invented the Lambda oxygen sensor in 1976. Bosch is now
the world's number one name for original equipment and aftermarket
requirements - with a total of more than 500 million Lambda
oxygen sensors produced to date.

Lambda sensors are subject to extreme
conditions and are now a critical part on any new vehicle.
A lambda sensor in perfect condition is a requirement for
a reliably functioning engine and thus for ensuring low
fuel consumption, low pollutant emissions and the correct
emission values. Bosch lambda sensors are unbeatable thanks
to their long service life, excellent operation and optimum
Only if the
lambda sensor is working perfectly will your engine will
be able to operate to its full performance capacity
and reach the emission limits!
What is a
Lambda Oxygen Sensor and what does it do?
lambda sensor (also known as an exhaust gas
oxygen sensor/probe) is an electronic device
that measures the proportion of un-burnt oxygen
(O2) in the exhaust gases.
It was invented
by Robert Bosch GmbH in 1976 and is the key
sensor in determining the air-to-fuel ratio
on modern engines.
Lambda sensors produce
a voltage signal that recognises the amount
of un-burnt oxygen in the exhaust gases. It
sends this signal to the engine management system
which uses this signal together with information
supplied from other sources to determine the
correct air-to-fuel ratio.
ratio is extremely important to a combustion
engine and directly effects the amount of engine
power, fuel consumption and exhaust emissions.
With the Lambda
sensor playing such an important role, it is
therefore essential that the sensor is working
perfectly all the time to maintain the correct
level of engine performance, fuel consumption
and exhaust emissions.
Advantages of fitting a brand new
Lambda Oxygen Sensor
Regular checking and replacement
of your lambda sensor is vital for:
consumption, engine output, driving properties
and lower emission levels.

fuel consumption in comparison to a significantly
aged or faulty lambda sensor.

Symptoms of a

common cause of premature failure
of lambda probes is contamination
of fuel with silicones (used in
some sealings and greases) or silicates
(used as corrosion inhibitors in
some antifreezes). In this case,

the probe tip with an oily black

causes build-up of black powdery

caused by failure of the probe itself,
or by a problem elsewhere in the
fuel rationing system.

applications may appear
be identical apart from
just an engine code,
power output or chassis
number. The fitment
codes are also used
when certain models
have more than 1 lambda
sensor fitted which
is very common on high
capacity engines where
up to 4 different lambda
sensors could be fitted.
So for example, F1 could
be an advert for the
lambda sensor used for
cylinders 1-3, and F2
could be the one used
to for cylinders 4-6.
the advert title has
an F number at the end
of it, then this simply
means there is more
than one advert listed
for that exact application.
If your model has an
F number in the title
then please check all
adverts before purchase
as there will be differences
in the fitting data
and there maybe different
part numbers available
for that exact model.
