So my new to me 04 Sequoia had some codes.
Two evap codes but I found a loose/cracked hose in the engine and that seemed to fix that.
The tailpipe had rusted off the muffler outlet. Last night I reconnected it with a piece of tailpipe and clamps.
Today I popped the P0420 code, "Catalyst System Efficiency Below Threshold Bank 1.
I set up my TorquePro app to monitor the O2 voltages.
I thought if the Cat was bad the O2 would reflect it?
150418


And Bank 2.
150419


Any help would be appreciated.
