This is the one attached to the Throttle Body. Engine code says this is my problem. I would like to get a new one but I can't find it anywhere. I posted a similar thread in WTB Parts but had no response. Mazdatrix and British Victoria don't have them. I checked with Advance Auto locally and they don't have it. Does anyone know where I can get this?

 

Why is Mazda the last place anyone thinks of for Mazda parts?

Have you checked that it's definitely the sensor and not the wiring?
