Subaru Legacy BN/BS (2015-2019) Service Manual / Engine (diagnostics)(h4do) / Diagnostic procedure with diagnostic trouble code (dtc) / Dtc p0016 crankshaft position - camshaft position correlation bank 1 sensor a

DTC DETECTING CONDITION:

Detected when two consecutive driving cycles with fault occur.

TROUBLE SYMPTOM:

• Engine stalls.

• Improper idling

CAUTION:

After servicing or replacing faulty parts, perform Clear Memory Mode Clear Memory Mode > OPERATION, and Inspection Mode Inspection Mode > PROCEDURE.

STEP

CHECK

YES

1.CHECK FOR ANY OTHER DTC ON DISPLAY.

Is DTC other than P0016 and P0018 displayed-

Check the appropriate DTC using the “List of Diagnostic Trouble Code (DTC)”. List of Diagnostic Trouble Code (DTC)

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0016 CRANKSHAFT POSITION - CAMSHAFT POSITION CORRELATION BANK 1 SENSOR A

2.CHECK INTAKE OIL CONTROL SOLENOID RH.

Check the intake oil control solenoid RH. Oil Control Solenoid > INSPECTION

Is the intake oil control solenoid RH normal-

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0016 CRANKSHAFT POSITION - CAMSHAFT POSITION CORRELATION BANK 1 SENSOR A

Replace the intake oil control solenoid RH. Oil Control Solenoid

3.CHECK INSTALLATION CONDITION OF TIMING CHAIN.

Using ST and by turning the crankshaft, align the alignment marks of crank sprocket, intake cam sprocket and exhaust cam sprocket. Timing Chain Assembly

ST 18252AA000

CRANKSHAFT SOCKET

Is the timing chain installed in the proper position-

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0016 CRANKSHAFT POSITION - CAMSHAFT POSITION CORRELATION BANK 1 SENSOR A

Correct the installation condition of timing chain. Timing Chain Assembly

4.CHECK CAM CARRIER FILTER.

Check the filter installed to the cam carrier. Cam Carrier > INSPECTION

Is the cam carrier filter normal-

Replace the intake cam sprocket RH. Cam Sprocket After the operation is complete, go to the next step. Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0016 CRANKSHAFT POSITION - CAMSHAFT POSITION CORRELATION BANK 1 SENSOR A

Replace the cam carrier filter. Cam Carrier

5.CHECK DTC.

1) Clear the memory using the Subaru Select Monitor or general scan tool. Clear Memory Mode > OPERATION

2) Perform drive cycle N. Drive Cycle > PROCEDURE

Is the same DTC as current diagnosis output-

Replace the ECM. Engine Control Module (ECM)

End.

1. OUTLINE OF DIAGNOSIS

Detect the AVCS system malfunction.

Judge as NG when standard timing advance amount is far from learning angle.

2. EXECUTION CONDITION

Secondary Parameters	Execution condition
Battery voltage	≥ 10.9 V
Elapsed time after the neutral position switch changed	≥ 3000 ms
AVCS learning	In operation

3. GENERAL DRIVING CYCLE

Perform the diagnosis continuously after starting engine and while AVCS is not operating.

4. DIAGNOSTIC METHOD

Judge as NG when the absolute value of the difference between cam signal input position and learning value is out of specification.

Diagnosis 1

If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.

Judgment Value

Malfunction Criteria	Threshold Value
\|Crankshaft position when camshaft position sensor signal is input − Learning value\|	> 10 °CA

Time Needed for Diagnosis: 5000 ms

Diagnosis 2

Judgment Value

Malfunction Criteria

Threshold Value

Camshaft position sensor signal input position

< −2.119 °CA

> 61.77 °CA

Time Needed for Diagnosis: 5000 ms

Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.

NOTE:

Initial standard learning value is the value of crank angle initially input at the production plant. And then it will be updated every time normal judgment has been completed. Learning value will not be updated if NG judgment occurs because timing belt or chain derails suddenly in process or because wrong assembly occurs during servicing.
