Code details

Generic OBD-II · P0

System: Injector
Code type: Generic (SAE / ISO controlled)

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not replace cold start injector 2 before verifying cold-start enable conditions and circuit integrity.

Symptoms of P0214

Check-engine light, often with a misfire feel from one cylinder.
Rough idle, hesitation, or a slight loss of power.
Higher fuel use, or in some cases a fuel smell.

Common causes of P0214

A stuck, leaking, clogged, or electrically failed injector.
Injector wiring, connector, or driver-circuit faults.
Low fuel pressure or contamination affecting injector behaviour.

Useful checks before replacing parts

Check cold start injector 2 feed voltage, control command, resistance, connector fit, and fuel supply during valid cold-start conditions.
Compare coolant temperature, intake temperature, start enrichment, fuel pressure, and cranking behavior when the fault sets.
Inspect wiring, connector corrosion, injector leakage, spray or flow where testable, and related cold-start or temperature codes.
