The following instructions describe how to conduct the Control the Injection Volume for A/F sensor operation using the Techstream. Connect the Techstream to the DLC3. 1. Start the engine and turn the Techstream on. 2. On the Techstream, enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Injection Volume for 4. Perform the Active Test operation with the engine idling (press the RIGHT or LEFT button to change the fuel injection volume.) 5.
