P0201 on Dacia by model: symptoms, diagnosis and fix
The K9K 1.5 dCi diesel — used across Dacia Sandero, Duster, Logan, plus Renault Clio/Captur/Kadjar, Nissan Note/Juke — suffers Bosch CP1 high-pressure pump and injector failure typically at 100,000-180,000 km. Worst case: pump self-destructs and sends metal particles through the entire fuel system, requiring full rail+pump+injector replacement (€2,500-€4,000).
Common Symptoms
- rough start
- misfire
- limp mode
- fuel smell
- no start
How to Fix
Back-leak test at 80,000 km as a precaution. Single-injector replacement €250-€500. If pump has failed catastrophically, full system flush + replacement is the only safe option. Use only diesel from major-brand stations and add a fuel-system cleaner per service.

Frequently asked questions
What does P0201 mean on a Dacia?
P0201 stands for "Injector Circuit/Open - Cylinder 1." P0201 means the engine computer detected an electrical problem in the wiring or control circuit for the fuel injector on cylinder 1. The PCM pulses each injector open and back ground, and when it sees an open circuit, a short, or abnormal resistance on cylinder 1's injector circuit, it sets this code. In practice it means cylinder 1 may not be getting fuel injected properly, which can cause a misfire, rough running, or a no-start on that cylinder. It points to the injector itself or its wiring, not to a fuel-pressure problem affecting the whole engine. On Dacia it is documented across 1 model: Sandero.
What are the most common causes of P0201?
The most common causes of P0201 are: Damaged or corroded injector connector or terminals at cylinder 1, Broken, chafed, or shorted injector wiring harness, Failed (open or shorted) fuel injector on cylinder 1, Loose or poor ground/power feed to the injector circuit, Blown injector fuse or relay feeding the bank, Failed injector driver inside the PCM/ECM. The specific cause varies by vehicle.
How much does it cost to fix P0201 on a Dacia?
Published repair estimates on Dacia range from $250 to $4,000 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
