Codes P3190, P3191 after replacing EGR cooler, egr switch, intake manifold

I spent 9 hours replacing the egr system and the intake manifold. When I started the car, it said there's a problem with the hybrid system, and threw P3190 and P3191.

Any idea what I did? I'm a little deflated. I thought I could do this. I clearly made a mistake.

I left it at the diy garage overnight.

 

Yeah. I did some of that last night before the shop closed. I'm going back this morning. Maybe fresh eyes will help me spot the problem.

 

I had left a vacuum hose disconnected. I fixed that, but it's still throwing the codes.

 

It wasn't before I connected the vacuum hose. Then it ran until the hybrid battery was sufficiently charged, and when it shut off the engine it sputtered briefly until the engine was off.

 

It runs smoothly until I need to stop, then sometimes it sputters to a stop. When I was pulling in the driveway, it sputtered hard. No check engine light or error codes.

 

I bought a used cooler from eBay. The valve was new from Toyota, as was the intake manifold.

 

Update:
I was going through the box of detritus from the replacement work and I noticed there was a gasket still new in the packaging. I know that is not a reusable part, and I found the old one in the box as well.

I installed that, and took it for a test drive. The rough sputtering stops are gone, but the check engine light is on again. It drives well, but periodically it revs the engine very high when the electric motor is engaged or when the car is stopped. Despite the engine revving up, the hybrid battery isn't being charged.

I looked up the codes, but I don't remember the specific codes. Perhaps one was 107. I do recall the codes were about MAF or maybe MAP sensors.

I asked Claude what could be the problem, and he said I should reset the sensors to the default settings by disconnecting the 12v battery in the trunk. He said it will run like crap for a few minutes, but the system will adapt quickly to the new normal and should start working again.

I vaguely recall seeing similar recommendations on this forum, and I even saw him scouring a thread on this forum while he was "thinking".

I mention this because I know a lot of forums block AI for sucking down bandwidth and stealing data for training. In this instance, it did lead a legitimate user to the thread in question. I'm certainly glad this forum hasn't blocked Claude when he's helping troubleshoot a problem. I don't blame webmasters for blocking the wasteful training indexes, but it has been very helpful as a Claude user. Since Claude makes mistakes, I wanted to ask the biological collective your opinions.

 

0102 and 0113 were the codes from last night. I asked Claude, and he thinks there's a problem with the connector coming from the air intake box. I did have to take that off repeatedly during my troubleshooting. I'll check the connector when everyone is awake. I can't venture into the garage without waking my partner.

Am I on the right track? I appreciate all your advice. I know I've made some newbie mistakes. I am sort of a newbie. Until recently, I didn't dare do more than an oil change and swapping a damaged bumper.

 

I did connect it, but I manhandled it a few times. I probably broke it, or maybe bent some pins. I'll check. Thanks for your help.
