Sprinkler station question

I have a system that came with the house we just purchased and I have a question regarding the zones...the controller is a Rainbird ESP-Modular, with expandable modules...9 zones are installed and programmed in the the controller, however, only 8 are operating, 9 does nothing. I can only locate 3 valve boxes in the yard so far, unless one is grown over. Anyway, my question is, I should have 9 valves since I have 9 stations, correct? Now if I open each valve box and count a total of 9 valves total from all 3, then I can assume station 9 is dead...anything less than 9 valves then I need to look for another valve box? I did get 26 volts on station 9 at the controller when I did a manual run on it, but no action anywhere in the yard. I should add that the whole yard is covered by stations 1 thru 8 except a strip on the other side of my driveway, I think this could be station 9. The wire is pink on the controller for station 9. Common sense would tell me to look for a pink wire in one of the valve boxes and take a voltage reading at that point. Do all valves come with a manual control to activate them at the valve itself for testing? I am thinking that if station 9 did not ever exist, why wire it up to the controller. Thank you!

If there was a valve connected to station 9, you could detect it by resistance measuring.

I checked my yard this weekend, can only find 3 valve boxes containing a total of 6 valves, I have 8 operating stations, so I need to locate the other box or boxes. I am guessing they are buried in the flowerbeds or something.

I need to add that if the wire colors at the controller are the same wire colors at the valves, then I haven't located the 9th valve yet, it is pink and none of the valve boxes I've opened have a pink wired valve. The search continues......

OK, I used a copper 4 foot grounding rod I had to probe the part of the yard where the valves should be located, close to the stations they operate, I got lucky, I found two valve boxes side by side buried under some dirt and grass. Haven't opened them yet, but one should have two valves in it, the other just one. So I will manually open the valve for station 9 and see if it operates and if so, troubleshoot the valve and wiring. Hopefully it is just a bad solenoid.

Manually tested the valves inside the boxes I found, found station 9, it runs where I thought it should down the driveway and actually had a couple of extra heads located where I didn't expect any. I need to voltage check and if need resistance troubleshoot that valve and get it going.
