CAUTION / NOTICE / HINT

Tech Tips

Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. 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

CHECK FOR ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0016 OR P0018)

Connect the GTS to the DLC3.
Turn the engine switch on (IG) and turn the GTS on.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

Read the DTCs.

PERFORM ACTIVE TEST USING GTS (OPERATE OCV)

Connect the GTS to the DLC3.
Start the engine and turn the GTS on.
Warm up the engine.
Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT System (Bank 1) or Control the VVT System (Bank 2).

Check the engine speed while operating the camshaft timing oil control valve assembly using the GTS.

GTS Operation	Specified Condition
OCV OFF	Normal engine speed
OCV ON	Engine idles roughly or stalls soon after camshaft timing oil control valve assembly switched from off to on
