LEARNING PROCEDURE FOR IDLING IN MFI 
ENGINE

M1001011800102

PURPOSE

When the PCM is replaced, or when the learning value is initial-
ized, the idling is not stabilized because the learning value in 
MFI engine is not completed. In this case, carry out the learning 
method for the idling through the following procedures.

LEARNING PROCEDURE

1. Start the engine and carry out the warm-up for the engine 

coolant temperature to reach 80

°C or more.

NOTE: When the engine coolant temperature is 80

°

C or 

more, the warm-up is not needed if the ignition switch is in 
"ON" position once.

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

the engine.

3. After 10 seconds or more, start the engine again.
4. For 10 minutes, carry out the idling under the condition 

shown below and then confirm the engine has the normal 
idling.

• Transaxle: "P" range

• Operation in ignition-related, fan and attachments: Not to be 

operated

• Engine coolant temperature: 80°C or more

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