This P0141 code has been intermittent after changing the oxygen heater o2 sensor several times

Ford Windstar
The engine light came on after a couple of miles, the car do start,the car do not shake or run rough idle. I simply replaced all four oxygen sensors. However, the check engine light still come because the P0141 code seem to be stuck in the computer's memory bank. I need a fix!


Chrysler Pacifica
replaced catalytic converter and both oxygen sensors now I am getting a p0141 code and engine light came back on

I do not know where to connect the two white wires and the grey and black wire. The connector that was attached to the alternator is missing. I noticed several wires hanging from the alternator one white, yellow, green and black.
