Hello, I have a 2007 Honda Odyssey EX. Recently got a flashing D light and a check engine code. Code reads P0843 transmission fluid pressure sensor/ switch a circuit high. Fluid is good and at normal level. I’ve enclosed a screen shot of the transmission that I got from Honda Parts. It looks like there are three pressure switches. Looks like two of them are the same (#11) and are located at the top and towards the side. The other is different (#12) is located at the bottom. I am trying to figure out which one of these switches is setting the code. And how do I test the switch? All I’ve been able to gather is that 5 volts goes to each of them, but I am not sure that’s accurate. Any help would be appreciated. Thanks.
