P0201 on Dacia
Injector Circuit/Open - Cylinder 1
P0201 on Dacia vehicles indicates injector circuit/open - cylinder 1. Au7o has documented this code across 1 Dacia model — most commonly on Sandero. 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. Typical repair costs on Dacia range from $250 to $4,000, depending on the specific model and root cause.
Common Causes of P0201
- •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
P0201 on Dacia by Model
Dacia Sandero(1 issue)
- Sandero / Duster 1.5 dCi K9K Bosch CP1 Injector Failure2008-2020
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).

What does P0201 mean on 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 specifically, this code is documented across 1 model.
