Covid Code

I am hoping some of you out there still have some data about Gen 1 codes.

This car hates to sit, and we haven't driven it much. 12v batt got low and it's throwing a fit. Right now it's got a Triangle of Death and it would be nice to clear it. Seems to run fine even with the Triangle. Got about 144K on it. Nice car. Hate to throw it away.

Here are the codes I got. Please check to see if you can add-to or improve the diag:

P3000 Battery Control System (Seen this lots. Probly related to it sitting. Not too worried about it. Replaced hybrid batt. recently)

C1215 Low Power Supply Voltage in Linear Solenoid (Which linear solenoid? Like an ABS actuator?)

C0200 Front Speed Sensor RH Circuit (Would this give me a Triangle? Same happened with LH)

C0205 " for LH

C0152 O2 Circuit

C1930 Open Circuit in Front Metal Board Temperature Sensor (Got this description from BlueDriver. Maybe just a low power error like a lot of these other codes?)

C1551 IG Power Supply Voltage (12v IG supply input of power steering ECU)

P3009 High Voltage Power Short Circuit (as above, this could be a blade leak, but I'm not going to worry about that)

All these can be cleared by BlueDriver, but the Triangle comes back. Please let me know if you have some data on these codes.
