Yes the O2 sensor preheater problem will turn on the VSC light, see the complaint often, why? don't know
.P0031 TOYOTA - Oxygen Sensor Heater Control Circuit Low Bank 1 Sensor 1
In most cases the O2 being replaced cures the code but here is the full story.
Possible causes- Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 circuit open shorted to ground
- Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 circuit poor electrical connection
- Faulty Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 circuit
- Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 circuit fuse
- Faulty Engine Control Module (ECM)

Code p0420 on 97 lexus es300


P0420 is catalyst below threshold. It is triggered via the rear o2 sensor (post cat), so you may want to check that sensor to make sure it's functioning properly.
