SupraMan Posted January 23, 2007 Posted January 23, 2007 I can't find the data on O2 sensors. Does anyone know the band for 'in spec' sensor resistance in a 96 ES300? Can't find it anywhere on 5 pages of ES posts researched :cries: , not waiting for the engine light to tell me 'failed sensor' on a roadtrip. I know oxygen sensors degrade gradually over time/mileage, just wanted to check mine to see how far off spec they are. I did learn a lot from this post on the LS400 forum: http://www.lexls.com/tutorials/EFI/mainoxygensensor.html. 5.1 to 6.3 ohms is what the LS has. but of course that is a vastly different application in the v8 from ours. Thanks again guys for the assist!
