Pics?

What ever you do do not buy genuine Toyota parts on eBay.

 

Do you have the ebay link for the sensor you got?

 

I too like Invader would like to know what the link is or where on eBay you got the sensor. Thanks.

 

Here's the link : https://www.ebay.com/itm/DENSO-234-9052-OE-style-Air-to-Fuel-Ratio-Sensor-30-days-Warranty-NEW/391908191639?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649, I don't have pics... forgot to take some when trying to replace the sensor... can you recommend a legitimate parts retailer ?

 

You got the right one if it's a Denso as on the photo... It should fit.

 

I also agree it says it’s a Denso on the ebay link. So it should fit.

 

If it's just not snapping together sometimes the rubber seal gets dry and wants to bind up when you're re-connecting them. Some silicone grease rubbed on a paperclip and then rubbed around the rubber seal inside the connector will usually get them to go back together that last little bit so it snaps.

 

I'll try that... and I will take some pics for you guys... because it's just not snapping like you said Bitter...

 

done!

@Biiter I follow your instructions and voila! now it clicks ... here are a few pics

 

You'll find that trick coming in handy lots of other places around the car as well, it also helps to further weatherproof the connection by adding some highly water resistant schmoo.
