P0214 code definition
P0214 is a generic trouble code that indicates an issue with the cold start injector number 2.
This code may be seen with P0213, or misfire, rich, or lean condition codes.
What the P0214 code means
P0214 is a diagnostic code that is set once the ECM has detected an issue with out-of-range performance coming from the cold start injector 2. The ECM sets a diagnostic trouble code and sets a failsafe mode to prevent further damage to the engine. The failsafe mode will remain until the issue is resolved or normal range performance is found.
What causes the P0214 code?
P0214 can have a few typical causes:
- Open or shorted wiring harness
- Faulty cold start injector 2
- Electrical connection that is poor
What are the symptoms of the P0214 Code?
Symptoms are sometimes felt before the Check Engine Light is displayed on the dashboard. These symptoms include:
- The vehicle running poorly
- Decrease in fuel economy
- Hard-to-start conditions
- Lean or rich conditions
How does a mechanic diagnose the P0214 code?
A mechanic will always check for codes before anything else is done. Additional codes may include history codes or pending codes in addition to the current codes. Each code will have a freeze frame data that tells the condition the vehicle was in when the code was set.
The code will then be cleared and test driven to try to duplicate the issue.
Once the condition is duplicated a visual inspection will be performed for damaged wiring or leaks.
Finally, voltage will be checked at the cold start injector.
Common mistakes when diagnosing the P0214 code
Mistakes can be made if steps are not followed in the proper order, or if certain steps are not completed at all. The cold start fuel injector itself is the most common cause for this code, but everything must be tested before any components are replaced to avoid unnecessary repairs.
How serious is the P0214 code?
P0214 is a more uncommon code with fairly mild symptoms. Any codes with the engine that runs poorly should have care taken when they are driven for safe operation and should be replaced as soon as possible.
What repairs can fix the P214 code?
- Cold start injector 2 replacement
- Wiring harness repair or replacement
- Electrical connections fixed
Additional comments for consideration regarding the P0214 code
In some cases, fuel system cleaners can aid in the repair for P0214. These cleaners remove the varnish that builds up over time in the vehicles. This may help unclog fuel injectors and help in certain scenarios.
The cold start injector is an important feature in vehicles equipped with it. It allows the ECM to richen the air/fuel ratio in the intake to allow the fuel to combust easier in cold conditions. This allows the engine to heat up faster and run better when it is excessively cold outside.
