OEM doesn't mean the part is good anymore in my experience.
I came to Cummins to buy NoX inlet sensor awhile ago. Salesmen was searching something in his computer almost one hour then gave me NoX outlet sensor. I asked him why my old sensor wires wrapped in heat shield and this one is not. He replied it's a new style sensor. I was so naive to trust official Cummins salesman. Sensor looks absolutely the same except electrical plug has small difference. Lost my weekend to turn the sensor back and got what I need.
Another case. Volvo tie rod ends from Volvo dealership $ 180 each in plastic bag and paperwork in Chinese language. No any word in English or any other language. They were last 3 months.
The swamp is everywhere.

The moral here is to exercise common sense and do your due diligence research wise when sourcing parts.

The whole purpose behind replacing sensors is to give the computer accurate readings so that it can do its work of managing those systems properly.

Choosing to buy knock-off Chinese sensors, which could give out of range readings or fail in any number of unpredictable ways, is not worth the relatively small amount of money 'saved' vs going with OEM parts IMO.

And never trust parts desk monkey. They will sell you what they have in stock without clue the same sensor with different manufacturer number could have different characteristic curve and ECM calibration need to be updated. If manufacturer name and part number from the old sensor doesn't match to one they try to sell I wouldn't buy it.
