What Does P0214 Mean?
This code indicates a malfunction in the cold start injector 2 circuit. The ECM has detected an electrical fault preventing the second cold start injector from operating correctly. This injector provides supplemental fuel enrichment during cold engine cranking. On engines with two cold start injectors (V-configuration), each bank has its own cold start injector.
Common Causes
35%
Defective cold start injector 2 with a stuck valve, clogged nozzle, or failed solenoid coil
30%
Damaged or corroded wiring in the cold start injector 2 circuit due to age and repeated thermal cycling
20%
Faulty cold start relay or thermal time switch not activating the injector 2 circuit at appropriate temperatures
15%
ECM driver failure for the cold start injector 2 output circuit
Diagnostic Steps
1
Step 1: Measure cold start injector 2 coil resistance at the connector. Compare to manufacturer specification (typically 3-6 ohms).
2
Step 2: Verify power supply to the cold start injector 2 during cranking with the engine below operating temperature.
3
Step 3: Check the thermal time switch function by measuring resistance at a known coolant temperature and comparing to specification.
4
Step 4: Test the cold start relay by applying 12V to the coil terminals and verifying the contacts close with proper resistance.
5
Step 5: Inspect all wiring, connectors, and ground paths in the cold start injector 2 circuit for deterioration.

The most common cause of P0214 (Cold Start Injector 2 Malfunction) is: Defective cold start injector 2 with a stuck valve, clogged nozzle, or failed solenoid coil
Typical repair costs for P0214 range from $120 to $400, depending on the vehicle, location, and whether you do it yourself or go to a shop.
A faulty cold start injector 2 causes difficult cold starting, particularly on the affected bank. This is an inconvenience rather than a safety concern, though repeated extended cranking can wear the starter motor.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0214 to identify the root cause.
