can you run a car without a temperature sensor

Do engines absolutely need an O2 sensor to function ...

· Yes, you will get a yellow check engine light but it will not prevent you from driving the car. Emissions will be worse with a failed O2 sensor (because closed loop control of the process is impossible so there will be either too much HC and CO or too much NOx depending on whether you have a lean or a rich mixture). So, based on this, the car can continue operating on the other sensors alone such as the air flow sensor. However, if both the air flow sensor and the O2 sensor …

Drive A Car Without a Thermostat: All You ... CAR FROM JAPAN

When running the car without a thermostat, it runs at 50o C temperature. At this temperature, the humidity gets packed in and condensed, which blend with the oil and results in slush. This leads to the situation that the slush blocks lubrication and the entire system wears out. For that reason, running a car with no thermostat is destroying vehicle performance.
