P0202 on Ford by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Rough running and engine misfires
- Poor idle quality
- Excessive blue or black smoke on cold start
- Reduced engine performance and power
- Check engine light with injector or misfire codes
- Engine stalls immediately after starting
- High fuel consumption
- Engine hesitation under acceleration
How to Fix
For Transit 3.5L EcoBoost: replace failed injectors ($100-200 per injector, 3-4 hours labor). Consider replacing all 6 injectors if the vehicle has over 100k miles - if one has failed, others are likely close behind. For EcoBlue diesel: Ford issued a service action for Continental injector failures - check with dealer for coverage. Use only Top Tier gasoline and change fuel filters per schedule. Professional fuel system cleaning every 50,000 miles can extend injector life.

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.
Common Symptoms
- Hard starting
- Black or white smoke
- Rough idle
- Knocking noise
- Loss of power

Frequently asked questions
What does P0202 mean on a Ford?
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 Ford it is documented across 2 models: Transit, F-250.
What are the most common causes of P0202?
The most common causes of P0202 are: 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. The specific cause varies by vehicle.
How much does it cost to fix P0202 on a Ford?
Published repair estimates on Ford range from $300 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.
