UniversalCold Start Injector 1 Malfunction
The cold-start injector provides extra fuel during cold starting on vehicles equipped with this system. This code means the vehicle's control system has detected a malfunction associated with injector 1 or its operation. The exact monitoring method varies by vehicle. Cold starts may become difficult, though some vehicles may show no noticeable symptoms.
⚠️ Before You Begin (Safety First)
If the engine stalls or runs poorly enough to make the vehicle difficult to control, stop driving when safe and arrange an inspection. If you smell or see fuel, do not start or drive the vehicle; keep ignition sources away and seek professional help.
Common Symptoms
- Hard starting or extended cranking when the engine is cold if the injector is not providing the expected extra fuel.
- Rough running or stalling shortly after a cold start if cold-start fueling is affected.
- Little or no noticeable change in how the vehicle runs, particularly after the engine has warmed up.
Common Causes
- A fault within cold-start injector 1, such as an electrical or operating problem.
- Damaged, loose or corroded injector wiring or connector causing an unreliable connection.
- A fault in the injector control circuit or the vehicle's control system.
- A separate cold-start or fuel-delivery issue that requires diagnosis before attributing the code to a failed injector.
Diagnostic Steps
- Check the owner information and vehicle-specific service information to confirm whether the vehicle has a cold-start injector system.
- With the vehicle off and cool, look for visibly damaged, loose or corroded wiring and connectors associated with the injector. Do not disconnect fuel lines or probe wiring unless the service procedure and appropriate tools are available.
- If a scan tool is available, record the code and any freeze-frame information before clearing anything; this can help show whether the fault occurred during a cold start.
- Note whether starting or running symptoms occur only when cold, and share those observations with a technician.
- Arrange professional diagnosis if the code returns, starting problems persist, or there is any sign of a fuel leak.
When to Call a Professional
Confirm that the vehicle is equipped with a cold-start injector and check model-, year- and engine-specific service information. A technician can review scan data and freeze-frame information, inspect the injector wiring and connections, and test the injector and its control circuit using the vehicle's specified procedures. The code alone does not prove that the injector needs replacement.

Commonly Asked Questions
Does P0213 prove that cold-start injector 1 has failed?
No. The code identifies a detected malfunction associated with the injector system, but wiring, connections, control circuitry or another cold-start issue may be involved.
Can I drive with this code?
If the vehicle starts and runs normally, the code may not immediately prevent driving. Avoid driving if the engine stalls, runs unpredictably or there is a fuel smell or visible leak.
Why might the problem be noticeable only when the engine is cold?
The cold-start injector's role is associated with cold starting on vehicles equipped with one. A fault may therefore affect starting or early running more than operation after warm-up.
Is every vehicle equipped with a cold-start injector?
No. Equipment and diagnostic strategies vary. Confirm applicability using information for the vehicle's specific model, year and engine.
