Help needed sourcing a part

bainbridge · 5 Aug 2020 at 14:12

My 2009 mx5 is displaying fault codes which indicate a faulty upstream o2 sensor, but I can't find one anywhere.

Mx5 parts sell one for the mk3 but it's only for models up to 2008 and my car is a mk3.5 2009 onwards.

Ecp sell one sensor but it appears to be the downstream one, I need the upstream, pre-cat one.

If someone could direct me to one I'd really appreciate it.

Thanks

Not sure if you need rear or front but maybe this.

Plenty more on eBay.

Upstream = precat = front one, are there any reputable sellers to be recommended?

Well I've never had a problem on eBay but you will only generally get 30 days return policy from the seller although the actual parts may come with their own warranty.

I have a lot of faith in eBay from using it over last 15 years but many seem sceptical. You will have some level of risk.

Cheers, found one on the bay for £130, front is much dearer for some reason, I'll also get some front brake pads too fron the same seller, they still have 20% meat left but I like to get all my maintenance done in the warmer months.
