The 2001 Ford Explorer Sport Trac features an recent engine that constantly monitors disparate components to flow efficiently. The Bulk air flow sensor monitors the immensity of air flowing nailed down the air intake process. The sensor then alerts the vehicle personal computer and the pc uses the info to halt how even fuel is needed for maximum efficiency. The Bulk air flow sensor is an electronic Element and can fail to perform properly causing the engine to race Rugged. The sensor can be tested using a voltmeter to bias provided it has failed.
Instructions
1. The voltage should read 0.5 to 0.7 volts during idle.4. Increase the engine speed using the throttle body or have an assistant depress the gas pedal.
Connect the negative voltmeter lead to the connector pin labeled "Ground." The meter should show close to 10 volts.
3. Reconnect the sensor wiring harness and use straight pins to probe the wiring with the sensor connected. Start the engine and measure the voltage with the voltmeter. Turn the ignition explanation to the "On" position, on the other hand achieve not initiate the engine. Agape the hood and fix the Bulk air flow sensor near the air cleaner.2. Unplug the electrical connector from the sensor and allot the connector pin labelled "B+." Connect the convinced voltmeter front to the B+ connector pin.
The sensor voltage should increase to 1.5 to 3.0 volts when the engine is higher than idle.
5. Check the wiring harness for damage from the sensor to the computer module. If you do not find damage, the sensor may require additional testing at a dealership service department or automobile repair shop using specialized tools.
