DIY : changing the Oxygen / O2 sensor on Yaris hatch MANY PICS - Toyota Yaris Forums

i recently changed my 2006 Mk2 Yaris 13. Terra (120.000km) upper side oxygen sensor.

The engine light was on for the last 5 years and checked with the service, confirming it was faulty oxygen sensor. Toyota dealer asked around $300 for the change.

Then after tons of research i bought a matching Denso sensor (DOX0109) that was similar to the original one without the socket. It had bare wires and connectors inside. You need to cut the existing socket and swap it on to the new one. Even the wire colors are the same.
I put it and yes, it works perfectly.

It all cost around $45 Now the fuel consumption is as good as new. Like 1-2 litre/100km difference with the new one.

So take it as a spare if you find. You'll need it.
Also the car had emission problems, i hope it's also fixed. I'll see in the next inspection.
