Hello all,

I was looking for some help. I recently had to do a motor swap in my wifes 2011 Acadia Denali AWD. Everything went fairly well and when it was swapped I had no errors and I thought I was in the clear. I had it running off and on at Idle for over an hour as I was purging the coolant lines and just making sure everything was ok. But after taking it for a test drive I got the following codes:
P2090
p0013
P2094
P0023
P2088
P0010
P0020
P0031
p0051
P0123
P0154
P0458
I have checked I have voltage at at least one if the solenoids so I do think it'* a power problem. I tried to communicate with it with my scanner and all I get for values is 0 for all of the VVT solenoids so there is something not right. Has anybody every seen this? Any ideas on what I can try?

TIA,
Confused.

Sorry....should have read I don't think it'* a power issue.

I hardly ever hear of engine swaps in these.

What was the problem with the original engine?

Were there any codes stored before the swap?

How many miles on the car?

How many miles on the replacement engine?

Year/make/model of the donor car that the replacement engine came from?

Did the PCM come with the replacement engine or are you using the PCM that was originally in your car?

What were the circumstances of the donor vehicle'* demise?

Did you do this swap yourself or have help or have it done in a shop?

Regarding the codes:

P2090 - B Camshaft Position Actuator Control Circuit Low Bank 1

p0013 - B Camshaft Position Actuator Circuit (Bank 1)

P2094 - B Camshaft Position Actuator Control Circuit Low Bank 2

P0023 - B Camshaft Position Actuator Circuit (Bank 2)

P2088 - A Camshaft Position Actuator Control Circuit Low Bank 1

P0010 - A Camshaft Position Actuator Circuit (Bank 1)

P0020 - B Camshaft Position Actuator Circuit (Bank 2)

P0031 - Oxygen (A/F) Sensor Heater Control Circuit Low (Bank 1 Sensor 1)

P0051 - Oxygen (A/F) Sensor Heater Control Circuit Low (Bank 2 Sensor 1)

P0123 - Throttle Position Sensor/Switch A Circuit High Input

P0154 - 02 Sensor No Activity Circuit B2S1

P0458 - EVAP Emission System Purge Control Valve Circuit Low

Overall, based on the list above, I'd suspect some stuff isn't plugged in and/or grounding between the body and engine is incomplete.

Double check your work.
