Here's the service manual methods for resetting the ECU, accelerator pedal released position learning, throttle valve closed position learning, and idle air volume learning. I don't think you need the throttle valve close position learning since your throttle uses a linkage cable and not by wire, but I threw it in here anyway for anybody else who may need it. Timing is somewhat critical on the following steps, I recommend using the one-one thousand method of counting. If you do not time the idle air volume learning properly, you may get the MIL and you will have to reset the ECU and start over.----RESET ECU (easier method below, I recommend it over this method)----
1. Confirm that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds.
2. Repeat the following steps (2a and 2b) procedures quickly five times within 5 seconds.
2a. Fully depress the accelerator pedal (HARD).
2b. Fully release the accelerator pedal.
3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the CEL starts blinking.
4. Fully release the accelerator pedal (while the CEL is still blinking).
5. Wait about 10 seconds.
6. Fully depress the accelerator pedal and keep it for more than 10 seconds.
7. Fully release the accelerator pedal (The CEL light will continue to blink).
8. Turn ignition switch to “OFF” position and now you can start the car. The CEL light should be gone.
If the CEL light continues to remain ON, repeat the above steps. Timing is EXTREMELY critical to resetting the ECU.
---- EASY METHOD ----
1. Ignition "ON", count to 3.
2. Depress/Release pedal 5 times...hard and fast.
3. Count to 10 (not 7!) and fully depress pedal
4. Count to 12 (SES should be blinking), release pedal
5. Count to 10, depress pedal
6. Count to 10, release pedal.
7. Turn off ignition, then start engine. Done!
---- Accelerator Pedal Released Position Learning ----
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.
---- Throttle Valve Closed Position Learning ----
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.
---- Idle Air Volume Learning ----
NOTE:
Before perform “Idle Air Volume Learning”, make sure that “Accel-
erator Pedal Released Position Learning” and “Throttle Valve
Closed Position Learning” are completed.
If not, perform “Accelerator Pedal Released Position Learning”,
EC-81 and “Throttle Valve Closed Position Learning”, EC-81.
1. Start engine and warm it up to normal operating temperature.
2. Check that all items listed under the topic “PREPARATION” (previously mentioned) are in good order.
3. Turn ignition switch “OFF” and wait at least 10 seconds.
4. Confirm that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds.
5. Repeat the following procedure quickly five times within 5 seconds.
1) Fully depress the accelerator pedal.
2) Fully release the accelerator pedal.
6. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MIL stops blinking and turns ON.
7. Fully release the accelerator pedal within 3 seconds after the MIL turned ON.
8. Start engine and let it idle.
9. Wait 20 seconds.
10. Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications.
11. If idle speed and ignition timing are not within the specification (750rpms +/-50rpm), “Idle Air Volume Learning” will not be carried out successfully.
Let me know if this works for you!
