Front Lambda Oxygen O2 Sensor 2S6A9F472BB For Fiesta Focus Fusion Mondeo KA

Used this to replace an oxygen sensor in a 2006 ford fiesta. The old one was very difficult to get out, corroded and stuck...nearly 20years old. Needed to use a specialist socket with some RP-90 penetrative oil. Spray on bolt, give it 10mins and the old one popped out with a bit of force. The new sensor seems to work no problems...and got the car through the MOT with no warning light showing. Relatively easy job, lots of YT videos out there to walk through the process. Happy days, saved a good amount of money on a garage doing the work.

Dead easy to install. if you have engine management light come on (EML) but car drives fine, more than likely this has failed. You will need an open end lamda sensor so ket removal tool though to remove this and replace said sensor.

My old one was giving me a bank 1 sensor 1 circuit fault. It came out really easy as opposed to all the horror stories I had read. Quick tip. I Soaked the sensor bolt in GT85 the day before I changed it, it had a good 24 hour soak. Then on the day re-apply some more penetrating spray, give it 10 minutes and start the engine. You will see the spray start to smoke, this is when you should turn of the engine and start removing the old sensor. The heat created by the short idling of the engine should have warmed up the manifold to expand the thread just enough. It will be in tight so give it a good push, when it releases unscrew in half turns to avoid damaging the wire in case you need to put it back (if the new sensor is faulty...it happens!! ). My sensor seems to be working fine (Fiesta 2005 Zetec climate). Will update if things change. Good luck (UPDATE) Sensor failed 15July 2020

I was a little dubious buying this as it was so much cheaper than anywhere else. Glad to report that it did the job and the car past it’s MOT first time

Item came promptly and there so far has been no issues after installing this part.

The car is 14 years old and didn't want to spend to much. Cheap replacement and MOT passed so good value for money

Worked for a couple of months then died. And that was through lock down. Very few miles. Avoid.

Perfect fit,quick reply and delivery,excellent x
