16514 - Oxygen (Lambda) Sensor B1 S1 fault code

OkOn going problem with the EMLWhen I check the fault codes, i get 16514 - Oxygen (Lambda) Sensor B1 S1: MalfunctionP0139 - 008 Implausable SignalI clear the code and the EML goes out and car runs great from cold. After I have stopped and re start the EBL light comes back onI thought as i go over quite a view speed bumps that it might have been the plug. Disconnected the plug and re seated it.Same thing happens over and over againChecked the resistance between pins 3 & 4 and got 3.5 OhmsWhat else can i check to diagnose the problem?Thanks in advance

Go into Basic Settings 04, set the engine at 1800>2200 rpm and hold the brake pedal down, select group 030 and zone 1 should show 111 eventually. Then enter group 034 and click GO or ON, you may need to play around with the rpm to get the test to start saying “TEST ON” and eventually you will get B1S1 OK or FUBAR. Do the same in group 37.
