Tire pressure light on but tires look fine — what gives?

Check your spare tire! The 2017 Accord has a TPMS sensor in the spare. If the spare is low (they lose air sitting in the trunk for years), it'll trigger the light even though all four road tires are fine. Fill the spare to 60 PSI (it's a compact spare, higher pressure is normal). Also, 32-33 is slightly low for an Accord — door sticker likely says 35 PSI.
