Why is my auto engine idle stop not working?

There could be several reasons why your car’s idle stop may not be working. One possibility is that the idle stop sensor may be malfunctioning.

If the sensor is unable to determine the car’s idle speed, it may stop the engine to prevent it from idling in neutral. If the sensor is not malfunctioning, but the idle stop switch is not working, the car may still idle at a lower speed than intended, preventing it from stopping at the desired idle.

Finally, if the idle stop switch is working but the engine is not idling at the desired speed, the switch may be set too high or too low. If the switch is set too high, the car will idle at a higher speed than intended, preventing it from stopping at the desired idle.
