Multiple coolant codes + hybrid battery no charge; cause?

Hello,

The other day my wife went to the grocery store and on the way home the red triangle and christmas tree of dash lights came on. We had experienced this before, in 2017, when our hybrid battery went kaput. Had it replaced by the great folks at Atomic Auto, and we were back on the road. This time, she was able to drive the 1 mile to get the car home, and based on the MIL, MFD icon of car with exclamation point, and one bar of battery shown - in addition to the triangle - I thought for sure the replacement hybrid battery had given up.

Pulled the codes today and turns out, highly likely not the battery at all. It coughed up this mess:

- P0505 - Idle control
- P1116 - Coolant temp sensor out of range
- P1121 - Coolant control valve position sensor stuck
- P1123 - Coolant control valve position sensor high
- P1150 - Coolant path clog up for coolant heat storage system
- P3191 - Engine does not start

First thing I did was check fluids, and everything is spot on. Have a little over 220,000 miles and it eats a little oil, but I keep an eye on it. After pulling the codes, I cranked it up and it ran fine. Out of curiosity I cleared the codes, ran again and it started charging the hybrid battery normally; let it run till we were at 50%+/- battery graphically.

When I started the car, I did hear some slight gurgling around my feet/under the hood that I had never heard before. It cleared up quickly and didnt come back. Flow in the inverter reservoir is normal; bubbles go by at maybe a half-inch per second like they always have, and the inverter coolant pump hums/vibrates normally.

All roads seem to point to the coolant control valve, but would it cause the engine no start and subsequent no charge of the hybrid battery?

Thanks for the help!

Hello,
Thanks for the swift response! Ill definitely take you up on the offer to help if I cant get it worked out.

I hadnt thought about it as though the coolant issue was secondary, and primary(maybe even isolated?) was the battery low due to engine no start. Ill check the trouble areas of P3191 more closely and see what I can find.

Thanks!

Thanks yall!

Cleaned the throttle body and air flow sensor last weekend and everything seems to be running good again. Used the q-tip method with throttle body cleaner as recommended by a post here on the forum. Image below of how dirty it was; now clean, but of course forgot to take a photo : \

[edit: apparently I cannot add a photo until Ive posted more? just imagine the tb having oil residue all over it. Will post an image once I can for future reference]
