1999 Mazda Protege 1.8 ES A/T - System Pressure Sensor/Switch - Code P0452

[LEM]

Hello,
I am trying to find the Location of the Evaporative Emission System Pressure Sensor/Switch on my car to replace it. The mechanic scanned my car and told me it was a code P0452 and I would need to replace this sensor.

I am trying to find it to see how it looks so that I can purchase it and replace it myself.

Sincerely and Regards,
