Good evening,

I attached a picture for you of the sensor.

Why are you replacing it? If you have a code, can you give me the code so I can verify if the sensor is bad?

Okay, I attached a flow chart for you to view and some testing to be sure it is the sensor.

The one thing I would do is remove the connector from the sensor and use a voltmeter and test the voltage at the sensor. Use the red lead in one terminal and the black lead to the other terminal. Then tell me the voltage reading with the key in the on position.
