P0336 to P0335?

Question

This is my second CPS and now a new connector too. Does the splice that joins the wires need to be sotered? Code was a P0336, after wiring in the new connector it\'s a P0335. It had an oil leak that got inside the connector, so it was replaced. I don\'t get it. If someone can\'t tell me what\'s up, it goes to the shop tomorrow!
