Cold Start Injector 2
Diagnostic trouble code P0214 indicates that the powertrain control module (PCM) has detected an electrical circuit malfunction involving cold start injector 2. The PCM sets this code when the voltage or resistance in this specific injector circuit falls outside of the expected manufacturer specifications during a cold engine start.
While the vehicle will typically still run once warmed up, this issue can cause significant difficulty starting the engine in cold weather. It should be diagnosed soon to prevent excessive wear on the starter and battery.
Common symptoms
- Illuminated Check Engine Light
- Extended cranking time when the engine is cold
- Engine hesitates or stumbles during cold starts
- Rough idle until the engine reaches operating temperature
- Poor overall engine performance when cold
Likely causes
- Faulty cold start injector 2
- Corroded or damaged electrical connector at the injector
- Open or shorted wiring in the cold start injector circuit
- Faulty Engine Coolant Temperature (ECT) sensor providing inaccurate data
- Failed powertrain control module (PCM) (rare)
What to check before replacing parts
Visually inspect the wiring and connector for cold start injector 2.
Look for: Look for frayed wires, melted insulation, or corroded pins that could cause an open or short circuit.
Measure the internal resistance of cold start injector 2 using a multimeter.
Look for: Compare the resistance reading in ohms to the manufacturer's specification; an infinite reading indicates an open internal coil.
Check for proper voltage and ground at the injector connector during a cold crank.
Look for: A lack of 12-volt power or a missing ground pulse from the PCM indicates a wiring issue or a faulty control module.
Verify the Engine Coolant Temperature (ECT) sensor data using a scan tool.
Look for: The ECT reading should match the ambient temperature when the engine is cold; an inaccurately high reading will prevent the PCM from commanding the cold start injector.
Perform a noid light test on the cold start injector harness.
Look for: The noid light should flash during cold engine cranking, confirming the PCM is actively pulsing the injector circuit.
