The sensor wires, if not relieved, can begin to crack as the exit the housing. I've also seen bad spark plug wires / connections cause this due to the EMI noise. Also from alternator regulators going out. Bad engine ground braids giving up. Did you recently service any of the mentioned items?
Just came out of annual so plenty of areas to check.
