I'd have to agree with DOC. If you would like to be certain that it is the sensor conduct the following tests.
Disconnect the sensor and measure the three wires for voltage, one wire will have roughly 5V. This is the reference voltage to the sensor. Measure the two remaining wires for a Ground circuit. The third wire is the air flow position signal, the feedback voltage to the control unit. Now that you have an idea of the three wires and their purpose reconnect the sensor but leave the pins somewhat exposed so they can be probed with meter leads. With the engine running measure the feedback voltage signal, specification is approximately .5 V to .9 V. Happy motoring to you
