Learning Procedure for Idling in MFI Engine

LEARNING PROCEDURE FOR IDLING IN MFI ENGINE

PURPOSE

When the ECM [M/T] or the PCM [A/T] is replaced, or when the learning value is initialized, the idling is not stabilized because the learning value in MFI engine is not completed.
In this case, carry out the learning method for idling through the following procedures.

LEARNING PROCEDURE

1. Start the engine and warm-up the engine coolant temperature to 80°C (176°F) or higher.

2. When the engine coolant temperature is 80°C (176°F) or more, additional warm-up is not needed if the ignition switch is in the "ON" position once.

3. Place the ignition switch in the "LOCK" (OFF) position and stop the engine.

4. After 10 seconds or more, start the engine again.

5. For 10 minutes, idle the engine under the conditions shown below and then confirm the engine idles normally.

- Transaxle: Neutral (P range on vehicles with A/T)
- A/C and other ignition-related items: OFF
- Engine coolant temperature: 80°C (176°F) or more

NOTE:
When the engine stalls during idling, check the dirtiness (on the throttle valve) of the throttle body and then perform the service from Procedure 1 again.

INITIALIZATION PROCEDURE FOR ETV

When the battery cable is disconnected and reconnected, ETV value (Fully closed position) is eliminated, so that the throttle valve opening angle control would not be performed correctly. When the battery cable is disconnected and reconnected, initialize the ETV using the following procedure.

1. Turn the ignition switch to the "ON" position and then, place the ignition switch in "LOCK" (OFF) position.

2. For 10 seconds or more, keep the ignition switch in "LOCK" (OFF) position.
