Either you have multiple sensor failures or your ECM is acting up and needs repair or replacement. If the indicators are for serious things I would get this corrected quickly.
Or your electrical system is simply breaking down due to age. It happens. Modern electrical systems are sensitive and do weird things when connections get weak, or dirty, or damp. I have 3 fifteen year old cars and one twenty-five year old one and they’ve all had issues simply related to weak electrical connections in the wiring harness. Start by cleaning and tightening everything up. Make sure the battery is strong. Then you’re ready to start following up codes and possibly replacing things. Without doing that first you’re jumping the gun. Good luck.
