So I have been troubleshooting the code p0452, and this is what I have found. The sensor itself was replaced but there is no voltage at the sensor. I traced it to the connector in the trunk, and still no voltage. It is reading .07v on the gray wire going to the trunk connector, it should be reading between 3-5v. Is there a common wire failure or connection that fails on these vehicles? I have not tested the output from the pcm yet and the wires look fine from the passenger kick all the way back. I am really hoping there is a common failure I can look for.
