Frequently asked questions
What does P0207 mean on a Ford?
P0207 stands for "Injector Circuit/Open - Cylinder 7." This code indicates the engine computer found an electrical fault — an open or out-of-range circuit — in the fuel injector wiring for cylinder 7. The injector is a solenoid-operated valve, and the computer watches its circuit to verify it's firing on command. A break, short, or high resistance on cylinder 7's injector circuit triggers this code, often with a noticeable misfire or rough idle on that cylinder. The problem lies in the injector itself or its electrical connection, not in fuel pressure or quality. On Ford it is documented across 1 model: F-250.
What are the most common causes of P0207?
The most common causes of P0207 are: Corroded, loose, or damaged injector connector at cylinder 7, Open, shorted, or chafed wiring in the injector circuit, Failed fuel injector (open internal winding), Poor ground or power feed to the injector driver, Failed injector driver circuit inside the ECM/PCM, Water intrusion or pin corrosion in the engine harness. The specific cause varies by vehicle.
How much does it cost to fix P0207 on a Ford?
Published repair estimates on Ford range from $800 to $2,500 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.
