CAUTION:
After servicing or replacing faulty parts, perform Clear Memory Mode Clear Memory Mode > OPERATION">
, and Inspection Mode Inspection Mode > PROCEDURE">.
| STEP | CHECK | YES | NO |
1.CHECK FOR ANY OTHER DTC ON DISPLAY.
Is DTC other than P0016, P0017, P0018 or P0019 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 P0017 CRANKSHAFT POSITION - CAMSHAFT POSITION CORRELATION BANK 1 SENSOR B">Go to Step 2.
2.CHECK EXHAUST OIL CONTROL SOLENOID RH.
Check the exhaust oil control solenoid RH. Oil Control Solenoid > INSPECTION">
Is the check result OK?
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0017 CRANKSHAFT POSITION - CAMSHAFT POSITION CORRELATION BANK 1 SENSOR B">Go to Step 3.
Replace the exhaust 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">
Is the timing chain installed in the proper position?
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0017 CRANKSHAFT POSITION - CAMSHAFT POSITION CORRELATION BANK 1 SENSOR B">Go to Step 4.
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 check result OK?
Replace the exhaust cam sprocket RH. Cam Sprocket"> After the operation is complete, go to the next step. Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0017 CRANKSHAFT POSITION - CAMSHAFT POSITION CORRELATION BANK 1 SENSOR B">Go to Step 5.
Replace the cam carrier filter. Cam Carrier">
5.CHECK CURRENT DATA.
1) Clear the memory using the Subaru Select Monitor or general scan tool. Clear Memory Mode > OPERATION">
2) Start the engine and warm up completely.
3) Using the Subaru Select Monitor, read the values of «VVT Ex Initial Position Learning Value #1» and «Exh. VVT Retard Ang. R» while the vehicle is in stable condition for 30 seconds or more with the engine idling.
NOTE:
For detailed operation procedures, refer to “Current Data Display For Engine”. Subaru Select Monitor">
4) Calculate the values using the following formula. Ignore the unit at this time.
|«VVT Ex Initial Position Learning Value #1» − (90 − «Exh. VVT Retard Ang. R»)|
Is the calculation result less than 10?
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0017 CRANKSHAFT POSITION - CAMSHAFT POSITION CORRELATION BANK 1 SENSOR B">Go to Step 6.
Replace the ECM. Engine Control Module (ECM)">
6.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 exhaust 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 external load (power steering, neutral position switch) change | ≥ 3000 ms |
Exhaust AVCS position learning | In operation |
3. GENERAL DRIVING CYCLE
Perform the diagnosis continuously while the exhaust AVCS is not operating after warming up.
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.
Malfunction Criteria | Threshold Value |
One tooth shifted | |
|Crankshaft position when camshaft position sensor signal is input − Learning value| | > 10 °CA |
Two teeth shifted | |
Camshaft position sensor signal input position (Bank 1) | < 63.9 °CA or > 121.64 °CA |
Camshaft position sensor signal input position (Bank 2) | < 62.11 °CA or > 120.79 °CA |
