Page 1 of 7 DTC P0016 CRANKSHAFT POSITION-CAMSHAFT POSITION CORRELATION (BANK 1 SENSOR A) COMPONENT LOCATION 2008 Kia Sorento 3.3L Eng LX Fig 1: Identifying Crankshaft Position-Camshaft Position Correlation Sensor GENERAL DESCRIPTION The CVVT (Continuously Variable Valve Timing) system is installed to the chain sprocket of the intake camshaft. This system controls the intake camshaft to provide the optimal valve timing. The ECM controls the Oil Control Valve (OCV), based on the signals output from mass air flow, throttle position and engine coolant temperature. The CVVT controller regulates the intake camshaft angle using oil pressure through the OCV. As result, the relative position between the camshaft and the crankshaft becomes optimal, and the engine torque improves, fuel economy improves, exhaust emissions decrease under overall driving conditions. DTC DESCRIPTION ECM monitors timing misalignment while no active faults are present and fully warmed up engine oil at idle. If the timing is misaligned ECM determines that a fault exists and a DTC is stored. DTC DETECTING CONDITION DTC DETECTING CONDITION Item Detecting Condition Possible cause DTC Strategy Enable Conditions Determines if CAM target is aligned correctly to crank No active faults Fully warmed up at idle Loosened CKPS Timing Misalignment Threshold value Case 1 Case 2 1 teeth misalignment at 80 C (176 F) < Oil Temperature < 90 C (194 F) 2 tooth misalignment at Lower than 80 C (176 F) or Higher than 90 C (194 F)

Page 3 of 7 SIGNAL WAVEFORM AND DATA Fig 4: Signal Waveform And Data MONITOR DTC STATUS 1. Check DTC Status 1. Connect scan tool to Data Link Connector (DLC). 2. IG "ON". 3. Select "Diagnostic Trouble Codes (DTCs)" mode, and then Press F5 (INFO) to check DTC's information from the DTCs menu. 4. Read "DTC Status" parameter. Fig 5: Scan Tool Screen Display - DTC Status 5. Is "Present" Fault displayed? 1. Go to "SYSTEM INSPECTION " procedure. 1. Fault is intermittent caused by ECM memory was not cleared after repair. Erase DTC and drive the vehicle to satisfy the enable condition then, go to "SYSTEM INSPECTION " procedure.

Page 4 of 7 System Inspection 1. Visual Inspection 1. Check oil level is O.K. 2. Check for contamination of engine oil and OCV 3. Has a problem been found? 1. Repair or replace as necessary and then, go to "VERIFICATION OF VEHICLE REPAIR " procedure. 1. Go to step 2. 2. Visually check CKPS and target wheel 1. IG "OFF" 2. Visually check CKPS is loosened or target wheel is deformed or damaged. 3. Are normal conditions present? 1. Go to step 3. 1. Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure. 3. Check CAM PHASER with actuation test 1. Connect scan tool and IG "ON" 2. Select "CAM PHASER INTAKE BANK 1" on the Actuation Test 3. Select "OIL CONTROL VALVE" on the Actuation Test 4. Activates "CAM PHASER INTAKE BANK 1" by pressing "STRT (F1)" key 5. Activates "OIL CONTROL VALVE" by pressing "STRT (F1)" key 6. Repeat this procedure 4 or 5 times to ensure CAM PHASER and intake valve control solenoid reliability

Substitute with a known-good CVVT or OCV and check for proper operation. If the problem is corrected, replace CVVT or OCV and go to "VERIFICATION OF VEHICLE REPAIR ". 1. Fault is intermittent. Drive the vehicle to meet the enable condition for the DTC and Go to "COMPONENT INSPECTION ". 1. IG "OFF" and connect scan tool. 2. ENG "ON" and Measure signal waveform at terminal 3 of CMPS. 3. Measure signal waveform at terminal 1 or 2 of CKPS. Specification: 17th signal of the CKPS after missing tooth is aligned with the high signal of the CMPS at idle, ECM recognizes that Synchronization between CKPS and CMPS is completed.

Page 6 of 7 4. Is the measured signal waveform O.K? 2. Timing Mark Inspection. 1. Fault is intermittent. Drive the vehicle to meet the enable condition for the DTC and Go to "VERIFICATION OF VEHICLE REPAIR ". 1. Go to step 2. 1. IG "OFF" and check for correct timing mark alignment. REFERENCE: Fig 8: Identifying Timing Mark 2. Is the timing mark correctly aligned? VERIFICATION OF VEHICLE REPAIR 1. Fault is intermittent. Drive the vehicle to meet the enable condition for the DTC and Go to "VERIFICATION OF VEHICLE REPAIR " procedure. 1. Repair or replace as necessary and then, go to "VERIFICATION OF VEHICLE REPAIR " procedure. After a repair, it is essential to verify that the fault has been corrected.

Page 7 of 7 1. Connect scan tool and select "Diagnostic Trouble Codes (DTCs)" mode 2. Press F5 (INFO) and confirm that "DTC Readiness Flag" indicates "Complete". If not, drive the vehicle within conditions noted in the freeze frame data or enable conditions 3. Read "DTC Status" parameter 4. Is "History (Not Present)" fault displayed? 1. System performing to specification at this time. Clear the DTC 1. Go to the applicable troubleshooting procedure.
