You need more details.

Was the car running at the time?
Was it dead cold? Just shut off after 15 min's, 4 hrs?
Idling? Revved up?
(etc etc)

They all look 'close' to normal except for the coolant. That one alone will throw everything for a loop.

It's reading the one that goes sideways, just above the water pump, and below the filler neck.

I know that it's that one, and the car idles really high. It also said code
22 for a low tps sensor
