P2214 code definition

Diagnostic trouble code P2214 is related to a secondary ignition coil fault on the 5th cylinder. It’s related engine misfire codes P0200 through P0212 and ignition coil codes P2200 through P2225.

What the P2214 code means

P2214 is a generic OBDII code that signals a problem with secondary ignition on the 5th cylinder. Many diagnostic systems use letters instead of numbers to indicate the location of the fault, so you may encounter an explanation including “Ignition Coil E”. DTC P2214 indicates that the powertrain control module (PCM) has detected a fault on the secondary ignition coil circuit. The code sets when the secondary ignition burn time is too short, incorrectly timed, or not present. It causes the Check Engine light to illuminate after a fault on a single trip. After three trips without a failure, the Check Engine light may go off, although the DTC will remain a stored, inactive code.

What causes the P2214 code?

There are a few causes of diagnostic trouble code P2214:

  • Automatic Shutdown (ASD) Relay circuit output is incorrect.
  • The control circuit for ignition coil number 5 is damaged or disconnected.
  • Ignition coil 5 control circuit wiring is shorted to ground.
  • The ignition coil on cylinder 5 is faulty, causing a misfire on cylinder 5.
  • The Powertrain Control Module (PCM) has an internal fault, causing the ignition failure on cylinder 5.

What are the symptoms of the P2214 code?

When DTC P2214 is present, the Check Engine light will be illuminated. Because the fault is on cylinder 5, there are usually several other cylinders that are operating properly. That can mask the performance-related symptoms you notice in some cases, however you may find a stumble or hesitation at idle and while driving. If DTC P2214 is present as a constant failure, symptoms may be more noticeable. You might notice a small increase in fuel consumption as well.

How does a mechanic diagnose the P2214 code?

A mechanic will use an OBD-II scan tool for preliminary testing to determine the cause of DTC P2214. They will check freeze frame data and operation while the engine is running to determine if the fault is ongoing or intermittent. A scan tool can be used to reset codes that are stored, then the mechanic will road test the vehicle to see if the code returns.

If the failure is ongoing or current, the code will return on the following trip. Then, the mechanic will trace the wiring associated with the ignition coil and ASD relay, checking for accurate resistance, making sure the connectors are properly seated and in good condition, and inspecting for wiring breaks, corrosion, and shorts. If no problems are found with wiring, injector coil 5 may be swapped with another cylinder to determine if it’s at fault. In rare cases, the failure can be traced back to the PCM where the circuit is not powered properly.

Common mistakes when diagnosing the P2214 code

Common problems in diagnosing code P2214 result because of an intermittent condition or due to skipping steps in diagnosis. Road testing to discover if the code will reoccur is important after every diagnostic step and attempted repair. Also, wiring problems are more commonly the cause than part failure. You may find that replacing the ignition coil without fully diagnosing the condition won’t resolve the symptom and the Check Engine light will come on again with the same fault code present. Connectors should be inspected thoroughly for corrosion and moisture as high resistance can result, causing DTC P2214.

How serious is the P2214 code?

In most cases, trouble code P2214 won’t make your vehicle undriveable. You may notice a lack of performance in some situations, especially if there are other DTCs present related to other cylinders. You may find your fuel consumption is increased as your engine tries to maintain its performance. If left uncorrected for some time, other issues can occur due to poor performance including emissions-related problems like catalytic converter performance and incorrect oxygen sensor readings. Sometimes, DTC P2214 the mechanic can clear the code with an OBD-II scan tool to reset the system and the engine may resume normal operation indefinitely.

What repairs can fix the P2214 code?

Common repairs for diagnostic trouble code P2214 can include:

  • Verify normal operating with a scan tool, then clear the code. The vehicle should then be road tested, and further repairs are required if the Check Engine light reappears due to DTC P2214.
  • Trace the wiring from the PCM to the ASD relay and cylinder 5 ignition coil. Repair any corrosion in connectors, and repair any bent or broken pins. If wiring has been rubbed through or is shorting to other wiring or the vehicle body, repair the wiring and retest.
  • Replace the Auto Shutdown relay if it’s determined to be faulty.
  • Replace the ignition coil on cylinder 5 with a new coil.
  • In rare cases, the PCM may need to be replaced due to an internal fault.

Additional comments for consideration regarding the P2214 code

DTC P2214 seems to be more prevalent in Dodge, Chrysler, and Jeep vehicles although not exclusively. The problems associated with DTC P2214 are usually on high-mileage vehicles because of their association with corrosion and wiring problems. Because of the nature of wiring problems, it’s often the case that DTC P2214 is an intermittent concern. It can take several attempts to recreate the problem, both through road tests and scanning with an OBD-II scan tool.
