I did tha same thing back when NGK/NTK said they were discontinuing the line.
Guys, thanks all for your help and comments. This what rockauto offers for my 2.5l, i dont like that Walker offers the same sensor for down and upstream, i think the purpose is definitely the same for these sensors, so i would like to ask your opinions. And also, it seems Delphi has potential?
They are litterally just temperature sensors. Many times different part numbers are assigned to identical sensors with the only difference being the length of the wire between the sensor and the plug, or perhaps a slightly different plug..
My guess is that the Walker just decided to kill 2 birds with 1 stone (so to speak)...
Can confirm, I drove it the last 2 days without issuesWatch, I'll drive it to town tomorrow and they'll all 4 set codes off

Hey guys, I just got the P0138 code. O2 Sensor Circuit High Voltage (Bank 1 Sensor 2)
I'm not having any luck finding the NGK / NTK replacements. Does anyone still have a good source for these?
Edit. Found the right post on here and looks like the Denso 234-4078 is the correct match for the downstream sensor.

Rock Auto is showing both Walker sensors in stock but I'm going with the Denso since that seems to have given good results.
Still trying to find the correct Denso upstream sensor part number.

If you have read all the posts you'd have seen that others have been seeing good results with Walker sensors too... Food for thought.

Yes thanks. I'm slowly making my way through the 40 pages. I'm ordering the other Walker from Rock Auto
