Hello my name is ***** ***** I will be helping you today. There is a common issue with the IMTV bushing inside the intake shifting not being there. Here is the text from the GM publication.

"Condition/Concern:
Some owners may comment that the Service Engine Soon (SES) light is on. Using a Tech 2 you may find that there is DTC P2070 or P2071 or P2077 or P2078 stored in the Powertrain Control Module (PCM).

The bushing located inside the upper intake manifold that supports the tip of the intake manifold tuning valve shaft may be missing.

Recommendation/Instructions:
Remove the intake manifold tuning valve and inspect the inside of the upper intake manifold to see if the bushing is present.

If the bushing is NOT present then the upper intake manifold and intake manifold tuning valve will have to be replaced. Refer to the appropriate section in SI for replacement procedures. ·If the bushing IS present then proceed with your diagnosis of the intake manifold tuning valve.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed."

Please remember to rate my service and accept the answer! This does not end our conversation and I will continue to assist with any further questions that you may have. If needed I am available for a premium phone for added convenience.

Still researching on that one. Give me just a few more minutes.

Can you back probe the connector on Bank 1 and provide me the voltage? Also ensure the connector is problem plugged in.
