DTC P0010-00: Electric Variable Valve Timing Control Circuit Range/Performance Problem: Notes

DTC P0010:00 (PCM, SKYACTIV-G 2.5T) DETECTION CONDITION AND POSSIBLE CAUSE

DTC P0010:00 Electric variable valve timing control circuit range/performance problem
DETECTION CONDITION
  • Any one of the following conditions is met:
    • A malfunction is detected in the results of the on-board diagnostic test received from the electric variable valve timing driver.
    • The motor speed signal received from the electric variable valve timing driver is in error.

    Diagnostic support note 

  • This is a continuous monitor (CCM).
  • The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
  • FREEZE FRAME DATA/Snapshot data is available.
  • DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION
  • Stops activation of the electric variable valve timing driver.
POSSIBLE CAUSE
  • Electric variable valve timing motor/driver connectors or terminals malfunction
  • Electric variable valve timing relay malfunction
  • Short to ground or open circuit in electric variable valve timing relay power supply circuit
