Hello all, I hope I posting this in the right section, my VSC TRC and the check engine light, and literally all my dash lights suddenly came on earlier this week. I used an OBD code reader and got several codes. I understand replacing the O2 sensor, but I don’t get how all the other sensors could fail at once. Has anyone else had this issue, and what did you do?

I had something similar happen with another Toyota model, and it turned out to be the battery causing all the dash lights to go off at once. Before going too deep into sensor replacements, try checking the battery and alternator health – low voltage can sometimes trigger all sorts of warnings. If that’s not it, you might want to look at any recent repairs or modifications that could’ve caused wiring issues. Maybe you can bring it to a shop to check?
I hadn’t considered the battery being the cause. I’ll check the voltage first and go from there. thanksI had something similar happen with another Toyota model, and it turned out to be the battery causing all the dash lights to go off at once.
