If the deviation between CKPS and CMPS is bigger than the threshold value, the ECM/PCM sets DTC P0016.
Item | Detecting Condition | Possible Cause | |
DTC Strategy | Case1 |
•
Intake camshaft edge in VVT Full Retard position out of Range compared to Reference position | 1. Poor connection 2. Contamination of Oil / Clog of Oil path 3. CKPS, CMPS 4. OCV 5. CVVT |
Case2 |
•
Alignment between the camshaft and crankshaft is off by one or more cam/crank sprocket cogs | ||
Enable Conditions | Case1 |
•
Intake CAM adaptation value vali (16 CAM edges with VVT in Full Retard) irst active signal edge -> camshaft segment period determination -> camshaft ratio determination -> camshaft synchronization -> cam edge counter > 16 | |
Case2 |
•
Time elapsed after Intake camshaft > 2sec
•
Engine synchronized
•
Intake camshaft signal present Intake VVT system equipped | ||
Threshold Value | Case1 |
•
Intake Camshaft position adaptation < -15°CRK or > 15°CRK | |
Case2 |
•
Camshaft edge position jump > 10°CRK | ||
Diagnostic Time | Case1 |
•
80 revs | |
Case2 |
•
35 revs | ||
MIL ON Condition | Case1 |
•
