Azera(TG) Engine Dragging and Cut Off After 3 min. Running

Model: Azera (TG)	Year model:2009	mileage:5o231km
Displacement:2700cc	Fuel: Gasoline	T/A: Auto

Subject: Engine Dragging and Cut Off After 3 min. running

1) Trouble Condition:

• Engine Dragging and Cut Off After 3 min. running.
• Engine No power on Acceleration.

2) Trouble Cause:

1. Engine Dragging and Cut Off After 3 min. Running,
   = CKP(Crankshaft Position Sensor)
   = OCV(Oil Control Valve)

3) Diagnosis:

1. Scan Tool Check
   = Trouble Code: P0016 – Cranckshaft and  camshaft correlation.
2. Check the Current Data of CKP = Out of Specification= Replace w/ New
   = the Engine now Have power on acceleration but still Cut off occurred.

GENERAL DISCRIPTION
= According to the General Description of this Trouble code,The CVVT(Continuously Variable Valve Timing). This system Controls the intake camshaft to provide the optimal valve timing for every driving condition. The ECM(Engine Control Unit) controls the OCV, based on the signal output from the mass air flow, Throttle Position and engine coolant temperature. The CVVT controller regulates the intake camshaft angle using oil pressure through the OCV. As a result , the relative position between crankshaft and camshaft become optimal, and the engine torque improves, fuel economy improves, exhaust emissions decrease under overall driving conditions.

= Try a good condition OCV, As a result the Engine operates normally. 

4) Repair Guide:

Replace Parts:

1. CKP(Crankshaft Position Sensor)
2. OCV(Oil Control Valve)
