is there any way to check the map sensor . i really cant afford a new one so if there is a way to check it before i just go out and blow 70 bucks on a new one it would be much appreciated

 

P0107 Means your sensor has a low voltage input, something with the sensor or the wiring is going wrong. Look below on how to test your MAP sensor

1. Check the MAP sensor for any dust or debris on the sensor. To do this, flip the sensor upside down and visually inspect the sensor wires. Make sure that the sensor wires are free of any contaminants.

2. Set the dial on the voltmeter to "Ohms" and check the resistance between the THA and E2 terminals (check your vehicle's service manuals for the exact location of these terminals on your MAP sensor). Insert one of the leads on the voltmeter into the THA terminal, and another lead into the E2 terminal. The output on the readout should be at or near 0.

3.Turn the ignition switch to the "II" position.

4. Set the dial on the voltmeter to "volts," and touch the red lead on the voltmeter to the VG terminal on the MAP sensor and black lead on the voltmeter to the E2G terminal on the MAP sensor.

5. Gently blow into the sensor's wires and check the voltage. It should fluctuate. If it does, the MAP sensor is functioning properly. If it doesn't, your MAP sensor has failed and must be replaced.
