Correct O2 Sensor?
 

I need to replace my right side post catalytic converter O2 sensor due to a P1117 code. I ordered a Walker O2 sensor from OxygenSensors.com. The connector for the Walker sensor is not identical to the one on the Porsche sensor that I will be removing. I've attached pictures. Since they won't accept the return of an O2 sensor after it has been installed, I don't want to proceed unless I'm absolutely sure that I have the correct sensor. Naturally, they are closed on Saturday.

Has anyone installed a Walker sensor on their Boxster? It looks like the Walker connector will fit around the connector on the car while the Porsche sensor fits inside. The Walker part number on the box is 250-24423 which according to the company's web site is the correct part for this application.

I think you need to get walker part number: 250-24647 which has the same connector as your existing o2 sensors.

The connector on the new o2 sensor you got looks the same as the connector on the o2 sensors for my car (1999 2.5).

Both part numbers, 250-24423 and 250-24647 are listed as being able to fit your car, but perhaps there was a mid-year change and some 2000's need the first one and others need the latter.

Good luck,

I think you are correct. Here's what Tool Pants told me on RennTech:

There might be an error with the Walker application guide catalog, where you look up Walker part number by the vehicle. In this Walker catalog 250-24423 is shown for the rear sensor for a 2000 Porsche Boxster. If this is a Walker error then it will be repeated by oxygensensors.com

PET has the rear sensor as Porsche part number 986-606-128-01. Using the porsche part number on the Walker oem parts interchange catalog the rear sensor comes back as a Walker 250-24647. The front sensor also comes back to the same 250-24647 number.

I think you need 250-24647 and the 250-24423 is a Walker catalog listing error that got repeated by oxygensensors.com.

Oxygensensors.com sent me a 250-24647. I put it on today and it fit. I disconnected the battery to clear the CEL and took the car to Autozone for a reading. I don't have a P1117 code anymore, so things are looking good now.

I hope that others can avoid the confusion I encountered. I wonder if Walker will update their catalog.
