DTC P2070 IMT - keywords intake manifold tuning valve

This PI was updated to clarify wording. Please discard PIP3902.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

2007 Saturn Aura with LY7 3.6L V6 engine. Some customers may comment of a check engine light with DTC P2070 stored. The cause may be excess Loctite on the bushing for the intake manifold tuning valve causing the valve to stick.

Call TAC and set up a case to record identifying paint marks. These marks will be located on the IMT valve and on the intake. Record the color and location in the TAC case. If routine diagnosis using SI indicates a fault in the intake manifold tuning valve, remove the valve and check for Loctite on the end of the valve shaft. If Loctite is present, remove it using emery cloth, reinstall the valve, and check for proper operation.

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.
