Diagnostic Reading HELP: Code P2238 on 2004 Camry 4cyl

My brother's 04 Camry just had a readout of Code P2238. His car has roughly 105,000 miles on it. A quick search in this forum gives a single mention of the code, but with no definite answer. Can anyone please help provide more answers as to what Code P2238 is and how to fix it? Thanks.

Diagnostic procedures are in the Service Manuals.

His GEN5 is probably similar to your GEN6 so you could look in yours.

He got it from an OBD reader purchased at Kragen or Autozone, I believe.


Diagnostic procedures are in the Service Manuals. Njerald, by Service Manual, are you referring to the Haynes Manual? If you are, we don't have that.

If anyone else has had this problem on their Gen 5, please share your experience. Thanks!

Check out the bottom of this page. Most often with this code your problem is going to be the AF sensor.

Oh haha! Guilty as charged. I've never bothered downloading that. Thanks for the heads up!

My brother and I finally figured out that it's the A/F sensor. Thanks!

oxygen sensors usually are designed to last up to 100k miles. get the replacement either Denso (factory) or NTK (made by NGK company).

if you want OEM (denso) go to online toyota retailer and look there by part number or go with NGK:
http://www.ngksparkplugs.com/part_fi...uv/default.asp

you can check toyota factory part number here (search for "oxygen sensor"):
http://www.toyodiy.com/parts/

get the NGK model number or OEM part number for your car and look for it on internet stores like rockauto.com or amazon.com
rockauto may carry denso parts cheap. amazon usually stocks ngk mostly at good prices. you may also try ebay, sometimes you can find real deals over there.

most local stores will charge you an arm and leg for A/F sensor.
