My garage has told me that the excess emissions on my Sonata V6 2.5L
Year 2000) are to high and the diagnostics are reporting a
malfunctioning lambda sensor. They are asking for £250 for the part
which *may* fix the emissions problem.

The car is probably worth only a few hundred pounds so can anybody
tell me if I can buy a universal, or alternative sensor to replace the
apparently defective item?
 
I don't know how readily these are available in the aftermarket. It has
been the case, however, that some generic sensors do not work properly on
Hyundais.

I'm not sure what the exchange rate is these dase, but the most recent
U.S. dealer retail price I saw for this item was around $65 to $70 for the
part.

Thanks, FX rate is about 2:1 so that's way less expensive than I have
been quoted. Would you know of an online supplier that could send
these from the USA ?
 
I don't know of any online suppliers, but others here have reported that
some dealers sell online. Before you do that, see if you can find the
Hyundai part number of the sensor you need. If you can give me the
number, I can tell you if it's available in the U.S.
 
I had a useful conversation with tech guys at Bosch (USA) and Airtex
(also USA). They both told me that the sensors are in fact identical
and Hyundai's two part numbers just reflect that they have differing
cable lengths attached.

I have not identified reliably what technology they are though.

A comparison table at
http://www.lambdasensor.com/main/general2.htm#hyunda
tells me that a generic 1190 part - a 1 wire Zirconium sensor is
compatible.

This table at :
http://home.att.net/~ngksparkplugs/wsb/NTK_OEM_Cross_Reference_Rev1.pdf
was more useful, providing the following details

HYUNDAI - 39210-37125 (RHS)
NTK - 25625
AIRTEX - 5S4212 / SU6204
BOSCH - 13746
WALKER - 250-24517

HYUNDAI - 39210-37165 (LHS)
NTK - 25625
AIRTEX - 5S4211 / SU6202
BOSCH - 13748
WALKER - 250-24517

*The Bosch tech suport told me it was a 4 wire Titania
*The Airtex tech support said it was 4 wire Zirconia
So I am still not sure of the tech but another call to Airtex/Bosch
would probably clarify that.

Anyway, my latest problem is that the garage has just told me that
they can't extract the bad sensor, it won't come out, their attempts
have started to round the profile of the sensor nut. Adding.
helpfully, that further attempts will involve removal of the manifold
and that would entail draining of the aircon and the bill will be more
than the car is worth! When I get the stamina I will ask if they let
the manifold reach a high temperature, but they may have dmaged the
sensor nut too badly at this stage.

Arghhhh
