P0200: Injector circuit malfunction
The ECU has found an electrical fault in the injector circuit without naming a specific cylinder. Often a fuse, a relay or the shared wiring.
| Code | P0200 |
|---|---|
| System | Engine and transmission |
| Group | P02xx, Fuel and injectors |
| Type | Generic: it means the same on every make |
| Can you keep driving? | With care |
What P0200 means
Each injector opens and closes on an electrical signal from the ECU. This general code says something is wrong in that circuit without saying which cylinder. The fault is often in a part shared by all injectors, such as their power supply, and it usually comes with other more specific codes.
Most common causes
- Blown fuse or faulty injector supply relay
- Loose or corroded connector on one of the injectors
- Injector wiring harness damaged by rubbing or heat
- One or more injectors with a failed coil
- Fault in the driver circuit inside the ECU
Symptoms
- Engine warning light on
- Engine shaking or running unevenly
- Loss of power
- Hard starting or no start
Can you drive with P0200?
With care If the engine runs smoothly you can drive carefully to a garage. If it shakes badly, loses power or the warning light flashes, stop driving to avoid damaging the engine or the catalytic converter.

How to check it
Read all stored codes, not just this one: injector or misfire codes for a specific cylinder (P0201 to P0208, P0301 to P0308) show where to start. Also check the injector fuse in the fuse box.
How to read and clear P0200 with Final OBD
Plug an OBD2 scanner in under the steering wheel, switch the ignition on and open Final OBD. Under Faults you’ll see P0200 with its description and whether it’s confirmed, pending or permanent.
If the engine stores it over standard OBD, with FREE you read this code with its explanation for nothing and clear it. With PRO you also read the faults of every control unit and clear them in all of them.
Clearing the code only turns the light off: if the cause is still there, it comes back. Clear it once it’s fixed, and not right before an inspection. It’s all in how to read and clear fault codes and in inspections and OBD.

How do you clear P0200?
With an OBD2 scanner and an app like Final OBD, which clears it for free if it’s stored by the engine control unit. But clearing it only turns the light off: if the cause isn’t fixed, P0200 comes back.
Read it on your car
Final OBD reads and clears engine faults through standard OBD for free, each one explained in plain English. With PRO it also reads the faults of every control unit, each make’s own codes included, and clears them in all of them.
