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 Swirl Control Valve (SCV), which opens and closes SCV. The ECM activates the DC motor based on engine rpm, coolant temperature, engine load signals and other conditions. When the voltage of the DC motor deviates from the standard range, the ECM determines that a malfunction has occurred and outputs a DTC.

DTC No. DTC Detection Condition Trouble Area
P2009 Both of the following conditions continue for 0.5 seconds (1 trip detection logic):
(a) The output duty of the intake air control valve actuator for swirl control valve is 100%.
(b) The current of the intake air control valve actuator for swirl control valve is below 0.35 A.
  • Open or short in DC motor for SCV circuit
  • Intake manifold (DC motor for SCV)
  • ECM
P2010 Either of the following conditions occurs for 6 times or more (1 trip detection logic):
(a) The motor drive IC is overcurrent.
(b) The motor drive IC overheats.
