DTC Descriptor

DTC P2014 00: Intake Manifold Runner Control Valve Position Not Learned

The engine control module (ECM) performs the intake manifold runner procedure automatically when the enabling criteria have been met. After each ignition cycle, and before the enable criteria have been met, the ECM will use the previously learned value. If the ECM does not have a previously learned value, it will default to a stored calibrated value.

Conditions for Running the DTC

•	The battery voltage is equal to or greater than 11 V.

•	The engine speed is between 750-850 RPM.

•	The engine coolant temperature (ECT) is between 73-96°C (163-205°F).

Conditions for Setting the DTC

The engine control module (ECM) determines that the intake manifold runner position is not learned.

Action Taken When the DTC Sets

DTC P2014 is a Type C DTC.

Conditions for Clearing the DTC

DTC P2014 is a Type C DTC.

Diagnostic Aids

If any service has been performed on the intake manifold runner, a relearn must be performed.
