OBD-II (EN): Crankshaft Position Sensor Signal No Signal or Out of Range
Code P1920 in Audi and Volkswagen vehicles indicates a problem with the crankshaft position sensor — a key component for engine management. This could be a fault of the sensor itself, wiring damage, or a problem with the reluctor ring. Due to the risk of sudden engine stalling while driving, prompt diagnosis at an authorized service center or workshop with VAG software is recommended.
Symptoms
Illuminated Check Engine (MIL) light, difficulty starting the engine or inability to start, sudden engine stalling while driving, jerking and rough engine operation, significant power reduction (limp mode), sudden misfiring, increased fuel consumption.
Possible causes
• Faulty or worn Crankshaft Position (CKP) sensor • Open or short circuit in the wiring harness leading to the sensor • Damaged reluctor ring (tone wheel) on the crankshaft — broken or deformed teeth • Excessive dirt or gap between the sensor and reluctor ring • Malfunctioning ECU/engine control module (rare, after excluding the above)
