This is a DIY on a 2000 Infiniti I30 on how to replace the Idle Air Control Motor With Out Replacing the Valve .
You have to remove the air filter box because the idle air control valve is located under the throttle body - which has to hoses that the coolant runs through to keep your throttle body warm on cold days - remember to check all the hoses while your there -
There you will see the idle air control valve - but in this DIY we will be only removing the idle air control motor because the valve is OK - You will locate the two screws that hold the control motor - Once you remove the motor you will see some coolant come out do not panic that is OK - clean area out with brake clean before putting the new one in - make sure you know where the two screws came out because there are four holes and you want to make sure you put them back where the old holes were used - One you replace the control motor you need to put back the air intake box back together so that the mass air flow is connected so that you can do the relearning procedure below
BELOW IS THE LEARNING PROCEDURE YOU MUST DO
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.
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)
- Park/neutral position (PNP) switch: ON (Shifter in Park or Neutral)
- Electric load switch: OFF (Air conditioner, headlamp, rear window defogger)
- Steering wheel: Neutral (Straight-ahead position)
- Vehicle speed: Stopped
- Transmission: Warmed-up (Drive vehicle for 10 minutes.)
- 1Turn ignition switch "ON" and wait at least 1 second.
- 2Turn ignition switch "OFF" and wait at least 10 seconds.
- 3Start engine and warm it up to normal operating temperature.
- 4Check that all items listed under the topic PREPARATION (previously mentioned) are in good order.
- 5Turn ignition switch "OFF" and wait at least 10 seconds.
- 6Start the engine and let it idle for at least 30 seconds.
- 7Disconnect throttle position sensor harness connector (brown), then reconnect it within 5 seconds.
Wait 20 seconds.
Make sure that idle speed is within specifications. If not, the result will be incomplete. In this case, find the cause of the problem by referring to the NOTE below.
Rev up the engine two or three times. Make sure that idle speed and ignition timing are within specifications.
