P0361Ignition Coil K Primary Control Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0361 monitors the primary control circuit of ignition coil K – the line from the engine module to the coil or to its built-in output stage – for an open circuit or high resistance. Coil K usually serves cylinder 11, so the code only occurs on engines with at least 11 cylinders; in practice these are V12 or W12 engines. No manufacturer document available to us uses the code: GM goes up to coil H, Ford's descriptions end at coil J (P0360). CARB requires the ignition outputs to be monitored for open and short circuits. Ford's description of the same check for coils A to J shows how it works: it runs continuously between 200 and about 3,200 rpm at 11–16 V, judges either the current confirmation from the coil driver or the current and voltage at the driver output, and after a coil fault shuts off that cylinder's injector for 30 s at a time to protect the catalyst. Coil K's control circuit low and high are P2330 and P2331, its secondary circuit P2332.
- What you may notice
- Check engine light on
- Misfire and rough running on cylinder 11, often also P0311
- Loss of power, jerking under load
- Cylinder shut off (injection off), risk to the catalyst if driven on
- Likely causes
- LikelyIgnition coil K faulty (output stage in the coil or primary winding open)
- LikelyConnector at the coil corroded, wet or with a loose pin
- PossibleControl, supply or ground wire open or chafed
- RareDriver in the engine module faulty or software (permanent dwell)
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €60 – €350
