I really need some help on my 2001 sequoia I’m having low voltage at slow down or stop signs and it will just cutt off I changed my alternator 2 times and figured I had a bad alternator and it’s not the problem , also I had a bad o2 sensor and I changed my 02 sensor and tried to connect it back to the electrical connector and it won’t click back in ,it stay in the plug but it won’t cliick in I don’t know if that’s the issue or is it something else , oh also there’s nothing wrong with the battery

I could really use some help

It is not clear what you mean when you say "it will just cut off". Do you mean the engine stops running? What is the voltage reading at when you believe it is "low"? How are you checking the voltage?

How do you know there's nothing wrong with the battery? Have you had it load-tested?

With regard to the O2 sensor connector, it's possible that the tab that keeps the connector clipped in broke. If that's the case and the connector vibrates loose, you could probably zip-tie it.
