So based loosely on the discussion of disabling the EGR system altogether found in this thread http://forum.ih8mud.com/80-series-te...oyota-way.html
among others, I decided to experiment and have bypassed my faulty temp sensor. It's still installed, but I unplugged in then jumpered the wires in the harness, as if the sensor is "on" all the time now.
So far it's been 2 weeks and about 200 miles, and no CEL
. Also a lot of idling, including the SNR, highway driving, commuting, all the conditions that would have tripped it before. So no CEL means problem solved right?
