Im sorry to get back so late internets been out and the forum doesn't like my phone haha. anyways I'm getting P0134 p0154 p0156 I'm using an action CP914 I'm going to unplug them and plug them back in again after looking at them the harness don't look like they are connected all the way.

 

So i broke down and took it to a shop and they are also confused when they plugged in there snapon code reader and looked at live data all sensors had voltage and they cleared the codes and none are coming back but in their live data it shows the system as being open loop not closed loop and they are saying they can't do anything about that and that the ECU has to figure it out on its own. are they correct in this or am i just going to be in open loop forever with working 02 sensors?
