EC-156
DTC P0011, P0021 IVT CONTROL
Revision: 2006 November2007 350Z
DTC P0011, P0021 IVT CONTROLPFP:23796
DescriptionNBS00045
SYSTEM DESCRIPTION
*: This signal is sent to the ECM through CAN Communication line
This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake
valve.
The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant
temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing control solenoid
valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to
increase engine torque in low/mid speed range and output in high-speed range.

DescriptionNBS0004C
SYSTEM DESCRIPTION
*: This signal is sent to the ECM through CAN Communication line
This mechanism magnetically controls cam phases continuously with the fixed operating angle of the exhaust
valve.
The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant
temperature. Then, the ECM sends ON/OFF pulse duty signals to the exhaust valve timing control magnet
retarder depending on driving status. This makes it possible to control the shut/open timing of the exhaust
valve to increase engine torque and output in a range of high engine speed.
