Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Air Induction
Air entering the engine flows through the air vane meter. The air vane meter measures air flow and temperature for the ECA which uses the information to assist in determining air/fuel ratio.
The air flow is then directed to the turbocharger (2.3L only) and the throttle body. The throttle body controls air flow to the engine through a single, butterfly-type valve.
An air by-pass channel is incorporated into the throttle body to satisfy both cold and warm idle airflow requirements when the throttle valve is in a fully closed position.
Airflow through the by-pass channel is controlled by the air by-pass valve which is mounted directly to the throttle body. Air by-pass valve function is controlled by signals from the ECA.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
