No. For the Catalyst Efficiency Monitor, the code is erased if the malfunction is not detected during three sequential driving cycles.
If you're only getting a cat efficiency code, I'd say pay them the $80 and see if they'll replace it. Besides, you could just be wasting that $80 by needlessly replacing the O2s first. I'd go with the repair that may be reimbursible first.

Does the computer store the code for future reference (presuming the battery stays connected) even if the CEL is turned off?
