P0213 OBD2 Code Guide
P0213 is a powertrain diagnostic trouble code. Use this hub to understand the plain meaning, the first checks to run, and which vehicle-specific guides may be more useful before replacing parts.
Cold Start Injector 1 Circuit Malfunction
P0213 means the engine control module detected an electrical or control fault related to cold start injector 1. This is not the same as a normal port injector misfire code: diagnosis should focus on whether the vehicle is equipped with a separate cold start injector, the injector power and control circuit, connector condition, cold-start enrichment command and fuel delivery during cold cranking. Do not replace regular injectors, pumps or the ECM until the cold-start circuit and application are confirmed.
Code verification standard
P0213 is published with SAE J2012 / ISO 15031-6 code structure plus OBD2 P0213 diagnostic context.
First checks
- - Read all stored and pending codes before clearing anything.
- - Save freeze-frame data so you know speed, load and temperature when the code set.
- - Inspect wiring, connectors, fuses, hoses and obvious leaks tied to the named system.
- - Compare live data against realistic values before buying sensors or modules.
- - Clear the code only after repair and complete a drive cycle to confirm it does not return.
P0213 Code: Meaning, Symptoms, Causes and Fixes
P0213 is an OBD2 diagnostic trouble code for a cold start injector 1 circuit or control fault. The highest-value checks are injector power, PCM command, connector tension, coolant temperature input, and wiring continuity before any injector or control module is replaced.
Severity and driving risk
Moderate. It can cause hard cold starts, rough idle after startup, rich/lean correction problems, and misfire-like symptoms when the engine is cold.
Usually short local driving is possible if the engine runs normally after warm-up, but diagnose before repeated cold-start failures, fuel smell, stalling, or a flashing check engine light.
First checks before parts
- - Save freeze-frame data and note coolant temperature when P0213 set.
- - Check the cold start injector fuse/feed, ground or PCM command, and connector pin tension.
- - Compare coolant temperature sensor data to ambient temperature after the car sits overnight.
- - Measure injector coil resistance and compare it with service-data expectations.
- - Inspect harness sections near hot engine areas for brittle insulation or rub-through.
- - Clear the code only after repair and confirm the cold-start monitor does not reset P0213.
Do not replace first
Do not replace the injector, PCM, or coolant temperature sensor first without proving power, ground/command, resistance, and wiring integrity.
Cost level
Low to moderate when it is wiring, connector, fuse, or injector related; high only if module diagnosis and programming are truly required.
P0213 diagnostic path
- 1Confirm P0213 and save freeze-frame data, especially coolant temperature, intake temperature, cranking state and battery voltage.
- 2Verify from service information whether the vehicle uses a separate cold start injector or an equivalent cold-start enrichment circuit before testing parts.
- 3Inspect the cold start injector connector and nearby harness for loose terminals, corrosion, oil intrusion, heat damage or previous repair splices.
- 4Check the injector power feed and ECM control side with the correct wiring diagram; avoid universal resistance or voltage assumptions.
- 5Compare cold-start command, injector activation and fuel delivery behavior with scan-tool output tests or manufacturer-approved test methods where available.
- 6Repair the verified connector, wiring, injector or control fault, then retest after a true cold soak to confirm P0213 does not return.
Verify before repair
- - Repair corroded, loose or damaged cold start injector connector terminals.
- - Repair open, shorted or high-resistance wiring in the cold-start injector circuit.
- - Replace cold start injector 1 only after circuit command and application checks support it.
- - Correct fuel delivery issues that affect cold cranking after confirming the injector circuit is not the primary fault.
