Multiple codes after srandpipe ipr replacement
Got my 06 back together after replacing standpipes and ipr. Slow to start but did start and idle. Zero throttle response. Check engine light and wrench light were on. I did find a ground I missed that comes out of the FICM harness and attaches to the intake heat shield bolt. Got it reattached but still have numerous codes. I will try to post a Pic of the codes but I seem to have trouble with that. The codes are listed below. codes were read with forscan. All have open circuit short to ground type descriptions. I'm thinking I missed a plug or a ground connection. Got everything tore apart again and absolutely can't find it. Any help would be greatly appreciated.

Did you check the ground that attaches to the rear driver side intake manifold bolt?
Did you triple check the FICM plugs?
Could be that simply moving an old harness that's been in the same position for years caused a wire housing to crack or break.

You have 3 codes that have the EBP sensor (or a wiring short) directly in common. The rest are also 'related", but more indirectly so.
The simplest check is to disconnect the EBP sensor and see if the engine operation improves (inspect the connector). You might have a short in the EBP wiring also. The most common place for a harness short that throws these codes is under the air intake tube (between the air filter and the turbo). A harness short in this location, or even an EBP sensor short can result in Throttle Position Sensor codes.
The last code is for the ICP sensor. It can be from a short, a bad sensor, or for trying to start with it unplugged. Inspect it!
What is in common w/ all these is the "signal return" circuit 359, gray wire with red stripe. And also the v-reference circuit 351, brown wire with white stripe.
There are several other chafe points to check that can result in essentially the same codes and engine performance. The ones mentioned above are the most common.
EDIT, for future readers

yes the ground on the intake manifold has been checked. Will look at FICM plugs

Fingers crossed
I don't know if the Pic uploaded. The pigtail for the ICP sensor was severely jacked up. Not corroded, not broken or cracked. Just a disaster of butt connections on bare wire. Not just a little bit but a couple inches at least. Poorly taped and twisted together. Once that problem was corrected all the others went away. Codes cleared went for a drive all appears to be as it should be.

Someone tell me if I'm wrong, but my recollection is that the ICP pigtail is 3-wire. So probably there was a short in the 5V V_REF and it caused a gremlin.

V-reference or signal return. I posted the circuit numbers (and wire colors) involved (mentioned ICP and EBP) in post #4.
Later I added a list of chafe points because they can result in the same behavior and codes.
