Cold Start Injector 2 Malfunction
The P0214 code indicates a malfunction in the cold start injector 2 circuit. This injector is used to enrich the fuel mixture during cold engine starts, improving drivability. The Powertrain Control Module (PCM) detects an electrical fault or performance issue with the injector, such as an open or short circuit, or a stuck injector. This can lead to hard starting, rough idle, and increased emissions.
01. Most Common Causes
- Faulty cold start injector 2
- Open or short circuit in the injector wiring
- Failed injector driver circuit in PCM
- Poor electrical connection at injector connector
02. Symptoms You Will Notice
- Hard starting in cold weather
- Rough idle or misfire during cold start
- Check Engine Light illuminated
- Possible black smoke from exhaust during cold start
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect injector 2 and its wiring for damage or corrosion.
Step 3: Test injector resistance with a multimeter (specs vary, typically 2-5 ohms).
Step 4: Check for power and ground at injector connector with key on.
Step 5: Perform a injector balance test or flow test if applicable.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances, especially in cold weather, as it can cause hard starting, poor fuel economy, and potential damage to the catalytic converter due to unburned fuel.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for parts and labor, depending on the cause. A new injector may cost $30-$80, and labor is usually 0.5-1 hour.
