Prius DTC 3190

Hi. First time posting so please bear with me. I have a 2010 Prius that needed some serious attention. I had to replace the transmission damper clutch, so I pulled the engine, replaced the damper clutch, replace the head gasket (head job and valve job), and put it all back together (I think). I am now pulling the following codes: p3190 with a “Check Hybrid System”. The hybrid battery is almost zero at this point just from sitting and me starting and stopping the car. I was getting p 2135, p0302, p0121, p0123 before, so I replaced the throttle body. That doesn’t seem to fix the problem. Are there any thoughts of what else to look at? Thanks.

 

Problem solved. Mass flow sensor!
