These codes were up and I cleared them trying to reset stuff on the side of interstate 57, the 02 is always there but the lean after going through water and changing plugs and drying upper plenum, it triggers the vtm code of powertrain failure. The p1456 code and the cmp sensor and misfire happened on 57

I would say replace the O2 sensors because this affects air/fuel mixture, but your note says your oil is milky? That is usually caused by coolant mixing in the oil.

If I may weigh in here, all these your present codes?

First check the timing belt and make the timing marks line up on the crank and both cams, the belt may have jumped a couple teeth. Pull the rubber caps on both plastic cam covers and you should see both marks with the crank timing mark lined up. If you don't see either mark with crank timing mark lined up rotate the engine 1 more time. If the marks aren't align then you timing belt jump, which is quite common on the rear (bank 1, cylinder 1) head.

Next check to make sure you good battery voltage >12.5 off and around 14 running. Make sure nothing is shorted out. Make sure any connectors that got wet are dry all the way through.

P0131 and P0132 both relate to the B1S1 (only) the non-heater side (circuit) is probably shorted. This the rear bank near the firewall, check to see you have signal from the harness and it's not burnt through somewhere.
P0340 and P0365 relate to the Camshaft sensor on bank 1 cylinder (rear) again the sensor or wiring fault.
P0170 and P0171 again point Bank 1 sensor 1 "upstream of the converter" reading "too lean" P0170 just mean the mixture is off it can be either lean or rich.
P01399 (misfire) can be from valve out of adjustment or an EGR leak which is most likely related to your P01456.

Where did you get the 2-1, 4-1, 9-3, and 119-1?

The 119-1 usually mean nothing (VTM related, meaning turned off) that results from other codes being set or poor power connections. VTM seems to get disconnected a lot on Pilots for any "hiccup". DTC 2-1 refers to the passenger air bag (open circuit resistance) part of SRS which can also trigger the 119-1. DTC 4-1 is open circuit in passenger belt tensioner or buckle, 9-3 means the same except for the driver's side. Try good power and reset the codes. You can test the grounds by DVOM having one lead on the disconnect negative battery lead and touch the other to the body ground points, you should have less than 5 ohms resistance and not reading O.L. on the DVOM. If there's more than 5 ohms there's most like corrosion in harness. If the DVOM reads O.L. (open loop) the circuit is broken. Hope this gives you a place to start as many of the codes are associated with bank 1 (the one near the firewall). Start with the timing marks. Attached are pictures of timing marks and look at the upper plastic cam covers to see the rubber inspection plugs.
