Idle Stop Solenoid Replacement Service

What is the Idle Stop Solenoid all about?

Most older vehicles are equipped with a device called an idle stop solenoid that works to close off the throttle when the key is turned off. It prevents engine idle from continuing once the fuel and air stop being delivered to the engine. Fuel-injected cars don’t have this type of device. With fuel injection, the fuel goes to the injectors via an electronic pump, and the injectors are fired electronically, so when the key is turned off, there is no fuel delivery.

With a carburetor, there’s no electricity, so even when the ignition is turned off, the engine still rotates a bit, taking in air and fuel. Even though the car ignition has been turned off, there is still enough hot carbon in the engine’s cylinders to ignite a bit of fuel and create problems.

Keep in mind:

  • Idle stop solenoid inspection is not a part of routine maintenance.
  • A faulty idle stop solenoid can cause engine damage if not corrected.

Our recommendation:

If your car’s engine keeps going when you park, you may have a problem with your engine idle. Engine run-on can often be due to a faulty idle stop solenoid. If you’re experiencing related symptoms, get your vehicle checked out by one of our expert mechanics.

What common symptoms indicate you may need to replace the Idle Stop Solenoid?

  • Engine is idling too high
  • Engine sputters or shudders for a while after the key is turned off
  • Fuel economy is significantly worse

How important is this service?

If your idle stop solenoid is faulty and you experience engine run-on, it can be harmful to your engine because it interferes with the normal “cool down” phase. Your fuel economy will also drop. Have your idle stop solenoid replaced soon if it is deemed faulty.
