Causes

Timing chain/belt jumped teeth or incorrect timing installation
Worn or failed timing chain tensioner, guides, or sprockets
Faulty camshaft position sensor (bank 1 sensor 2) or crankshaft position sensor
Damaged or corroded wiring or connectors to cam/crank sensors
Variable valve timing (VVT) actuator/solenoid stuck, leaking, or not actuating
Low engine oil level, dirty oil, or low oil pressure affecting VVT operation

Symptoms

Malfunction Indicator Lamp (MIL) / Check Engine Light illuminated
Rough idle, misfires or vibration
Reduced engine power or poor acceleration
Hard starting or stalling
Decreased fuel economy
Unusual engine noise (rattle or clatter) from front of engine

What to check

Read freeze frame and stored data with a capable scan tool; note related codes
Check engine oil level and condition; verify correct viscosity and service interval
Visual inspection of wiring and connectors for camshaft and crankshaft sensors (bank 1 sensor 2)
Inspect for signs of recent timing service or repairs (incorrect assembly)
Use scan tool to view live camshaft position vs crankshaft position correlation data
Capture sensor waveforms (oscilloscope) for cam and crank sensors and verify pattern and phase

Signal parameters

Camshaft position sensor: digital/Hall or variable reluctance pattern; typical voltage swing 0–5 V (square wave) or AC millivolt signal for VR sensors
Crankshaft position sensor: digital/Hall or VR; frequency increases with RPM, voltage 0–5 V (digital) or AC for VR
Expected phase relationship: camshaft signal transitions should occur at defined crankshaft angles — PCM flags correlation when deviation exceeds calibrated threshold (often measured in degrees of crankshaft rotation)
At idle the cam signal should show a steady, repeatable phase relative to crank pulses; intermittent or missing cam pulses indicate sensor/circuit or mechanical timing issues
No-load frequency/duty varies with RPM; open/shorted sensor circuits often show fixed or no waveform

Diagnostic algorithm

Retrieve all DTCs and freeze-frame data. Note engine rpm and temperature when fault set; inspect for related codes (P0016, P0014, P0340, P0335, etc.).
Verify oil level and condition. Low or dirty oil can prevent VVT actuators from working correctly — top up or change oil if necessary and retest.
Visually inspect camshaft and crankshaft sensor connectors and wiring for damage, corrosion, bent pins or poor mating. Repair any faults and clear codes to retest.
Using a scan tool, monitor live camshaft and crankshaft position data (CMP vs CKP). Look for inconsistent correlation, missing pulses, or signals that change with commanded VVT.
Capture waveforms from CMP (bank 1 sensor 2) and CKP with an oscilloscope. Verify signal shape, amplitude, and phase relationship. Compare to known-good pattern or factory specifications.
Command VVT solenoids and observe oil control valve movement and camshaft position response (if supported by tool). If actuator does not respond electrically, check supply, ground and control circuits.
If sensor/wiring tests good but correlation error remains, remove timing cover or inspect timing assembly to confirm timing marks, chain/belt condition, tensioner and guides. Repair or replace any worn or jumped components.
If mechanical timing is confirmed correct and sensors/wiring good, consider PCM software updates or ECU fault. Replace defective VVT actuators, sensors, or PCM only after confirming root cause.
After repairs, clear codes, perform any required cam/crank relearn or adaptation procedures per manufacturer instructions, then road test and re-scan to confirm repair.

Likely causes

Timing chain has jumped or stretched resulting in cam/crank phase shift
Faulty or intermittent camshaft position sensor (bank 1 sensor 2) or its wiring
VVT actuator/solenoid stuck or not responding due to oil contamination or electrical fault
Worn tensioner or guides allowing timing drift
Low/contaminated oil preventing proper VVT operation
