Causes
- Timing chain/belt slipped or jumped teeth
- Damaged or incorrect crankshaft or camshaft reluctor/wheel
- Faulty camshaft position sensor (Bank 1, Sensor A)
- Faulty crankshaft position sensor
- Wiring fault or poor connector (open/short/intermittent) to either sensor
- Faulty or stuck variable valve timing (VVT) actuator or oil control valve
Symptoms
- Check Engine Light (MIL) with code P0016 stored
- Rough idle or intermittent misfire
- Hard starting or no-start condition
- Loss of power or reduced engine performance
- Poor fuel economy
- Engine stalls or runs irregularly
What to check
- Read and record freeze frame and live data (cam/crank correlation and engine speed)
- Confirm code is current (pending vs confirmed) and attempt to re-create
- Visually inspect sensor connectors and wiring for damage, corrosion, or loose pins
- Check engine oil level and condition (VVT systems sensitive to oil)
- Backprobe sensor power, ground and signal with a multimeter/oscilloscope
- Compare cam and crank sensor waveforms simultaneously with an oscilloscope
Signal parameters
- Hall-effect sensors: 0–5 V squarewave, 50% duty varying with timing; reference 5 V supply and ground
- Variable reluctor (VR) sensors: low-voltage AC signal, amplitude rising with rpm (typical 0.2–3 V RMS)
- Crank sensor produces multiple pulses per engine revolution (depends on tone wheel), cam sensor typically produces one pulse per two crank revolutions for reference
- Expected relationship: cam reference event occurs at a fixed phase relative to crank pulses; ECM tolerance commonly in the range of ~10–30° crank degrees (manufacturer-specific)
- Intermittent missing pulses, shifted phase, or inconsistent amplitude indicate sensor/reluctor/wiring/mechanical timing faults
Diagnostic algorithm
- Retrieve freeze frame, stored codes and live data. Note engine speed and whether code appears at idle or under load.
- Clear codes and attempt to re-run to confirm repeatability. If intermittent, monitor while driving.
- Visually inspect connectors and wiring for both cam and crank sensors; repair any damaged wiring, corrosion, or loose pins.
- Verify sensor supply voltage and ground at the connector (typically switched 5 V or battery/ignition reference and chassis ground).
- Capture simultaneous cam and crank sensor waveforms with an oscilloscope. Look for missing pulses, noisy signals, shifted phase, or amplitude loss.
- If waveforms are bad for a sensor, bench-test or replace the sensor and re-test. If waveforms are good electrically, continue mechanical checks.
- Inspect reluctor/tone wheel for damage, missing teeth, or movement relative to the shaft. Repair or replace as needed.
- Verify mechanical timing: remove covers if required and check timing belt/chain alignment marks and tension. Correct timing if slipped.
- Check VVT components: test oil control valve operation, actuator movement, and oil passages. Low oil pressure or clogged passages can cause incorrect cam timing.
- If mechanical timing and sensor signals are correct but code persists, inspect for internal timing component wear (cam phasers, timing chain guides) and replace as necessary.
- As a last step, consider ECM diagnostic/flash or replacement if all sensors, wiring and mechanical timing check good and no other causes found.
Likely causes
- Timing chain/belt jumped or stretched (mechanical timing off)
- Intermittent or failed camshaft or crankshaft position sensor
- Damaged or missing teeth on tone/reluctor wheel
- Faulty VVT actuator or stuck oil control valve affecting cam timing
- Wiring/connector issue between sensors and ECM
Fault status
Status
Camshaft position - crankshaft position correlation error detected for Bank 1 Sensor A. The ECM has detected the cam signal is not in expected phase relationship to the crank signal.
Repair difficulty: Hard
Diagnostic time: 2-6 hours
