P1367 · ChryslerIC Cylinder 7 Not Toggling After Enable

P1367 is a Chrysler-specific code that sets when the powertrain control module (PCM) commands the ignition coil for cylinder 7 to fire but does not see the expected electrical toggle on the coil control circuit. The PCM monitors the coil driver circuit for a voltage change after enable, and when that toggle is absent it flags the circuit as faulty and stores this code.

Symptoms you may notice

  • Illuminated check engine light, often with no other symptoms besides the warning light
  • Noticeable engine misfire or rough running, especially under load or at idle
  • Reduced engine power or limp mode in some Chrysler models
  • Shaking or vibration felt through the steering wheel and floorboard
  • Poor fuel economy and a strong raw fuel smell from the exhaust
  • Flashing check engine light if the misfire is severe enough to risk catalytic converter damage

Common causes, most likely first

  1. Failed ignition coil on cylinder 7, where the primary winding is open or shorted and cannot toggle
  2. Damaged or corroded wiring harness connector at the cylinder 7 coil
  3. Open or shorted coil control wire between the PCM and the cylinder 7 coil
  4. Faulty spark plug or spark plug tube filled with oil, causing the coil to fail under load
  5. PCM driver circuit failure for the cylinder 7 coil control
  6. Poor engine ground or chassis ground affecting coil operation
  7. Aftermarket or incorrect coil installed that does not meet Chrysler specifications

How to diagnose and fix it

  1. Scan all modules and record freeze-frame data to confirm the code is current and not a history code from a previous repair
  2. Inspect the cylinder 7 ignition coil connector and wiring for corrosion, chafing, or loose pins
  3. Swap the cylinder 7 coil with a known-good coil from another cylinder and see if the misfire and code follow the coil
  4. Measure resistance of the cylinder 7 coil primary and secondary windings and compare to Chrysler specifications
  5. Check for spark at cylinder 7 using a spark tester while cranking, and inspect the spark plug for fouling or damage
  6. Back-probe the coil control circuit at the PCM and verify the driver toggles when the engine is cranked
  7. Repair or replace the faulty coil, spark plug, or wiring as needed, then clear codes and verify the repair with a road test

Why cylinder 7 coil codes mislead

  • A coil that tests good with an ohmmeter can still fail to toggle under load, so a resistance check alone will not rule out a bad coil on this code.
  • Oil leaking into the spark plug tube from a failed valve cover gasket is a common hidden cause of cylinder 7 coil failure on Chrysler V8 engines.
  • The PCM may set P1367 without ever illuminating the check engine light if the misfire counter has not exceeded the threshold for a type A or B misfire.
  • A weak battery or poor ground can cause the PCM to misread coil toggle signals, so always verify battery voltage and ground integrity before condemning the PCM.
  • Aftermarket coils with incorrect internal resistance are a frequent cause of repeat P1367 codes even after replacement, so use OEM-spec parts.

Can I keep driving with P1367?

You can drive short distances to a repair shop if the engine runs smoothly and the check engine light is steady, but avoid heavy acceleration or towing. If the light is flashing or the engine is misfiring badly, stop driving to prevent catalytic converter damage.
