What sensors can cause stalling?

Some of the most common sensors responsible for engine stalling include the engine coolant temperature sensor (ECT), mass airflow sensor (MAF), and throttle position sensor (TPS). Additionally, issues related to a vehicle's throttle body or idle air control valve (IAC) can also induce a stalling condition.

Can a bad knock sensor cause stalling?

A knock sensor, even if faulty, can not cause hard starting or stalling. To have your hard starting, as well as stalling issue, diagnosed, the recommended service is a hard starting diagnostic.

Does stalling the car damage it?

Stalling the car extremely frequently especially with load(passengers) can put additional stress on the transmission components but again its highly unlikely you will kill the car with stall.
