Code P0057 - Needs an o2 sensor, anyone recommend a specific replacement?
So my 2003 S-Type R has code P0057 - Heater Control Circuit Low - Bank 2 Sensor 2.
So this is the secondary/downstream o2 sensor on the right side/passenger side of the engine, correct?
I checked the fuses under the hood related to the o2 sensor heater's and they check out fine, so it's safe to assume the o2 sensor itself is up for replacement? Nothing physically wrong with the sensor as far a I can tell.
I am going to order the sensor on rock auto, just wondering which one to go with, if anyone has any suggestions which one may be the best OE replacement.
There is DENSO Part # 2344798 described as "OE manufacturer" and is cheapest at $62.
There is also BOSCH Part # 15626 described as "EXACT FIT 4 WIRE HEATED" and it lists for $77.
Wondering out of these two should which you guys would recommend, thanks!

If it was me. I would swap the O2 senor I think is bad to the other side before buying anything. The sensor code better follow that move or you have a different problem.
It's kind of weird but with all the 100's of thousands of miles I have driven. O2 sensors are extremely rare to go bad.

Regarding o2 sensor longevity, I would say the same, however, in this particular case, it's the 'heater' element of the o2 sensor that appears to have failed. Using my OBD scan tool, I can see (once at operating temperature) the sensor itself is operating and reading fine; the heater circuit however appears to be either open or shorted, causing this trouble code. I also consider the fact my STR has custom downpipe's with high flow cat's, so perhaps that's in some way related to what could be considered an early demise.
Good advice with the sensor swap to rule out wiring or circuit troubles, but not sure if its worth the effort in this case.

Swapping would be good if it were easy (here, they tend to rust/weld in). You can see from JTIS etc that the downstreams are the older type, which are generally substantially cheaper than the newer (linear aka wideband aka AFR) type. Under no circumstances fit the wrong ones or the PCM will be unable to cope.

Precisely my thoughts regarding removing old o2 sensors, not sure if I want to go through that trouble just to confirm an obvious suspicion. Think I'll pass, and just order, install and cross my fingers.
Mostly wondering which manufacturer o2 sensor people recommend or feel are best OE replacements, thanks.

I replaced the rear O2 sensor drivers side a couple of years ago. I replaced it with a Denso I got from rockauto. I had to clip the conector of the old one and sauder it on the new one. Worked great and I think I got it for under $30. But the rear one was easy to get to. The old one came off fine...

As an update, I ordered and received the Denso downstream 02 sensor.
Came with connector, so no soldering needed, and was a straight forward replacement.
Sad news is my CEL came right back, and code p0057 is still present.
I suspect it might have something to do with the ground/body of the sensor itself when threaded into my downpipe, so I'm going to try addressing that and report back.

Sounds like you changed the O2 sensor on the wrong side - put the one you removed back in that spot and change out the other side...

Ugh... You know what, you might be very well correct... Bank 2 I think is in fact the driver's side (LHD) of the engine... man glad someone was here to point this blunder out to me,
think i'll go under the car again tomorrow and do a quick swap...
thanks!
