P0207 Injector Circuit/Open - Cylinder 7
P0207 is a generic OBD2 powertrain code. It means “Injector Circuit/Open - Cylinder 7” — the same on every make and model, because the definition comes from the SAE J2012 standard rather than from the carmaker.

What the wording tells you
“Open” means the module found a break in the circuit — no current flowing where there should be. Check the connector (unplugged, corroded, a pushed-back pin), the wire, the fuse and the component’s own coil or element.
Cylinder 7: numbering follows the manufacturer’s layout — on most engines cylinder 1 is at the timing-belt or chain end. Check your engine’s diagram before replacing a part.
Can I keep driving with P0207?
The rule of thumb for this area (fuel & air metering): Usually drivable in the short term, with rougher running and worse fuel economy. Don’t leave mixture codes for weeks — a lean or rich engine damages the catalytic converter over time — and treat an injector code that comes with a misfire as urgent.
How P0207 breaks down
Powertrain. Engine, transmission, fuel and emissions — the codes behind the check engine lamp.
Generic code: defined by SAE, the same on every make.
Fuel & air metering.
The specific fault within this range.
Where to look: Fuel & air metering
The sensors the engine computer meters fuel from — mass air flow, manifold pressure, intake air and coolant temperature, throttle position, oxygen sensors and fuel pressure — the fuel trims it learns from them, and the injector, fuel-pump and turbocharger circuits.
Typical causes in this area
- Dirty or failed sensors — the mass air flow and oxygen sensors most often
- Vacuum and intake leaks
- Fuel delivery: pump, filter, pressure regulator
- Wiring and connectors
- Injector faults

Frequently asked
What does P0207 mean?
P0207 is a generic OBD2 powertrain code. It means “Injector Circuit/Open - Cylinder 7” — the same on every make and model, because the definition comes from the SAE J2012 standard rather than from the carmaker.

What causes P0207?
“Open” means the module found a break in the circuit — no current flowing where there should be. Check the connector (unplugged, corroded, a pushed-back pin), the wire, the fuse and the component’s own coil or element. Typical causes in this area: Dirty or failed sensors — the mass air flow and oxygen sensors most often; Vacuum and intake leaks; Fuel delivery: pump, filter, pressure regulator; Wiring and connectors; Injector faults.
How do I clear P0207?
Fix the cause first, then clear it with any OBD2 scanner or app. Once the fault is gone the car also clears it on its own: the check engine lamp goes off after the self-test passes on three drive cycles in a row, and the stored code ages out after about 40 warm-ups. Clearing without a repair only hides it for a while — and resets the readiness monitors an emissions inspection looks at.
Is P0207 the same on every car?
Yes. P0207 is a generic SAE J2012 code, so its definition is identical on every make and model. What differs is the cause behind it and the repair procedure, which depend on the engine — that’s why the assistant on this page asks for your car.
