how do you replace it...not easily...
if anyone finds replacing a windscreen wiper that hard they have to pay dealer labour prices i wouldn't bother buying an automobile,
To change a lambda sensor you need access to the cat (catalytic converter) , whch is near enough always situated underneath the floorpan (on a 206 its somewhere below the gearstick on the outside of the car).
a lambda sensor plugs into tha cat so really to change this you would problably need to raise the car in the air high enough to take the cat off, so you would problably need to take the car to a garage with a lift (you don't need to take it to the dealers unless you've got money to burn)
and if you don't have a clue like how to change a wiper blade next time your wasting money having someone on about £50ph do it stand there and watch how they do it so next time you can do it yourself and not have to pay for something that takes all of 2 minutes max
Year, engine?? Normaly lambda sensor is below exhaust collector
you plug them into the sensors on the exhaust downpipe!
All Down stream Lambda sensors are located(screwed into) the exhaust pipe, after the catalytic converter( usually with in a footafter the cat.).
On the 1.1, it's screwed into the exhaust pipe near the engine, and has a plug/socket connection on top of the tyransmission. The Haynes manual shows it and tells you how to change it. Cost approx �63.00 from Motormania you must also buy a lambda 22mm 3/8 socket to get it of,you can not clean them either
probably
Green and red wire on lambdA sensor
1st is in the exhaust manifold, just in front of the engine block. 2nd is behind catalyser screwed in the exhaust pipe. You shoud see in looks like a sparkplug with whires :)
they should both be on your exaust
Lambda is o2 sensor in exhaust pipe.
Are you sure you mean the co2 sensor? There is an o2 sensor on the exhaust in front of the catalyser, on later cars there are two sensors, the other being behind the cat. These are also called Lambda sensors. Hope this helps.
Answerif you are referring to lambda emissions sensors then these are usually in the exhaust pipe, usually in the catalyst, if you are referring to oxygen volume sensors then these are often in the inlet manifold, but this is dependant on the vehicle.supply some more into and id be glad to help.Adamski(adam.francis@snowsgroup.co.uk)its the heated oxygen sensor bank2 sensor1
air flow is usually connected betwen the air box and engine, lambda sonsors are on the cat or exhaust, both can appear as an O2 fault on most diagnostic readers
