Cold Start Injector 1 Malfunction
What does P0213 mean?
The P0213 code means the vehicle's onboard diagnostic system has detected: Cold Start Injector 1 Malfunction. This is a moderate severity code.
Common Symptoms
- Check Engine Light on
- Hard starting in cold weather
- Rough idle during cold start that improves as engine warms
- Excessive cranking time before engine starts
- Higher emissions during cold operation
Probable Causes (Ranked by Likelihood)
- Failed cold start injector Very High
- Clogged cold start injector nozzle High
- Wiring issue in the cold start injector circuit Moderate
- Faulty cold start injector relay or timer Moderate
- PCM control circuit failure Low
Step-by-Step Diagnostic Procedure
-
Check if the cold start injector is receiving power and ground when the engine is cold. The injector should activate during cold cranking (below approximately 95 degrees F).
-
Measure cold start injector resistance (typically 2-6 ohms). Out of range indicates a failed injector.
-
Check the cold start injector relay or timer switch. Verify it energizes when the engine temperature is below the activation threshold.
-
Inspect the injector for clogging by removing it and checking spray pattern. It should produce a fine, even mist.
-
Check the wiring from the PCM to the cold start injector for continuity and proper voltage.
Frequently Asked Questions
Can I drive with code P0213?
Yes, you can drive short distances. The cold start injector only operates during cold starts. Once the engine is warmed up, it functions normally. However, cold-start performance will be poor.
What is a cold start injector?
A cold start injector is an extra injector that provides additional fuel during cold engine cranking to help the engine start more easily. It is found on older fuel injection systems and is activated by a thermal time switch or the PCM when the engine is cold.
Do modern vehicles have cold start injectors?
Most modern vehicles (2010+) do not have a separate cold start injector. Instead, the PCM increases the pulse width of the regular fuel injectors during cold starts. P0213 is primarily seen on older vehicles.
