Lambda Sensors Introduction
The DENSO difference
Designed with precision. Manufactured to the strictest OEM
Standards. Subjected to rigourous safety and peformance tests.
These are the exceptional standards behind DENSO’s Lambda
Sensors - an outstanding aftermarket programme of heated and
unheated configurations guaranteed to match each vehicle perfectly
every time.
Why choose DENSO? As one of the world’s foremost developers
and manufacturers of original vehicle parts and systems, DENSO
understands Lambda Sensor technology better than anyone else.
But that’s not just our opinion - leading vehicle manufacturers agree!
You’ll find DENSO Lambda Sensors fitted as original equipment in
Toyota, Mitsubishi, Honda, Jaguar, Volvo, Mazda, Suzuki, Subaru,
Isuzu, Daihatsu, Yamaha, Landrover, Daimler Chrysler, General
Motors, Opel/Vauxhall and many other vehicles. In fact since we
first produced them in 1977, several hundred million DENSO
Lambda Sensors have been doing their job measuring the oxygen
in vehicle emissions worldwide; making us one of the leading
Lambda Sensor manufacturers in the world.
That advanced engineering, OE quality and superior performance
is now available to aftermarket customers in our DENSO Lambda
Sensors programme. We use our unrivalled knowhow in each and
every Lambda Sensor we make.
Which is why, when you need a replacement Lambda Sensor,
there’s only one name to choose: DENSO.
Every DENSO Lambda Sensor is checked for 100% quality,
including high temperature signal output, air tightness,
continuity and heater resistance.
The technologies you need
Sensor types
As you’d expect, DENSO Lambda Sensors are available in a
broad range of applications. But they also offer all the advanced
technologies you’ll need to find exactly the right OEM quality
replacements for your customers:
> Zirconia Sensors Both Thimble and Planar types
> A/F Sensors Both Thimble and Planar types
> Titania Sensors
*For more details about the functionality and comparison of Zirconia
and A/F Sensors, see the Lambda Sensors Q&A section of this
catalogue.
Sensor housing
DENSO Lambda Sensors are available in two choices of OE quality
housing. And with DENSO Sensors, the housing is complete. There’s
no need for add-on parts such as flange adaptors!
> Screw type housing
> Flange type housing - including OE quality flange gasket
Sensor fitting
Whatever your installation need, DENSO’s two fitting options will
help you make the right connection every time:
> ‘Direct Fit’ Sensor - with OEM connector fitted, ready for
installation
> ‘Universal Fit’ Sensor - without a connector, enabling you to
re-use (and recycle!) the old part’s connector
Sensor inspection and replacement
> How often should Lambda Sensors be replaced?
DENSO recommends changing them as often as specified by
the vehicle manufacturer. But Lambda Sensors should also be
checked for functioning and efficiency at every vehicle check-up -
an engine that’s old or showing signs of excessive oil consumption
will need the Sensors changed at shorter intervals than specified.
> Why replace?
Lambda Sensor failure - whether through normal ageing, the
use of leaded fuels or contamination - can lead to damage of
the Catalytic Converter and cause expensive repairs. Failed
Lambda Sensors can also cause higher emissions, increased fuel
consumption and reduced engine performance including poor
acceleration, stalling and idling.
