Default Why is there a thermistor in the power door lock circuit.

What would the role of a thermistor be in the power door lock circuit
of a car? It's in series with the door lock "motor", which might be
a solenoid or maybe a rotating motor.

Is it possible that it is meant to lower or turn off power to the
mechanism if the circuit is left closed for some reason and the
solenoid would otherwise overheat?

The symbol it uses for a thermistor is a resistor symbol in an
elongated circle, like a high school running track around the football
field. Is that the usual symbol for a thermistor.


Well this says the symbol is retcangle with the stick figure of a
hockey stick across it.

What's with Toyota anyhow? Are they wrong about the symbol, or maybe
they're wrong when they call it a thermistor!
