| P0013 | Camshaft Position "B" Actuator Circuit / Open (Bank 1) |
| P0023 | Camshaft Position "B" Actuator Circuit / Open (Bank 2) |
DESCRIPTION
Refer to P000B Click here.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| P0013 | Oil control valve current is less than 0.306 A for exhaust camshaft circuit for 2 seconds or more (bank 1). (1 trip detection logic) |
|
| P0023 | Oil control valve current is less than 0.306 A for exhaust camshaft circuit for 2 seconds or more (bank 2). (1 trip detection logic) |
|
MONITOR DESCRIPTION
This DTC is designed to detect open or short in the camshaft timing oil control valve (for exhaust camshaft) circuit. If the camshaft timing oil control valve's duty-cycle is excessively high or low while the engine is running, the ECM will illuminate the MIL and store the DTC.
CONFIRMATION DRIVING PATTERN
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Clear DTCs (even if no DTCs are stored, perform the clear DTC operation) Click here.
Turn the ignition switch off and wait for at least 30 seconds.
Turn the ignition switch to ON and turn the GTS on.
Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher.
With the vehicle stationary, depress the accelerator pedal and maintain an engine speed of between 2500 and 3000 rpm for 40 seconds or more [A].
Drive the vehicle at 10 km/h (6.25 mph) or more for 1 minute or more [B].
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
Enter the following menus: Powertrain / Engine / Trouble Codes.
Read pending DTCs.
Tech Tips
If a pending DTC is output, the system is malfunctioning.
If a pending DTC is not output, perform the following procedure.
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
Input the DTC: P0013 or P0023.
Check the DTC judgment result.
| GTS Display | Description |
|---|---|
| NORMAL |
|
| ABNORMAL |
|
| INCOMPLETE |
|
| N/A |
|
Tech Tips
If the judgment result shows NORMAL, the system is normal.
If the judgment result shows ABNORMAL, the system has a malfunction.
If the test result is INCOMPLETE or N/A and no DTC is output, perform a universal trip and check for permanent DTCs Click here.
Tech Tips
If a permanent DTC is output, the system is malfunctioning.
If no permanent DTC is output, the system is normal.

CAUTION / NOTICE / HINT
Tech Tips
If DTC P0013 is displayed, check the exhaust camshaft circuit for the right bank VVT system (bank 1).
If DTC P0023 is displayed, check the exhaust camshaft circuit for the left bank VVT system (bank 2).
Bank 1 refers to the bank that includes the No. 1 cylinder*.
*: The No. 1 cylinder is the cylinder which is farthest from transmission.
Bank 2 refers to the bank that does not include the No. 1 cylinder.
Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
READ DTC OUTPUT
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Clear the DTC after recording the freeze frame data and DTC.
Turn the ignition switch off.
Start the engine and allow the engine to idle.
Enter the following menus: Powertrain / Engine / Trouble Codes.
Read DTCs.
