P0213 Cold Start Injector 1 Malfunction
OBD-II Trouble Code Technical Description
Cold Start Injector 1 Malfunction
What does that mean?
This generic powertrain diagnostic trouble code (DTC) typically applies to OBD-II equipped vehicles that have a cold start injector. Makes of vehicles may include but are not limited to Ford, Dodge, GMC, Chevy, VW, Volvo, Jaguar, etc.
When a P0213 is stored in your OBD-II vehicle, it means that the powertrain control module (PCM) has detected an abnormality in the primary (1) cold start injector.
These types of injectors are primarily used in vehicles with diesel engines but I have personally seen cases where they were used in gasoline engine applications as well.
Typically, the cold start injector/s are placed in a centrally located position so that all cylinders of the engine can benefit from a "shot" of fuel delivered during cold start conditions. Some vehicles utilize multiple (I have never seen more than two) cold start injectors placed in strategic locations in the engine intake. Others use a single injector which is usually placed near the throttle plate opening or intake air inlet pipe.
By monitoring engine temperature and intake air temperature, the PCM is able to determine when the cold start injector must be initiated. In most vehicles, the cold start injector circuit is evaluated by the PCM in order to ensure that it is operating as intended. If the PCM detects an abnormal level of resistance on the circuit (accompanied by decreased voltage as a result), a code P0213 will be stored and a malfunction indicator lamp (MIL) may be illuminated. Some vehicles may require multiple ignition cycles with a failure for a MIL to be illuminated.
Here is an example of a cold start injector:
Code Severity & Symptoms
Cold start injector failure can make starting the engine in adverse weather conditions more difficult than usual. A code P0213 should be addressed with some degree of urgency.
Symptoms of a P0213 trouble code may include:
Delayed engine start- up (especially when cold) No symptoms may be exhibited during warm weather Engine coolant temperature or intake air temperature codes may also be exhibited Lean exhaust codes Misfire codes may also be storedCauses Of This DTC Code
Possible causes for this code may include:
Defective cold start injector Faulty engine coolant temperature sensor or circuit Bad intake air temperature sensor or circuit Shorted or open wiring in the cold start injector circuitDiagnostic and Repair Procedures
A diagnostic scanner, a digital volt/ohmmeter (DVOM), and a reliable vehicle information source are some of the tools which I will require to diagnose a code P0213.
If engine coolant temperature codes or intake air temperature codes are present, diagnose and repair those prior to diagnosing a code P0213.
Visual Inspection
A visual inspection of system related wiring and connectors should be performed as a starting point for your diagnosis. Rodent damaged wiring is not uncommon particularly in cold climates.
Next, I would connect the scanner to the vehicle diagnostic connector and retrieve all stored codes and freeze frame data. I like to write this information down as it has proven helpful as the diagnostic process unfolds. Clear the codes, allow the vehicle to reach a "cold start" condition according to manufacturer's specifications, and test-drive the vehicle to see if the code P0213 is reset.
If the P0213 is not immediately reset, continue to operate the vehicle normally until the PCM enters readiness mode or the code is reset. If readiness mode is entered, the problem has been rectified. If the code is reset, a problem still exists.
Step-by-step diagnosis
If the code is immediately reset, you can begin by testing the cold start injecRead: 45
