P0017 on Citroen
Crankshaft/Camshaft Position Correlation - Bank 1 Sensor B
P0017 on Citroen vehicles indicates crankshaft/camshaft position correlation - bank 1 sensor b. Au7o has documented this code across 2 Citroen models — most commonly on C3, DS3. This code means the engine computer has detected that the crankshaft and the Bank 1 'B' camshaft (typically the exhaust camshaft) are out of their proper timing relationship with each other. The computer compares the crankshaft position signal to the camshaft position signal, and when they don't line up within the allowed window, it sets this correlation code. This usually points to mechanical timing being off, most often from a stretched or worn timing chain, a slipped or stuck variable valve timing phaser, or a tensioner problem. You may notice rough running, low power, rattling at startup, or a no-start, and it should be addressed promptly to avoid valve-to-piston contact on some engines. Typical repair costs on Citroen range from $800 to $2,000, depending on the specific model and root cause.
Common Causes of P0017
- •Stretched or worn timing chain
- •Worn or failed timing chain tensioner or guides
- •Stuck or faulty variable valve timing (VVT) cam phaser
- •Faulty VVT oil control/solenoid valve
- •Low or dirty engine oil affecting phaser operation
- •Faulty camshaft or crankshaft position sensor
- •Timing chain jumped a tooth or incorrect timing after service
- •Damaged reluctor (tone) ring
P0017 on Citroen by Model
Citroen C3(1 issue)
- PureTech 1.2 Wet Timing Belt Delamination2014-2026
PSA/Stellantis PureTech 1.2 (EB2) engines run an oil-immersed ("wet") timing belt instead of a chain. The belt's outer rubber layer can delaminate and shed particles into the oil pickup, clogging the strainer and starving the engine of oil. Stellantis revised the belt material and shortened the service interval (now 60,000 mi or 6 years, whichever first) but earlier-spec belts still in service are at risk.
Citroen DS3(1 issue)
- Timing Chain Tensioner Failure2010-2019
The DS3 uses the PSA/BMW Prince engine family, which has the well-documented timing chain tensioner failure. The hydraulic tensioner loses pressure, allowing chain slack that leads to timing skip and potential engine destruction.

What does P0017 mean on Citroen?▼
P0017 stands for "Crankshaft/Camshaft Position Correlation - Bank 1 Sensor B." This code means the engine computer has detected that the crankshaft and the Bank 1 'B' camshaft (typically the exhaust camshaft) are out of their proper timing relationship with each other. The computer compares the crankshaft position signal to the camshaft position signal, and when they don't line up within the allowed window, it sets this correlation code.

You may notice rough running, low power, rattling at startup, or a no-start, and it should be addressed promptly to avoid valve-to-piston contact on some engines. On Citroen specifically, this code is documented across 2 models.
