5		No	Go to the next step
6	INSPECT ROTOR POSITION Remove the variable valve timing actuator. (See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION [L5] .) Is the rotor at the maximum valve timing advanced position?	Yes	Reinstall or replace the variable valve timing actuator, then go to the next step. (See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION [L5] .)
6		No	VARIABLE VALVE TIMING MECHANISM IS NORMAL NOTE: This DTC is detected as an intermittent concern. An intermittent concern might be removed using the cleaning mode of the variable valve timing control function. Go to the next step.
7	VERIFY DTC TROUBLESHOOTING COMPLETED Make sure to reconnect all disconnected connectors. Clear the DTC from the PCM memory using the M-MDS. Switch the ignition to off.
