Does anyone know of any breakers yards in the UK that may have parts for an S2000? I have been trying to get hold of a pair of lambda sensors for a while without much success.

 

These are available for a later car...

Buying used, not sure it's worth it. Just get a decent branded one new.

Failing that integrastella breaks lots of S2s

 

eurocarparts lists 3 for an ap1 including 2 universals and one direct fit for the rear sensor, ranging from £60 to £85 for the bosch version. unfortunatly only the 2 universals for an ap2.

IMHO not worth risking used to save £20-30, particularly for a service item.

 

Rockauto seem popular
A thought,,,back one doesnt do much tbh,only tells you cat is fcuk,most people with TP/HFC will space them to avoid flow and stop cell anyway

 

The rear sensor from Denso can be had cheap off amazon but comes from the US -
Agreed it doesn't do anything though.

 

You can get the 2006+ primary sensor from Autodoc: https://www.autodoc.co.uk/denso/16176165 | I bought and fitted this a few weeks ago - it is identical to the sensor that I removed (both branded Denso). DENSO DOX-0517 is what you're looking for if you want to shop around. I got mine for £123 delivered but looks like they have gone up in price now - £138 just for the sensor.

Not sure where to find a secondary for a 2006+ as I haven't looked into it.

 

Thanks for the tips all. I managed to get hold of a primary sensor from RockAuto. It is a Denzo one that I fitted; however, I am still getting the engine warning light with the same error code - P1157 --> P2A00 O2 sensor circuit range / Performance Bank 1 Sensor 1. I wonder if it is the sensor I have fitted and if the one from Autodoc (Denzo DOX-0517) will sort the issue?

 

Bank 1 should be the manifold one, if you replaced it and it still doesn't work dunno..

 

What readings of mV do you get via OBD? It should be 0 for stoichiometric at idle. That error does suggest that the replacement sensor's output is still out of the expected range.
