What’s the difference between an open and closed loop engine management system?
The main difference between an open-loop system and a closed-loop system is that the closed-loop system has the ability to self-correct while the open-loop system doesn’t. Consequently, closed-loop systems are often called feedback control systems while open-loop systems are also known as non-feedback controls.
What happens when the O2 sensor is shut off?
When it takes 15 minutes to go closed that means the heater didnt do its job and it only went into closed loop because the exhaust finally got the sensor to warm to its 600 deg. operating temp. So one of three things. o2 sensor heater core is bad, the o2 wiring has a short or some malfunction, or the o2 itself needs complete replacement.

What’s the resistance of the Toyota O2 sensor?
I tested the new o2 sensors resistance as stated in the Toyota shop manual (it is supposed to read 11-16) and the front one read 16 and the rear read 21 so I think I may have gotten sent a bad rear O2 sensor. I have found buying cheap brand name stuff on Amazon to be a fool’s errand sometimes.
