FULLY-CLOSED THROTTLE POSITION LEARNING FUNCTION OPERATION [L3 R.H.D.]

BUE014000000N12

Fully-closed throttle learning value (fully-closed throttle voltage) update

• If the calculated average value for the fully-closed throttle falls below the current fully-closed throttle learning value, the PCM updates the calculated average value as a new value.

• The average fully-closed throttle value is calculated by averaging several sample values that are detected when all of the following conditions re met (the throttle valve is considered to be fully-closed).

- No load with vehicle stopped (P or N range)

- If throttle valve opening angle has not changed

- Except during in test mode

- Engine speed less than 3,000 rpm

Inhibition condition of fully-closed throttle learning

• If any of the following conditions are met, the PCM determines that there is a fully-closed throttle learning difficulty and substitutes a set value (fixed value) for the fully-closed throttle learning value.

- During test mode (when connecting DLC terminal TEN to the body ground)

- Throttle position sensor malfunction (DTCs P0122, P0123 detected)

- Battery terminals reconnected

- If fully-closed throttle learning value exceeds the set upper limit.

- If fully-closed learning value decreases below set lower limit.
