P0366 on Volkswagen
Camshaft Position Sensor "B" Circuit Range/Performance (Bank 1)
P0366 on Volkswagen vehicles indicates camshaft position sensor "b" circuit range/performance (bank 1). Au7o has documented this code across 1 Volkswagen model — most commonly on Passat. This code indicates the 'B' camshaft position sensor on Bank 1 is electrically present but its signal is out of the expected range or inconsistent with the crankshaft position signal. The PCM uses this sensor to track camshaft timing for fuel, spark, and variable valve timing control. A range/performance fault can cause rough idle, hesitation, reduced power, or hard starting. It often points to sensor or timing alignment issues rather than a fully open circuit. Typical repair costs on Volkswagen range from $1,500 to $3,500, depending on the specific model and root cause.
Common Causes of P0366
- •Failing camshaft position sensor (Bank 1, sensor B)
- •Damaged reluctor/tone ring or excessive air gap
- •Timing chain/belt stretch or jumped timing
- •Wiring/connector intermittent fault or corrosion
- •Oil contamination on the sensor
- •Variable valve timing actuator fault
P0366 on Volkswagen by Model
Volkswagen Passat(1 issue)
- Timing Chain Tensioner Failure (2.0T TSI)2008-2017
The Passat shares the same EA888 2.0T TSI timing chain tensioner issue as other VW/Audi models. The original tensioner design allows the chain to go slack when the engine is off, and on restart the chain can skip timing. Early revisions of the tensioner were inadequate and VW issued multiple updated part numbers. The Passat is particularly affected in the 2008-2014 model years.

What does P0366 mean on Volkswagen?▼
P0366 stands for "Camshaft Position Sensor "B" Circuit Range/Performance (Bank 1)." This code indicates the 'B' camshaft position sensor on Bank 1 is electrically present but its signal is out of the expected range or inconsistent with the crankshaft position signal. The PCM uses this sensor to track camshaft timing for fuel, spark, and variable valve timing control. A range/performance fault can cause rough idle, hesitation, reduced power, or hard starting. It often points to sensor or timing alignment issues rather than a fully open circuit. On Volkswagen specifically, this code is documented across 1 model.
What causes P0366 on Volkswagen vehicles?▼
Common causes on Volkswagen: Failing camshaft position sensor (Bank 1, sensor B), Damaged reluctor/tone ring or excessive air gap, Timing chain/belt stretch or jumped timing, Wiring/connector intermittent fault or corrosion, Oil contamination on the sensor. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0366 on a Volkswagen?▼
