Readiness monitor errors after engine swap on 2007 prius

I just completed an engine swap on my 2007 Toyota Prius with 300K miles. I got the new engine in fine, but got a catalyst monitor, evaporative system, and oxygen sensor readiness monitor error when I went to restart the car. Car will not start in this condition. My thought was that maybe some of the wiring got messed up during the swap. Are there any schematics of the wiring for the vehicle that would help me determine if some of the sensor signals aren't reaching the ECU? It would be nice to verify the cause before I go changing components.

 

I've used two OBD scan tools to check for errors. One is called DashCmd and the other one is called Torque. Using the torque tool I am able to see coolant temperature, battery voltage, and throttle position, so it seems like I'm getting comms. Neither tool is showing any fault codes. The status of the readiness monitors is incomplete, I guess because I had the power disconnected from the car. When I start the car I get the car symbol with the explanation point on the touch screen. Typically when you start the car you hear all of the relays engage and the car starts. I am not hearing any of those clicking relay sounds at the moment, just the immediate explanation point symbol. I have the car completely off the ground on jack stands at the moment.

 

Yes, I did have that disconnected while I was working. I plugged the connector back in upon completion and have tried removing and reinserting it. I also disconnected some cables from the inverter during the work but reinserted them. I didn't take out the inverter during the engine swap. The 12V battery looks good. I was thinking to try the Techstream tool to try to get some more detailed diagnostics.

 

Yes, I am going to try the Techstream tool from Toyota to try to find out what problem it has. The OBD tools I have on my phone (DashCMD and Torque) do not indicate any error. It will take me a couple of days to get the equipment, but I'll try it then.

 

I’ve loaded some of those I think. My hybrid battery went out this year and I was troubleshooting it with the Torque app. I used it to see the voltages of all the cells in the battery pack. I don’t know if there are some specific ones to download for this problem.

 

I’ll try reinserting the orange plug a couple more times using the technique you described. I think I may not have slid that top handle down.

 

I resolved this problem by making sure to follow the technique for inserting the hybrid battery safety connector as described above by mr_guy_mann.
