecu that the cat is working properly.

i dont suppose theres a how to on changing lambda sensor is there?,or if any one could post some quick tips..looks easy enough but there is restricted spanner space with the end of mine hitting the radiator and also there is not much space to get the spanner on,,,is it ok to remove the silver cover off the manifold..sorry these are basic questions for you guys but i am keen to learn

Hi i think they are a 22mm nut and they are both lambda sensors one in front and one behind the cat if the fault is lean or rich then i would go for a temp sensor first not a lambda
