DTC Advanced Diagnostics: P0013
DTC P0013:Variable Valve Timing Control (VTC) Oil Control Solenoid Valve B Malfunction

General Description

The variable valve timing control (VTC) system consists of the VTC actuator B, the VTC oil control solenoid valve B, various sensors, and the powertrain control module (PCM). The PCM controls the VTC oil control solenoid valve B by duty cycle and supplies hydraulic pressure to the advance chamber or the retard chamber in the actuator so the valve timing is optimized depending on the driving conditions (engine load, engine speed, and vehicle speed). If the difference between the VTC oil control solenoid valve B commanded current and the actual current is a specified current for a specified time, the PCM detects a malfunction and stores a DTC.

Malfunction Threshold
The difference between the VTC oil control solenoid valve B commanded current and the actual current is more than 0.20 A for at least 5 seconds.

Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
VTC oil control solenoid valve B VTC EX line short to ground
VTC oil control solenoid valve B VTC EX line open
VTC oil control solenoid valve B failure
PCM internal circuit failure

Confirmation Procedure
Operating Condition
1.
Start the engine. Hold the engine speed [ENGINE SPEED] at 3,000 rpm without load (CVT in P or N, M/T in neutral) until the radiator fan comes on, then let it idle.
2.
Drive the vehicle at a steady speed between 25 - 75 mph (40 - 120 km/h) for at least 5 seconds.

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

[ ]: HDS Parameter

With the HDS
Select the VTC TEST in the INSPECTION MENU with the HDS, then select the EX-VTC.

Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory.

Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the 12 volt battery.
