Repair Procedure

1. Using Techstream, review the Freeze Frame Data for DTC P0335.

Does the FFD indicate the engine was at operating temperature and near idle speed when the DTC was stored?

HINT

^ Coolant Temperature is approximately 185°F (85°C) or more.

^ Engine RPM is less than 1000 RPM.

YES- Proceed to step 2.

NO - This bulletin does NOT apply





Refer to the Technical Information System (TIS), applicable model and model year Repair Manual.





2. Remove and replace the camshaft timing gear assembly. Refer to TIS, applicable model and model year Repair Manual.





3. Identify whether the camshaft timing gear is unlocked or locked. (See Figure 1).

^ If the camshaft timing gear is unlocked, it is ready to install.

^ If it is LOCKED, follow the steps below to unlock the camshaft timing gear before installing.

A. To disengage the camshaft timing gear lock pin, apply and hold approximately 21 psi of air pressure at the oil feed hole located 90 degrees clockwise of the oval slot.





B. With the 21 psi of air still applied to the gear, turn the interior assembly counterclockwise. (See black arrow in Figure 2.)





C. Install the timing gear assembly onto the camshaft with the straight pin slightly to the right of the key groove as shown.

D. Turn the camshaft timing gear assembly while pushing it lightly against the camshaft until the straight pin engages the key slot.





E. Check that the camshaft timing gear is fully seated on the camshaft and that there is no clearance between the end of the camshaft and the timing gear. Install the camshaft bolt finger tight.

F. While holding the camshaft with a wrench, torque the camshaft bolt.

Torque: 54 N*m (551 kgf*cm, 40 ft*lbf)

G. After torquing the camshaft bolt, rotate the camshaft timing gear clockwise while holding the camshaft stationary until the dots are aligned, to engage the camshaft timing gear lock pin.

H. Install the timing chain.

4. Clear DTCs using Techstream.

5. Test drive the vehicle to confirm the repair.
