Yes...a leaking exhaust system (before or in between the cats) can cause
this. Could also be the cat - looking at your mileage.

Subject: DML: P0433 Heated Catalyst Efficiency Below Threshold (Bank 2)
Any body ever have a P0433 code? I searched the forums and a quick
Google search, but it doesn't seem to be very common.
The truck is a 2000 QC 4.7L 5spd with 184,000 km (~110,000 miles).
Dealer reported recently that I have a broken exhaust manifold stud.
Could that be related to this code?
Thanks in advance for any help.
Rob S.
