DTC P2009: Intake Manifold Runner Control Circuit Low (Bank 1); DTC P2010: Intake Manifold Runner Control Circuit High (Bank 1): Description

The ECM activates the DC motor for the intake air control valve actuator (for TCV), which opens and closes the Tumble Control Valve (TCV). The ECM activates the DC motor based on engine speed, coolant temperature, intake air temperature and other conditions.

DTC No. DTC Detection Condition Trouble Area
P2009 Both of the following conditions continue for 1 second (1 trip detection logic):
(a) The output duty of the DC motor for the intake air control valve actuator is 34% or higher.
(b) The current of the DC motor for the intake air control valve actuator is below 0.35 A.
