Same issue just popped up for me - do you by chance have a picture of where these sensors are located on your engine block? Trying to diagnose the problem myself too...

Did you ever get a resolution to this? I have the same lights popping up on my dash. I had them before and I didn’t know what the problem was then my ignition coils went out so then I replaced them and the lights went away but after about 2 months they came back on. I hear a slight knock when I accelerate from zero but any other time I don’t hear it. Also my fuel economy is lower than usual.
