Cold Start Injector 2 Malfunction
What does P0214 mean?
The P0214 code means the vehicle's onboard diagnostic system has detected: Cold Start Injector 2 Malfunction. This is a moderate severity code.
Common Symptoms
- Check Engine Light on
- Difficult cold starts, especially in freezing weather
- Rough idle during initial warm-up
- Extended cranking before engine catches
- Increased cold-start emissions
Probable Causes (Ranked by Likelihood)
- Failed cold start injector 2 Very High
- Clogged injector nozzle from carbon or fuel deposits High
- Wiring issue in the injector 2 circuit Moderate
- Faulty cold start relay or thermal time switch Moderate
- PCM driver circuit failure Low
Step-by-Step Diagnostic Procedure
-
Verify cold start injector 2 receives power during cold cranking by checking for voltage at the connector.
-
Measure injector resistance (typically 2-6 ohms). Compare to specifications.
-
Test the thermal time switch or relay that controls cold start injector activation.
-
Remove the injector and check the spray pattern for even distribution.
-
Inspect wiring and connector for damage, corrosion, or breaks.
Frequently Asked Questions
Can I drive with code P0214?
Yes, you can drive short distances. The engine will start and run once warmed up, but cold starts may require extended cranking or multiple attempts, especially in cold weather.
Why do some vehicles have two cold start injectors?
Vehicles with V6 or V8 engines may have two cold start injectors -- one for each bank -- to ensure even fuel distribution during cold starts. P0213 is injector 1 and P0214 is injector 2.
Can I clean a cold start injector?
You can try cleaning the injector with fuel injector cleaner or by soaking the nozzle in a cleaning solution. However, if the internal coil has failed (high or infinite resistance), cleaning will not help and the injector must be replaced.
