P0202 on Dacia
Injector Circuit/Open - Cylinder 2
P0202 on Dacia vehicles indicates injector circuit/open - cylinder 2. Au7o has documented this code across 1 Dacia model — most commonly on Sandero. This code means the Engine Control Module detected an electrical problem (open circuit or out-of-range resistance) in the fuel injector control circuit for cylinder 2. The ECM switches each injector on and off through this circuit, and it monitors the circuit to confirm the injector is responding. P0202 indicates the computer isn't getting the expected electrical feedback for that specific injector, so cylinder 2 may not be fueling correctly. This commonly causes a misfire, rough running, and reduced power on that cylinder. Typical repair costs on Dacia range from $250 to $4,000, depending on the specific model and root cause.
Common Causes of P0202
- •Damaged or corroded injector connector at cylinder 2
- •Open or shorted wiring in the injector control circuit
- •Failed (electrically open) fuel injector on cylinder 2
- •Loose or backed-out connector pin
- •Poor ground or power feed to the injector
- •Faulty injector driver inside the ECM/PCM
- •Chafed harness causing intermittent open
P0202 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 P0202 mean on Dacia?▼
P0202 stands for "Injector Circuit/Open - Cylinder 2." This code means the Engine Control Module detected an electrical problem (open circuit or out-of-range resistance) in the fuel injector control circuit for cylinder 2. The ECM switches each injector on and off through this circuit, and it monitors the circuit to confirm the injector is responding. P0202 indicates the computer isn't getting the expected electrical feedback for that specific injector, so cylinder 2 may not be fueling correctly. This commonly causes a misfire, rough running, and reduced power on that cylinder. On Dacia specifically, this code is documented across 1 model.
