Cold Start Injector 1 Malfunction
The P0213 code indicates a malfunction in the cold start injector circuit for injector 1. This injector is used to enrich the fuel mixture during cold engine starts. The Powertrain Control Module (PCM) detects an abnormal voltage or resistance in the injector circuit, often due to a faulty injector, wiring issues, or a defective PCM. This can cause hard starting, rough idle, and increased emissions.
01. Most Common Causes
- Faulty cold start injector
- Open or shorted wiring in injector circuit
- Poor electrical connection at injector or PCM
- Defective PCM
02. Symptoms You Will Notice
- Hard starting in cold conditions
- Rough idle or misfire during warm-up
- Check Engine Light illuminated
- Poor fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect the cold start injector and wiring for damage or corrosion.
Step 3: Test injector resistance with a multimeter (specs: 2-5 ohms).
Step 4: Check for voltage at injector connector with key on (should be battery voltage).
Step 5: Use a noid light to test injector pulse during cold start.
Step 6: If all tests pass, suspect a PCM issue and perform further diagnostics.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive with this code, especially in cold weather, as it can cause hard starting and poor engine performance. Continued driving may lead to increased emissions and potential damage to the catalytic converter.
How much does it cost to fix?▼
The cost to fix a P0213 code typically ranges from $50 to $150, including parts and labor. The cold start injector itself costs around $30-$80, and labor is usually 0.5-1 hour.
