POSSIBLE CAUSE

Harness or connectors (Intake manifold runner control position sensor circuit is shorted.)
Intake manifold runner control position sensor

FAIL-SAFE

Engine operating condition in fail-safe mode
Fail safe mode		Vehicle behavior
Device fix mode		This mode fixes the EVT control solenoid valve in the reference position. The intake manifold runner control valve motor is turned OFF (intake manifold runner control valve opens).

DTC CONFIRMATION PROCEDURE

CHECK DTC PRIORITY
If DTC P2014, P2016, P2017 or P2018 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643.
