Code No. P0016: Crank Angle Sensor/Camshaft Position Sensor Phase Problem

OPERATION

Refer to Code No. P0335: Crank Angle Sensor System
Refer to Code No. P0340: Camshaft Position Sensor System

FUNCTION

The engine-ECU monitors the signals input from the crank angle sensor and camshaft position sensor.
The engine-ECU compares these input pulse signals to check the position relations for validity.

TROUBLE JUDGMENT

Check Condition

Battery positive voltage is 8 - 16 V
One of the following two is true.

2 seconds have passed after the ignition switch is turned on, the crank angle sensor and camshaft position sensor output signals are normal, and the engine rotation speed is 1,200 r/min or lower.
Cranking is in progress, the engine rotation speed is 350 r/min or faster, and the engine cooling water temperature is -30°C or higher.

Judgment Criterion

The phase shift angle between the crank angle sensor and camshaft position sensor signals exceeds its threshold value.

PROBABLE CAUSES

Failed crank angle sensor
Failed camshaft position sensor
Failed timing chain
Failed engine-ECU

DIAGNOSTIC PROCEDURE

STEP 1. M.U.T.-III diagnosis code.

Q. Is any other diagnosis code than P0016 output?

	Inspection chart for diagnosis codes (Refer to ).

	Go to Step 2.

STEP 2. Check the timing chain.

See the timing marks to check for skipped gear teeth.

Q. Is the check result normal?

	Go to Step 3.

	Repair.

STEP 3. Check crankshaft sensing blade.

Q. Is the check result normal?

	Go to Step 4.

	Replace the crankshaft sprocket.

STEP 4. Check camshaft sensing vane.

Q. Is the check result normal?

	Go to Step 5.

	Replace the camshaft.

STEP 5. M.U.T.-III diagnosis code.

After clearing the diagnosis code through M.U.T.-III, start the engine and confirm whether the diagnosis code is set.

Q. Is the diagnosis code set?

	Replace the engine-ECU. When the engine-ECU is replaced, write the chassis number (Refer to GROUP 00 - Precautions Before Service - How to Perform Chassis Number Writing ). After replacing the engine-ECU, register the injector identification code and learn fuel injection (Refer to GROUP 00 - Precautions Before Service - What The Common Rail Engine Learns ).

	Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
