P1347 · VolkswagenBank 2 Crankshaft Camshaft Position Sensor Signal Out Of Sequence

P1347 on Volkswagen vehicles indicates that the engine control module (ECM) has detected an out-of-sequence signal between the bank 2 crankshaft position sensor and the bank 2 camshaft position sensor. The ECM expects the camshaft and crankshaft signals to correlate within a specific timing window, and this code sets when the camshaft signal arrives outside that expected window relative to the crankshaft signal.

Symptoms you may notice

Illuminated check engine light, often with no other noticeable symptoms
Rough idle or misfire, particularly noticeable at low engine speeds
Reduced engine performance or lack of power during acceleration
Difficulty starting or extended cranking times
Intermittent stalling or engine cut-out while driving
Poor fuel economy or increased emissions

Common causes, most likely first

Faulty bank 2 camshaft position sensor or its wiring/connector
Faulty bank 2 crankshaft position sensor or its wiring/connector
Stretched timing chain or worn timing chain tensioner causing camshaft timing deviation
Contaminated or damaged sensor reluctor wheel or tone ring
Engine oil sludge or debris interfering with sensor signal
ECM software issue or faulty ECM (less common)

How to diagnose and fix it

Perform a visual inspection of the bank 2 camshaft and crankshaft sensor wiring and connectors for damage or corrosion
Use a scan tool to check for other stored codes and freeze-frame data to confirm the fault conditions
Check sensor resistance and signal output with a multimeter or oscilloscope according to Volkswagen specifications
Verify timing chain condition and timing marks alignment to rule out mechanical timing issues
Replace the bank 2 camshaft position sensor if testing indicates it is faulty
Replace the bank 2 crankshaft position sensor if testing indicates it is faulty
If mechanical timing is off, repair or replace timing chain components as needed and clear codes to verify the fix

Timing Chain Stretch Often Mimics Sensor Failure

A stretched timing chain on Volkswagen engines can cause the camshaft to lag behind the crankshaft, setting P1347 even when both sensors are functioning correctly.
The bank 2 camshaft position sensor on some Volkswagen engines is difficult to access and its wiring can be damaged by heat or oil leaks, leading to intermittent signals.
P1347 can be set by a dirty or damaged reluctor wheel on the camshaft or crankshaft, which is often overlooked when replacing sensors.
After replacing a sensor, the ECM may require a adaptation or relearn procedure to correctly interpret the new signal.
This code does not always indicate a sensor failure; mechanical issues such as a worn timing chain tensioner should be ruled out before parts replacement.

Can I keep driving with P1347?

Driving with P1347 is possible but not recommended for extended periods, as it can lead to poor engine performance and potential damage if the timing chain is stretched. Avoid heavy acceleration and high-speed driving, and have the vehicle diagnosed promptly to prevent worsening of the fault.
