No luck
so. I put the original valve block back on. Threw the code immediately. Got another new one from Amazon. Put that on. Threw the code too. One interesting note. When I first put the new one on i didn’t mount it onto the chassis. Figured I’d test it wasn’t leaking first. Ran fine. Thought to myself. Hello. That must be it. Then I Mounted it. Buttoned up the plastic casing feeling pleased with myself and sure enough it threw the code as soon as I started it. Maybe I Shd just drive the thing with it hanging off under the car ? Any ideas ?

I would normally say the pressure sensor is then suspect, but valve blocks have the sensor therefore you have already swapped it a couple times. The ONLY thing that reads pressure is that sensor. I would observe pressure readings when operating and see what happens. Either you will get weird pressure readings, meaning the sensor wiring is bad, or the sensor readings will be fine and consistent with the error meaning you have a blockage, lines hooked up wrong or bad wiring to the center block that is causing the solenoid not to energize open. Dont forget, the center block has two connectors, one for the sensor and one to operate the center block.
