edit: for got to say reset the Errors first , then drive and see if they come back, it can take a fuel miles for some.... (pulling dome fuse, resets the ECU, errors) easy .
All ecu's runs catastrophic monitors (tests full time).
that find, dead open and dead shorted sensors. it never lies about this! )well, if you pull sensors with the key on, it will store those errors, how could it not?).
Most those errors.. cause:
This causes ECU to drop to limphome mode, Sucks gas like demon, (rich and retarded spark and rpm cap, and idle controls off line) a lil' horror that driving. flooding, black tipped spark plugs and that nasty black cloud stink and red hot CAT. and more....
0v is shorted (sensor line)
5v is dead open line. (cut line) ECU sees both FAST if true. it does this quite well and fast.
your ground wire is open
14= ECT disconnect < it has only 2 wires.
45= Idle switch in TPS failed. (it must ground at idle (0v) or fails this. or the ground to TPS is cut. can cause a double TPS failure,
53= EGRT sensor dead open.
21= TPS throttle angle pin , stuck high, for same reason all above the lost GROUND each of the above share.
the ground wires to each in a funny way,,, ( I cant predict that. as ive never unwrapped a whole harness end to end.. be pain that.
but is wire in odd way,, one of the 5 sensors ground has damage , the one with damage kills the other DOWN THE LINE.
it that simple.
my ECT drawing shows that.
from poster last week, same problem
YOUR GRAY-YELLOW wire is cut.

the full drawing is here (see that ground structure, that drawing is made to be pretty, the actual ground jump are different."order")

no side can run right with DTC errors, none.,
and your is the worst of the worst and only a simple cut wire,,,,,
if the ground breaks near ECU all 5 sensors go DEAD.... (they are all still good ) but the ECU cant SEE THEM.
