Detach the air duct from the throttle body

Next, unhook the air supply hose that leads from the air filter to the throttle. It's usually held in place by a clamp, but other attachment methods may be used - ensure it's properly disconnected before removing it.

Disconnect the hoses and sensors that are connected to the throttle



Several wires and pipes are linked to the throttle body. Some of these are sensors, while coolant runs through the tubes. When detaching the pipes, be sure to position them vertically and plug them with a spark plug to prevent any fluid leakages.

Label all sensors and hoses

After cleaning the throttle body of your Ford Ranger, you'll need to reassemble everything, and with an array of wires, it can be quite a task. Thus, label and mark everything you disconnect, ensuring you remember the exact positioning and can reassemble everything correctly post-cleaning.
