I love your posts, Scotty!  I've been watching your posts for many years.

My car is an Automatic Transmission 2005 Toyota RAV4 with 212,598 miles.  Codes are P0442 and P0456.

My RAV4 has an engine check light that several technicians have been unable to fix.  I've spent THOU$ANDS on this problem due to unscrupulous technicians.  My present technician, who I also love, cannot figure this problem out either.  My present technician is an ASE Certified company in my new local area down near Galveston.  Moreover, I trust these techs because they simply cannot find the problem, and instead of just "flipping the switch" to kill the light for about 59 1/2 miles, they just told me they cannot find a fix for this problem.

Thanks Mr. Car Killer — Scotty!
