I had gotten the error code P0141 and changed the sensor and started the car and drove a while thinking my check engine light would shut off, but it has not. Then I noticed that my D4 light has not come on? What could possibly be the problem? And how can I manually reset the ECU?

I replaced the sensor cleared the code and drove half a block and the same code came back on? I had replaced the sensor & made sure that the plug was clean before I connected it.I also noticed that my car isn't quite shifting on time and it is shifting hard?
