Monitor Description
WARNING: This page is about a different variant/trim than selected.
The ECM monitors the continuously variable valve lift controller assembly and detects malfunctions. If the actual duration differs from the requested duration by 14.5°CA or higher, the ECM illuminates the MIL and stores a DTC. DTC P10A0 is usually only stored if a malfunction is detected during cold engine start. DTC P1055 is stored if a malfunction is detected in any other situation.
