This is concerning my 2001 Camry 4cyl auto with 215k miles and has been maintained very well.
I have the dreaded p0420 and replaced the exhaust manifold/front cat with toyota oem. Code went away for 300 miles then came back.
Original toyota O2 sensors on the car. I have a scanner and have the following freeze frame info.
Trouble Code ....P0420
Engine Speed ...1492 rpm
Calc Load ........47.8%
MAP ...............48 kpa
Coolant ...........185 degrees
IAT ................118 degrees

This is my daughters car and I have been longterm unemployed. I want to pinpoint this as best as possible.
Thanks in advance
