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.
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.
P0214 can have a few typical causes:
Symptoms are sometimes felt before the Check Engine Light is displayed on the dashboard. These symptoms include:
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 your 2009 Saturn Vue 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.
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.
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.
In some cases, fuel system cleaners can aid in the repair for P0214. These cleaners remove the varnish that builds up over time in your 2009 Saturn Vue s. This may help unclog fuel injectors and help in certain scenarios.
The cold start injector is an important feature in 2009 Saturn Vue s 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.
