P1362 · ChryslerIC Cylinder 2 Not Toggling After Enable

P1362 on Chrysler vehicles means the powertrain control module (PCM) commanded the ignition coil for cylinder 2 to fire, but the coil's feedback circuit never showed the expected voltage toggle, so the PCM cannot confirm the coil actually energized. The engine may run rough or set a misfire code, but often the only clue is the stored P1362 itself.

Symptoms you may notice

  • Check engine light illuminated, often with no other noticeable symptoms
  • Rough idle or a noticeable shake that feels like a misfire on one cylinder
  • Hesitation or stumble during acceleration, especially under load
  • Slightly reduced fuel economy if the misfire is persistent
  • A flashing check engine light in severe cases where the misfire could damage the catalytic converter

Common causes, most likely first

  1. Failed ignition coil on cylinder 2 (open or shorted primary winding)
  2. Damaged or corroded coil connector or harness wiring at cylinder 2
  3. Open or shorted feedback circuit between the coil and the PCM
  4. Faulty spark plug or excessive plug gap causing the coil to work harder and fail the toggle test
  5. PCM driver circuit fault for the cylinder 2 coil control
  6. Poor engine ground or corroded ground strap affecting coil operation

How to diagnose and fix it

  1. Scan all modules and record freeze-frame data to confirm P1362 is current and not a history code
  2. Inspect the cylinder 2 ignition coil connector and harness for corrosion, chafing, or loose pins
  3. Swap the cylinder 2 coil with a known-good coil from another cylinder and see if the code follows the coil
  4. Measure primary and secondary resistance of the cylinder 2 coil and compare with the manufacturer's specification
  5. Check the feedback circuit for continuity and shorts between the coil connector and the PCM
  6. Inspect and replace the spark plug on cylinder 2 if worn or fouled, then clear codes and retest
  7. If wiring and coil test good, perform a PCM driver test or substitute a known-good PCM to rule out an internal driver fault

Why cylinder 2 coil codes mislead

  • A coil that fires fine at idle can still fail the toggle test under load, so a simple spark check does not rule out P1362.
  • The feedback circuit is a low-current signal wire, and a single chafed spot against the valve cover can set this code without any visible coil damage.
  • Technicians often replace the coil first and later find the real fault is a corroded ground strap or a pushed-out terminal in the connector.
  • P1362 can be stored intermittently by a coil that only fails when hot, so always test after a road test that brings the engine to operating temperature.
  • A weak spark plug on cylinder 2 can cause the coil to draw abnormal current and trigger the toggle fault even though the coil itself is healthy.

Can I keep driving with P1362?

You can usually drive short distances to a shop, but avoid heavy acceleration and long trips until the fault is repaired. If the check engine light flashes, stop driving and have the vehicle towed because a persistent misfire can destroy the catalytic converter.
