  4. Warm up the engine (engine coolant temperature of 80°C (176°F) or higher) with the A/C switch and all accessories off [A].
  5. With the engine running, drive the vehicle at a speed of 10 km/h (6 mph) or more [B].

     HINT:

     If the engine stops, further depress the accelerator pedal to restart the engine.

  6. Idle the engine for 20 seconds or more [C].
  7. Repeat procedure [B] and [C].
  8. Enter the following menus: Powertrain / Engine / Data List / Engine Speed and Engine Independent.
  9. Check the Engine Speed when the value of Data List item Engine Independent is "Operate" [D].

     Standard:

     Engine Idle Speed
     950 to 1050 rpm

     HINT:

     • Be sure to perform this step with the A/C switch and all accessories off.
     • Make sure that park (P) is selected.
     • If the value of Data List item Engine Independent is "Not Opr" when the engine is idling, charge control is being performed. Check the Engine Speed after charge control is complete ("Operate" is displayed).
     • If the idle speed is still out of the specified range, repeat procedure [B] and [C] until the idle speed is within the specified range [E].
• *4: Drive the vehicle for a short while after replacing the knock control sensor and check if knocking occurs. If knocking occurs, drive the vehicle until knocking stops.
