Guide To P0214 OBD Error Code Solutions

<<See All OBD Codes

The P0214 is a generic fault code which would indicate that there is an issue with the cold start injector number 2. This fault code can be seen with P0213, or misfire, rich. or lean condition codes.

There are some fuel systems which would use separate injector so that it can provide additional fuel during cold starting. This injector is appropriately called a cold start injector. The design of the cold injector is just like a regular fuel injector. The cold start injector can be turned on with the help of a cold start injector switch and the powertrain control module. Now when the injector would be turned on, a solenoid which is present inside would lift a valve off its seat, thus allowing the injector to spray fuel. The fault code P0214 refers to the 2^nd of two cold injectors.

What causes this problem with the Cold Start Injector 2 Malfunction?

• There can be some defects in the cold start injector
• Some faults in the engine coolant temperature sensor or circuit
• The intake air temperature sensor or circuit would turn out to be bad
• There would be shorted or open wiring in the cold start injector circuit
• Poor electrical connection
• Defaults in the powertrain control module
• Faults in the cold start injector 2 switch

You might be thinking that how would you diagnose these problems? We at Parts Avatar Canada would help you diagnose the major symptoms easily.

Common Symptoms

• There can be a delay in the engine start- up
• No symptoms might be exhibited during warm weather
• Engine coolant temperature or intake air temperature codes might be exhibited
• There can be some lean exhaust codes
• Some misfire codes can also get stored

We have listed out some ways which would help you to correct the occurrence of OBD Code P0214. They are mentioned here as follows:

• You must replace the cold start injector 2
• Wiring harness should be repaired or replaced
• The electrical connections should be carefully fixed

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of fuel injector harness, body control module, fuel injection kit and many more. Now all your problems would vanish within no time.

Here are some steps which you must follow to diagnose the P0214 fault code:

• There are a lot of automotive fuel injectors which are actuated via a locking two-wire electrical connector
• They are provided with a constant supply of voltage which is comparable to that of the battery, through a fused power wire
• The circuit is completed by the second wire which is grounded by the fuel injector driver in the Pcm (Or Other Suitable Controller) in the form of regulated pulses
• Now when the circuit is actually completed, then the next step is to activate the fuel injector and later spray of fuel is injected in the individual cylinders or the throttle body. You can successfully diagnose this code storing condition with the help of a scanner, a digital volt/ohmmeter, a suitable ‘node lamp’ as well as a manufacturer’s service manual. You must begin your diagnosis by visually inspecting all the wirings as well as connectors
• You can always repair or replace the damaged, disconnected, shorted, or corroded wiring, connectors, and other components as per the need
• If you want to ensure success, then you must retest the system once all the repairs have been completed. If you find out that the system wiring, connectors and various other components are in good working order, then you must connect the scanner or the code reader to the diagnostic connector and record all the stored codes as well as freeze frame data
• All this information would prove to be extremely helpful while diagnosing the intermittent conditions that have contributed to this code being stored
• Now once the codes have been cleared up, then you should operate the vehicle to see if the code returns
• If the code has failed to return immediately, then you surely have an intermittent condition
• It can be quite challenging to diagnose an intermittent condition and in some extreme case it may have to be allowed to worsen before the correct diagnosis can be actually made. You should use a digital volt/ohmmeter to test the constant power supply to the particular fuel injector group
• If you find out that no battery voltage has been detected at the fuel injector group connector, then you must check the system fuses as well as relays
• All the faulty components should be repaired as per the requirement, then clear the codes and retest the system to ensure that the repair was successful
• The fuses which are under load should be carefully tested
• The fuses that appear to be working in normal condition with the key on and the engine off can fail when the engine is cranked
• If there are poor connections in the fuse panel, then it can also contribute to this condition
• If the fuses as well as relays are intact, then you must disconnect the connector from the powertrain control module and should perform a continuity and resistance test on all the related circuits
• Make sure that you repair or replace the open or shorted circuits, connectors or other components as per the requirement
• All the codes should be cleared up and then the vehicle should be taken out for a test drive to ensure a successful repair
• If the power supply is present at the fuel injector connector or the harness connector, then you should use a “noid lamp” to check for a ground pulse from the powertrain control module
• If you find out that no ground pulse has been actually detected, then the electrical connector from the powertrain control module should be disconnected and a continuity and resistance test should be performed on all the circuits
• Then you should repair the open or shorted electrical wiring, connectors, or components as required. Then the codes should be cleared up and retest the system
• If all the circuits appear to be intact, then you must suspect the faulty injector driver in the powertrain control module
• The failure of the powertrain control module is rare and its replacement would require the reprogramming of one or more controllers. If a constant power supply and ground pulse are present, then you should use a listening device to determine whether the injector is being activated

Common Mistakes When Diagnosing The P0214 Code

If you will not follow the steps in proper order, then due to that a lot of mistakes can occur. Some mistakes can also happen if certain steps are not completed at all. The most common cause behind triggering up of this code is the cold start fuel injector, that’s the reason why make sure that you test everything before you replace any components to avoid unnecessary repairs.
