DESCRIPTION
The Variable Valve Timing (VVT) system adjusts the exhaust valve timing to improve driveability. The engine oil pressure turns the VVT controller (camshaft timing exhaust gear assembly) to adjust the valve timing.
The cam timing oil control solenoid assembly (for exhaust camshaft) operates according to signals received from the ECM to control the position of the camshaft timing oil control valve assembly (exhaust camshaft timing gear bolt assembly) and supply engine oil. The camshaft timing oil control valve assembly (exhaust camshaft timing gear bolt assembly) moves when the ECM applies 12 V to the cam timing oil control solenoid assembly (for exhaust camshaft). The ECM changes the energizing time of the cam timing oil control solenoid assembly (for exhaust camshaft) duty-cycle in accordance with the camshaft position, crankshaft position, throttle position, etc.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Note |
---|---|---|---|---|---|
P001313 | Camshaft Position "B" - Actuator Bank 1 Circuit Open | Open or short in cam timing oil control solenoid assembly (for exhaust camshaft) circuit (1 trip detection logic). |
| Comes on | SAE: P0013 |
MONITOR DESCRIPTION
These DTCs are designed to detect an open or short in the cam timing oil control solenoid assembly (for exhaust camshaft) circuit. If the cam timing oil control solenoid assembly (for exhaust camshaft) duty-cycle is excessively high or low while the ignition switch is ON or the engine is running, the ECM will illuminate the MIL and store this DTC.

HINT:
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
1. | CLEAR DTC |
(a) Record the Freeze Frame Data.
Powertrain > Engine > Trouble Codes(b) Clear the DTCs.
Powertrain > Engine > Clear DTCs(c) Turn the ignition switch off and wait for at least 30 seconds.
|
2. | READ OUTPUT DTC (DTC P001313) |
(a) Start the engine.
(b) Read the DTCs.
Powertrain > Engine > Trouble Codes Result | Proceed to |

4. | CHECK HARNESS AND CONNECTOR (CAM TIMING OIL CONTROL SOLENOID ASSEMBLY (FOR EXHAUST CAMSHAFT) - ECM) |
(a) Disconnect the cam timing oil control solenoid assembly (for exhaust camshaft) connector.
(b) Disconnect the ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
D17-1(+) - D104-25(OE1+) | Always | Below 1 Ω |
D17-2(-) - D104-26(OE1-) | Always | Below 1 Ω |
D17-1(+) or D104-25(OE1+) - Body ground and other terminals | Always | 10 kΩ or higher |
D17-2(-) or D104-26(OE1-) - Body ground and other terminals | Always | 10 kΩ or higher |
OK | REPLACE ECM |
NG | REPAIR OR REPLACE HARNESS OR CONNECTOR |
WARNING
When removing the fuel-filler cap, loosen the cap slightly and wait for any hissing to stop, then remove it
Fuel spray is dangerous. Fuel can burn skin and eyes and cause illness if ingested. Fuel spray is released when there is pressure in the fuel tank and the fuel-filler cap is removed too quickly.
