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.
Vane Air Meter Assembly
The vane air meter assembly is mounted on a bracket just below the air cleaner in the lower right corner of the engine compartment. The vane air meter contains 2 sensors that furnish input signals to the ECU. See Fig 1 .
The vane air meter assembly consists of an airflow sensor and a vane air temperature sensor. The vane air meter measures the volume of airflow to the engine. Airflow through the body moves a vane mounted on a pivot pin. This vane is connected to a variable resistor (potentiometer) which in turn is connected to a 5-volt reference voltage. The output of this potentiometer varies depending on the volume of air flowing through the sensor.
The temperature sensor in the air vane meter measures the incoming air temperature. The air volume and temperature inputs are used by ECU assembly to compute fuel flow (injector pulse duration) necessary for optimum air/fuel mixture. See Fig 2 .

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.
