P2314 Ignition Coil E Secondary Circuit

P2314 reports a fault on the high-voltage side of coil E, which only five-cylinder and larger engines have; it normally fires cylinder 5. The control line may be perfectly sound; what failed is the energy reaching the plug or the combustion that should follow. FCA is the documented user: on the 3.6-litre Pentastar V6 of 2015–2016 Caravan and Town & Country models it is coil 5 secondary circuit with insufficient ionization, one of six such codes that bulletin 18-069-16 tied to a faulty PCM in a short build window. GM, Ford and VW tables cover coil E only on the primary side (P2312, P2313, P0355). Practical checks are the plug of cylinder 5, the boot and a swap test with a neighbouring coil; if the code stays with the cylinder, look at the plug or the module.

Likely causes

Spark plug of cylinder 5 worn or fouled
Coil E secondary winding or boot damaged
PCM fault on FCA vans from the 2015 build window

Symptoms

  • Check engine light on
  • Misfire on cylinder 5
  • Rough idle, slight vibration
