Hey Guys,

so getting the car back together and I am getting these codes and thus I can not start the car. I am almost certain that it is a grounding or short issue. I just can not seem to find it. I have cleaned all the grounds but this has changed nothing.

P0123- throttle position sensor/ switch A circuit high input
P0223- throttle position sensor/ switch B circuit high input
P0118- coolant temp circuit high input
P0244- wastegate control solenoid valve malfunction

any help on this would be great.

Wiring diagram shows TPS/ECT/MAP share same ground and goes through a patch harness before the ground tabs. Is the MAP reading out of wack as well (key on engine off)?
