DTC P0011 (56): ADVANCED DIAGNOSTICS

DTC P0011: VARIABLE VALVE TIMING CONTROL (VTC) SYSTEM MALFUNCTION

Fig. 1: Identifying Variable Valve Timing Control (VTC) System Consisting Components With Flow
Diagram

General Description

The variable valve timing control (VTC) system controls the timing of the intake camshaft. It uses hydraulic
pressure to operate the VTC actuator so the valve timing is optimized depending on driving conditions. The
engine control module (ECM)/powertrain control module (PCM) monitors the phase control command and the
actual timing of the camshaft by using camshaft position (CMP) sensor A. If the phase difference between them
is excessive for a certain time period, a malfunction is detected and a DTC is stored.

1. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator

fan comes on.

2. Drive the vehicle at a steady speed between 25 - 75 mph (40 - 120 km/h) for at least 15 seconds.



Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.

Diagnosis Details

Conditions for illuminating the MIL

When a malfunction is detected during the first drive cycle, a Temporary DTC is stored in the ECM/PCM
memory. If the malfunction recurs during the next (second) drive cycle, the MIL comes on and the DTC and the
freeze frame data are stored.

Conditions for clearing the MIL

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic
runs.

The MIL, the DTC, the Temporary DTC, and the freeze frame data can be cleared by using the scan tool Clear
command or by disconnecting the battery.

Fig. 3: Actual Intake Airflow Versus Presumed Intake Airflow Graph

General Description

The mass airflow (MAF) sensor directly measures the amount of intake airflow into the engine, and the engine
control module (ECM)/powertrain control module (PCM) controls the fuel injection based on the measured
value. The manifold absolute pressure (MAP) sensor measures the intake manifold pressure and the ECM/PCM
calculates the amount of intake airflow from the MAP sensor output and the engine revolutions. The ECM/PCM
compares the MAF sensor output (amount of intake airflow) and the amount of intake airflow calculated from
MAP sensor output. If their difference is too large (in the malfunction area), the ECM/PCM detects a
malfunction and a DTC is stored.
