I got around to getting a new CPS. It came a Hella box with MB part number on the box of 003-153-2828, I believe that is the correct number. The sensor itself has the number and manufactorname ground off, it only says made in Germany.

I test the new one with an ohm meter and it measured 664 ohm applied heat with heat gun and it slowly went to 725 ohm.

When I tested my old one it measured 1148 ohm applied heat and it quickly went to 1250 ohm.

Are the ohm readings supposed to be different for the new CPS?
