Did I Buy the Correct O2 Sensor?

[KevinH90]

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.

As is probably pretty obvious to you, you have the wrong sensor. The pic on the right shows a sensor for an earlier boxster.

I don't know because I have a 1997 2.5 and have not paid attention to the oxygen sensors used on the e-gas cars with the starter cat on the manifold.

On the 1997-1999 2.5s all 4 sensors are identical, including the connector. I also recently bought a Walker 250-24423 for my 2.5 and the connector on the Walker sensor is the same as the oem Bosch. Looks just like your second picture.

The Walker catalog for a model year 2000 has the pre-cat as 250-24647 and after the cat 250-24423. When I looked at their catalog for my 2.5 sensor I was suprised to see that a 2.5 (250-24423) sensor had an application on an e-gas car. I actually thought it was because the wires on an e-gas sensor where longer than the 2.5 sensor - did not think the connectors could also be different.

On the 2.5 sensor there is a lock on the connector. You need to slide the lock open to remove and mate the connector.

When I look at PET for the Porsche part number for the 2.5 sensor does not have an e-gas application.

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.

Thanks guys. I'm glad I stopped to think before I went too far.

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.

Thanks for the info. My car is over 60,000 miles now and I expect to have replace O2 sensors soon.
