DTC Code P1347 – What does this code mean for Volkswagen?

<ul> <li><b>Engine Light ON</b>: The Engine Light or Service Engine Soon Warning Light illuminates, indicating an issue with the camshaft and crankshaft position sensors on Bank 2. This can be caused by incorrect sensor allocation or a misalignment between the camshaft and crankshaft positions.</li> <li><b>Engine Misfire</b>: The engine may experience misfires due to incorrect timing information being sent to the ECU. This can result from the camshaft and crankshaft position sensors being incorrectly allocated or misaligned.</li> <li><b>Poor Engine Performance</b>: The vehicle may exhibit poor engine performance, including reduced power and acceleration. This is often due to the ECU receiving incorrect timing data from the misallocated sensors.</li> <li><b>Rough Idling</b>: The engine may idle roughly or inconsistently, which can be attributed to the incorrect allocation of the camshaft and crankshaft position sensors affecting the engine's timing.</li> <li><b>Difficulty Starting</b>: The vehicle may have difficulty starting, as the incorrect sensor allocation can disrupt the synchronization between the camshaft and crankshaft, leading to improper ignition timing.</li> </ul>

<ul><li>Engine speed sensors may be malfunctioning, leading to incorrect readings and triggering the error code.</li><li>Engine mechanical timing issues, such as a misaligned timing belt or chain, can cause discrepancies between the camshaft and crankshaft positions.</li></ul>

<ul> <li><b>Initial Scan</b>: Use an OBD-II scanner to confirm the presence of DTC P1347 and check for any additional codes.</li> <li><b>Visual Inspection</b>: Inspect the wiring and connectors related to the camshaft and crankshaft position sensors for any signs of damage, corrosion, or disconnection.</li> <li><b>Check Sensor Alignment</b>: Verify the alignment of the camshaft and crankshaft position sensors. Ensure they are correctly positioned and not misaligned.</li> <li><b>Test Camshaft Position Sensor</b>: Use a multimeter to test the camshaft position sensor on Bank 2 for proper voltage and resistance according to the manufacturer's specifications.</li> <li><b>Test Crankshaft Position Sensor</b>: Similarly, test the crankshaft position sensor for proper voltage and resistance. Compare the readings with the manufacturer's specifications.</li> <li><b>Check Timing</b>: Inspect the engine timing to ensure that the camshaft and crankshaft are correctly synchronized. Misalignment can cause this DTC.</li> <li><b>ECU Check</b>: Check the Engine Control Unit (ECU) for any software updates or faults that could be causing incorrect sensor allocation.</li> <li><b>Replace Faulty Components</b>: If any sensors or wiring are found to be faulty, replace them and clear the codes. Re-scan to ensure the issue is resolved.</li></ul>

<p>The DTC code P1347 for Volkswagen indicates a <b>Bank 2 Camshaft Position/Crankshaft Position Sensor Wrong Allocation</b>. This is a critical issue as it affects the engine's timing and can lead to severe engine damage if not addressed immediately.</p><ul><li>Immediate action: Inspect and realign the camshaft and crankshaft position sensors.</li><li>Potential risks: Engine misfires, poor performance, and potential engine failure.</li></ul>
