DTC P0017: Crankshaft/camshaft (exhaust) Position Sensor Phase Problem

TECHNICAL DESCRIPTION

• The ECM checks the variable valve timing system for malfunction.
  

DESCRIPTIONS OF MONITOR METHODS

The close timing of the exhaust valve is faster or slower than the specified value.

MONITOR EXECUTION

Continuous

MONITOR EXECUTION CONDITIONS (Other monitor and Sensor)

• Not applicable
  

• Camshaft position sensor
  
• Crankshaft position sensor
  
• Engine coolant temperature sensor
  
• Throttle position sensor
  
• Engine oil control valve
  

DTC SET CONDITIONS

• Engine speed is between 594 r/min and 1,500 r/min.
  
• Engine coolant temperature is between 20°C (68°F) and 88°C (190°F).
  
• Exhaust engine oil control valve is "OFF".
  
• 1 second has elapsed after the above mentions have been met.
  

• The close timing of the exhaust valve is faster than -7.7 degrees (ATDC) for 10 seconds.
  

• The close timing of the exhaust valve is slower than 5.4 degrees (ATDC) for 10 seconds.
  

FAIL-SAFE AND BACKUP FUNCTION

• None
  

OBD-II DRIVE CYCLE PATTERN

Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 20 .

TROUBLESHOOTING HINTS (The most likely causes for this code to be set are:)

• Exhaust engine oil control valve failed.
  
• Timing chain in out of place.
  
• Loose timing chain.
  
• Exhaust variable valve timing sprocket tooth coming off.
  
• ECM failed.
  

	Go to Step 3.

	Replace the exhaust engine oil control valve. Then go to Step 2.

	Initialize the learning value for the elongation of the timing chain. Refer to GROUP 00, Precautions Befor Service - Timing Chain Maintenance . Then go to Step 4.

	Replace the timing chain and the oil pump chain. Then initialize the learning value for the elongation of the timing chain. Refer to GROUP 00, Precautions Befor Service - Timing Chain Maintenance . Then go to Step 4.

	Repair it. Then go to Step 2.

	Then go to Step 2.

(1)Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 20 .

	Retry the troubleshooting.

	The inspection is complete.
