Бытует мнение что без консалта ничего нельзя сделать. Думаю что это заблуждение. Изучив мануал по Электройнной системе управления нашел много интересного.
После чистки впускного тракта (коллектора заслонки и т д ) необходимо выполнить следующие действия:
0. PERFORM ACCELERATOR PEDAL RELEASED POSITION LEARNING
1. Stop engine.
2. Perform EC-48, "Accelerator Pedal Released Position Learning".
>> GO TO 5.
5. PERFORM THROTTLE VALVE CLOSED POSITION LEARNING
Perform EC-48, "Throttle Valve Closed Position Learning" .
>> GO TO 6.
6. PERFORM IDLE AIR VOLUME LEARNING
Refer to EC-49, "Idle Air Volume Learning" .
Is Idle Air Volume Learning carried out successfully?
Yes or No
Yes >> GO TO 7.
No >> 1. Follow the instruction of Idle Air Volume Learning.
>>GO TO 0.
7. CHECK TARGET IDLE SPEED AGAIN:

Accelerator Pedal Released Position Learning UBS00914
DESCRIPTION
Accelerator Pedal Released Position Learning is an operation to learn the fully released position of the accelerator pedal by monitoring the accelerator pedal position sensor output signal. It must be performed each time harness connector of accelerator pedal position sensor or ECM is disconnected.
OPERATION PROCEDURE
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch ON and wait at least 2 seconds.
3. Turn ignition switch OFF wait at least 10 seconds.
4. Turn ignition switch ON and wait at least 2 seconds.
5. Turn ignition switch OFF wait at least 10 seconds.
DESCRIPTION
Throttle Valve Closed Position Learning is an operation to learn the fully closed position of the throttle valve by monitoring the throttle position sensor output signal. It must be performed each time harness connector of electric throttle control actuator or ECM is disconnected.
OPERATION PROCEDURE
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch ON.
3. Turn ignition switch OFF wait at least 10 seconds.
Make sure that throttle valve moves during above 10 seconds by confirming the operating sound.
Это мы обучили заслонку - на 25DD на 100% работает - проверено. А теперь обучаем холостым.
Idle Air Volume Learning UBS00916
DESCRIPTION
Idle Air Volume Learning is an operation to learn the idle air volume that keeps each engine within the specific range. It must be performed under any of the following conditions:
- Each time electric throttle control actuator or ECM is replaced.
- Idle speed or ignition timing is out of specification. PREPARATION
Before performing Idle Air Volume Learning, make sure that all of the following conditions are satisfied.
Learning will be cancelled if any of the following conditions are missed for even a moment.
- Battery voltage: More than 12.9V (At idle)
- Engine coolant temperature: 70 - 100°C (158 - 212°F)
- PNP switch: ON
- Electric load switch: OFF
(Air conditioner, headlamp, rear window defogger)
On vehicles equipped with daytime light systems, if the parking brake is applied before the engine is started the headlamp will not be illuminated.
- Steering wheel: Neutral (Straight-ahead position)
- Vehicle speed: Stopped
- Transmission: Warmed-up
For models with CONSULT-II, drive vehicle until “FLUID TEMP SE” in “DATA MONITOR” mode of “AT” (4-speed A/T) or “TRANSMISSION” (5-speed A/T) system indicates less than 0.9V.
For models without CONSULT-II, drive vehicle for 10 minutes.
Without CONSULT-II
NOTE:
- It is better to count the time accurately with a clock.
- It is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuit has a malfunction.
1. Perform EC-48, "Accelerator Pedal Released Position Learning" .
2. Perform EC-48, "Throttle Valve Closed Position Learning" .
3. Start engine and warm it up to normal operating temperature.
4. Check that all items listed under the topic PREPARATION (previously mentioned) are in good order.
5. Turn ignition switch OFF and wait at least 10 seconds.
6. Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.
7. Repeat the following procedure quickly five times within 5 seconds.
a. Fully depress the accelerator pedal.
b. Fully release the accelerator pedal.
8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MIL stops blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the MIL turned ON.
10. Start engine and let it idle.
11. Wait 20 seconds.
12. Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications.
ITEM SPECIFICATION
Idle speed M/T: 625±50 rpm
4-speed A/T: 700±50 rpm (in P or N position)
5-speed A/T: 675±50 rpm (in P or N position)
Ignition timing M/T: 15±5° BTDC
A/T: 15±5° BTDC (in P or N position)
Какие должны быть обороты и зажигание смотрите на табличке под капотом на 25DD 700 rpm и 17°.
По проблеме описаной в этой теме. после обучения заслонки, замены МАФА или одного из Кислородников - выполняем очистку SELF-LEARNING CONT
1. Start engine and warm it up to normal operating temperature.
2. Turn ignition switch OFF.
3. Disconnect mass air flow sensor harness connector.
4. Restart engine and let it idle for at least 5 seconds.м 5. Stop engine and reconnect mass air flow sensor harness connector.
6. Make sure DTC P0102 is displayed.
7. Erase the DTC memory. Refer to EC-68, "HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION" .
8. Make sure DTC P0000 is displayed.
9. Run engine for at least 10 minutes at idle speed.
Как очистить код ошибки в ЕКУ?
Переходим в диагностический режим 2:
1. Set ECM in Diagnostic Test Mode II (Self-diagnostic results). Refer to EC-71, "How to Set Diagnostic Test Mode II (Self-diagnostic Results)" .
2. Fully depress the accelerator pedal and keep it for more than 10 seconds.
The emission-related diagnostic information has been erased from the backup memory in the ECM.
3. Fully release the accelerator pedal, and confirm the DTC 0000 is displayed.
Все это работает на машинах до 2004 года точно - мануал за 2004 год.
на моей цифре май 2001 все это срабатывает.
Удачи.
