P0341 on SEAT
Camshaft Position Sensor Circuit Range/Performance (Bank 1)
P0341 on SEAT vehicles indicates camshaft position sensor circuit range/performance (bank 1). Au7o has documented this code across 1 SEAT model — most commonly on Leon. This code means the camshaft position sensor on Bank 1 is sending a signal that is present but doesn't make sense to the engine computer (a range/performance fault), often because it disagrees with the crankshaft position signal. The cam sensor tells the computer where the camshaft is so it can correctly time fuel injection and spark, and on engines with variable valve timing it also confirms cam phaser movement. When the signal is out of range, intermittent, or doesn't correlate properly, the computer flags this code, and you may notice hard starting, rough running, or reduced power. Causes are commonly a worn sensor, a stretched timing chain, or a problem with the cam phaser/tone ring. Typical repair costs on SEAT range from $600 to $1,800, depending on the specific model and root cause.
Common Causes of P0341
- •Failed or weak camshaft position sensor
- •Damaged or corroded sensor wiring/connector
- •Stretched or worn timing chain causing cam timing drift
- •Faulty variable valve timing (VVT) cam phaser or solenoid
- •Damaged camshaft reluctor (tone) ring
- •Low or dirty engine oil affecting VVT operation
- •Incorrect sensor air gap or installation
- •Faulty PCM/ECM (rare)
P0341 on SEAT by Model
SEAT Leon(1 issue)
- 1.2/1.4 TSI (EA111) Timing Chain Stretch and Tensioner Failure2008-2014
Early petrol Leons fitted with the EA111-family 1.2 and 1.4 TSI engines (CBZ/CAVx/CTHx etc.) are well documented for premature timing chain stretch and tensioner failure. The chain tensioner can lose pressure and let the chain go slack, causing a loud rattle on cold start and, in worst cases, the chain skipping teeth and causing valve-to-piston contact. Failures are widely reported well before 60,000 miles (often 30k-60k). This affects Mk2 (1P) and very early Mk3 (5F) cars before VW moved to the revised EA211 chain/belt setup.

What does P0341 mean on SEAT?▼
P0341 stands for "Camshaft Position Sensor Circuit Range/Performance (Bank 1)." This code means the camshaft position sensor on Bank 1 is sending a signal that is present but doesn't make sense to the engine computer (a range/performance fault), often because it disagrees with the crankshaft position signal. The cam sensor tells the computer where the camshaft is so it can correctly time fuel injection and spark, and on engines with variable valve timing it also confirms cam phaser movement. When the signal is out of range, intermittent, or doesn't correlate properly, the computer flags this code, and you may notice hard starting, rough running, or reduced power. Causes are commonly a worn sensor, a stretched timing chain, or a problem with the cam phaser/tone ring. On SEAT specifically, this code is documented across 1 model.
What causes P0341 on SEAT vehicles?▼
