Replacing rear oxygen sensor

Fubaru · 02-23-2004, 04:58 PM

Looks like I need to replace the rear O2 sensor on my MY02 WRX
Local dealer wants $207 to do it.

How much labor is it to replace this thing? Is it plug & play with the existing wiring?

You can get a new sensor for $117 from www.subaruparts.com. It's easy to replace, just disconnect the plug and unscrew it and replace. If you want to save the $90 then do it yourself.

Thanks for the info...

I found these part numbers at that website:

22690 SENSOR ASSEMBLY-OXYGEN 22690AA501
22690 SENSOR ASSEMBLY-OXYGEN 22690AA490
22690 SENSOR ASSEMBLY-OXYGEN 22690AA540
22690 SENSOR ASSEMBLY-OXYGEN 22690AA420

They appear to be the same part. Does anybody know if this is indeed the rear oxygen sensor on the 2002 WRX ?

If you look to the right of the line items on the site, it tells you what it fits. http://www.subaruparts.com/diag/?mod...category=440-1 If you have a manual, then get the MT.205 part. If you have auto, then get the WRX.AT.205. The one for 251 is for a 2.5 liter engine either in the 2.5RS or STi.

Check your warranty; it might be covered by the emmissions control warranty.

The O2 sensors are part of the emissions control and should be covered to~80,000 miles. Check your owners manual. Ed Hayes

I will check into the warranty coverage.

I might be out of luck since I have replaced the entire exhaust except for the muffler - uppipe, downpipe, midpipe.

The rear O2 sensor that apparently went bad on my car is on a Godspeed downpipe.

i called a subaru dealer in my area today and they said the o2 sensors are only covered under the 36000 mile warranty (might be 30000 i forget). im out of luck too because my rear 02 just went out yesterday.

You do realize that this post is almost 2 years old right?

One would assume that after 2 years, the OP would have already found the answer to the question.
