Default Code 16 (low res opti code)

What causes a code 16 (A low resolution pulse was not detected by ECM within 720 high resolution timing pulses)? If the Opti is for sure good what else would cause it? Seems to only happen at WOT.

I got this code when my opti died!!?? Check the connector at the opti and on the right side of the intake. Shoot a little contact cleaner in them. Good luck!
