DTC P0016 CRANKSHAFT POSITION-CAMSHAFT POSITION CORRELATION (BANK 1 SENSOR A)Component Location:
COMPONENT LOCATION
GENERAL DESCRIPTION
The Camshaft Position Sensor (CMPS) and the Crankshaft Position Sensor (CKPS) are a hall effect type sensors that generate voltage using a sensor and a target wheel. The CMPS signal is sent to the PCM and the PCM uses the its signal for synchronizing the firing of sequential fuel injectors.And the Crankshaft Position Sensor (CKPS) is sent to the PCM and it calculates engine RPM by using the CKPS'S signal and controls the injection duration and the ignition timing.
DTC DESCRIPTION
If the relative angle between CKPS and CMPS is out of the threshold value, the PCM determines that a fault exists and a DTC is stored.
DTC Detecting Condition:
Signal Waveform & Data:
Schematic Diagram:
MONITOR SCANTOOL DATA
1. Ignition "OFF" & Engine "OFF"
2. Install Scantool and Ignition "ON" & Engine "ON"
3. Monitor that Signal waveform of CKPS and CMPS is correctly aligned.
4. Are both CKPS and CMPS is correctly synchronized with?
YES: Fault is intermittent caused by poor contact in the sensor's and/or PCM's connector or was repaired and PCM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure.
NO: Go to "Component Inspection" procedure.
COMPONENT INSPECTION
1. Check sensor installation
1. Ignition "OFF"
2. Disconnect CMPS,CKPS
3. Check CKPS and CMPS for deformation, proper installation.
4. Are all CKPS and CMPS installed well?
YES: Go to "Check Timing Marks" as below.
NO: Repair or replace as necessary and then, go to "Verification of Vehicle Repair" procedure.
2. Check Timing Marks
1. Ignition "OFF"
2. Check that Timing Marks on both sprockets are correctly aligned with align marks.
3. Are the timing marks for both CAM and Crankshaft sprockets correctly aligned with?
YES:
- Substitute with a known - good PCM and check for proper operation.
- If the problem is corrected, replace PCM and go to "Verification of Vehicle Repair" procedure.
NO: Repair or replace as necessary and then, go to "Verification of Vehicle Repair" procedure.
VERIFICATION OF VEHICLE REPAIR
After a repair, it is essential to verify that the fault has been corrected.
1. Monitor and record the Freeze Frame Data for the Diagnostic Trouble Code(DTC) which has been diagnosed.
2. Using a Scantool, Clear the DTCs.
3. Operate the vehicle within conditions noted in the freeze frame data or enable conditions.
4. Monitor that all readiness tests have been verified as "Complete"
5. Are any DTCs present?
YES: Go to the applicable troubleshooting procedure.
NO: System is performing to specification at this time.
