P0214
Cold Start Injector 2
Fuel injection
Generic OBD-II
High
What it means
P0214 means the ECM detected a fault with cold start injector 2 — an extra injector that adds fuel to help the engine start and idle when cold. It's typically the injector, its control circuit, or the wiring. The engine usually runs fine once warm; the fault shows up as hard cold starts, long cranking, or a rough idle just after starting on a cold morning.

Can I keep driving? Usually fine once warm — the fault mainly shows up as hard cold starts; the engine typically runs normally after it warms up.
Common symptoms
What you'll notice
- Check-engine light on
- Hard starting or long cranking when cold
- Rough idle or stalling right after a cold start
- Reduced performance until the engine warms up

- Faulty cold start injectorLikely
- Open or short in the cold start injector control circuitCommon
- Wiring or connector fault at the injectorCommon
- Faulty cold-start injector relay or driverLess often
- Faulty ECM/PCM (rare — rule out injector and wiring first)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data to confirm the fault set during a cold start.
- Inspect the cold start injector connector and wiring for damage or corrosion.
- Test the injector's resistance and check for its control signal during cranking.
- Confirm the injector actually delivers fuel on a cold start.
- Replace the cold start injector if it fails testing; repair wiring as needed. Clear and re-test.

Quick answers
Is it safe to drive with P0214?+
Usually yes once it's running — the problem is mainly hard cold starts. Fix it so cold starts stay reliable and to clear the light.
Can I just clear P0214?+
It returns on the next cold start if the injector or its circuit is faulty, so the underlying fault needs repairing first.
