A quick scan shows the same issues, but is now reported on the Exhaust cam sensor 2 (when it was intake sensor last time). This tells me that either the task of replacing the intake sensor knocked or damaged the exhaust sensor, or it has also failed but was being masked by the intake sensor, or it’s decided to fail out of pure coincidence, or there’s something else going on.

Oh well, back to the tech I go... Doh!
Honestly to me it sounds like you have a short in wire harness, metals expand and retract due to heat so you could have a section of wire that is bad. It's just odd that two sensors quit like that. Are they both on the same bank of the engine?
