P0208 on Ford
Injector Circuit/Open - Cylinder 8
P0208 on Ford vehicles indicates injector circuit/open - cylinder 8. Au7o has documented this code across 1 Ford model — most commonly on F-250. This code means the engine computer detected an open or out-of-range condition in the fuel injector circuit for cylinder 8. Fuel injectors are electrically operated valves, and the computer continuously checks that each one's circuit responds correctly when commanded to open. When cylinder 8's injector circuit reads as broken, shorted, or electrically abnormal, this code sets — frequently accompanied by a misfire or rough running on that cylinder. The fault is electrical (wiring, connector, or the injector itself), not a fuel-supply issue. Typical repair costs on Ford range from $800 to $2,500, depending on the specific model and root cause.
Common Causes of P0208
- •Corroded, loose, or damaged injector connector at cylinder 8
- •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
P0208 on Ford by Model
Ford F-250(1 issue)
- 7.3L IDI/Powerstroke Injector Failure1990-1998
The 7.3L diesel engines (IDI pre-1994, Powerstroke 1994+) experience injector failure causing rough running, hard starts, and excessive smoke. The IDI injectors are simpler mechanical units; Powerstroke uses HEUI hydraulic electronic injectors.

What does P0208 mean on Ford?▼
P0208 stands for "Injector Circuit/Open - Cylinder 8." This code means the engine computer detected an open or out-of-range condition in the fuel injector circuit for cylinder 8. Fuel injectors are electrically operated valves, and the computer continuously checks that each one's circuit responds correctly when commanded to open. When cylinder 8's injector circuit reads as broken, shorted, or electrically abnormal, this code sets — frequently accompanied by a misfire or rough running on that cylinder. The fault is electrical (wiring, connector, or the injector itself), not a fuel-supply issue. On Ford specifically, this code is documented across 1 model.
