P0201 on Ford
Injector Circuit/Open - Cylinder 1
P0201 on Ford vehicles indicates injector circuit/open - cylinder 1. Au7o has documented this code across 2 Ford models — most commonly on F-250, Transit. 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 Ford range from $300 to $2,500, 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 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.
Ford Transit(1 issue)
- Fuel Injector Failure and Rough Running (EcoBlue Diesel)2017-2023
The 2017-2023 Ford Transit with the 2.0L EcoBlue diesel engine (available in some markets) and the 3.5L EcoBoost V6 experience fuel injector failures causing rough running, misfires, poor idle, reduced performance, and excessive smoke on cold start. Parkers UK documents an official Ford service action for Transit EcoBlue diesel injector failures traced to a quality issue with Continental-supplied injectors where an internal surface coating comes unstuck, blocking the injector. FordTransitUSAForum.com documents injector failure on 3.5L EcoBoost Transit models as well, where direct injection fuel deposits cause injector spray pattern degradation. RepairPal estimates individual injector replacement between $266 and $627 depending on Transit model, but multiple injectors often need replacement simultaneously, and contaminated fuel systems can cost significantly more.

What does P0201 mean on Ford?▼
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 Ford specifically, this code is documented across 2 models.
What causes P0201 on Ford vehicles?▼
Common causes on Ford: 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. Specific causes vary by model and year — see the per-model sections below.
