Toyota Avalon Knock Sensor Codes?

Asked by Oct 29, 2016 at 01:35 PM about the 2002 Toyota Avalon XLS

Question type: Maintenance & Repair

I've got a 2002 Avalon that recently started
losing power, and had a low growl when
under a load. It started after a minor
misfire. After replacing all six plugs and
coils the misfire went away, but the loss of
power got gradually worse until the car will
barely accelerate at all, and at 2300 RPM's
it starts bucking, like the computer is
limiting the RPM's. Codes for Knock
Sensor in bank 1 and 2, I ended up
replacing the harness because I can't
afford the sensors themselves. My
question is this: are the sensors the likely
issue? I can't start it to find out if it fixed
the problem because my fuel pump
stopped working, which leads me to my
next question: is there a connector
somewhere that would've had to be
removed to take the upper and lower
plenum off (on a 1MZ-FE) that, if not
reconnected, would prevent the fuel pump
from operating?
