Idle Air Volume Learning: Preparation

Before performing idle air volume learning procedure, ensure 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 12.9 volts at idle.
• Engine coolant temperature: 158-210°F (70-99°C).
• Transmission: Park or Neutral.
• A/C, headlights and rear window defogger: off.
• Headlight switch: 1st position (only on vehicles with daytime running lights).
• Steering wheel: straight-ahead position.
• Vehicle speed: stopped.
• Transmission: warmed up. If using CONSULT-II on A/T-equipped vehicle, confirm FLUID TEMP SE in DATA MONITOR mode of A/T system indicates less than .9 volt. If not using CONSULT-II, drive vehicle for 10 minutes to warm up transmission.
