P0362 means the powertrain control module has detected an open circuit in the primary (low-voltage) control side of ignition coil 'L', so it cannot reliably fire that coil. An open can exist in the coil winding, the control wire, or the connector between the coil and the module. The result is typically a misfire on the cylinder served by that coil.
The coil's internal primary winding or driver connection can fail open, making this the single most common cause of a primary control circuit open code.
A break, pinch, abrasion, or rodent damage in the low-voltage control wire between the coil and the PCM creates the open the code reports.
Terminal spread, corrosion, or poor pin contact at the coil harness connector interrupts the primary control signal without damaging the coil itself.
If the coil lacks battery voltage or a solid ground, the primary circuit cannot operate; this may be caused by a blown fuse, bad relay, or ground connection.
Although possible, a failed driver inside the PCM is uncommon for this code and should only be considered after the coil, wiring, connectors, and power/ground have been verified.
It is best to drive only minimally. A steady misfire can overheat and damage the catalytic converter, and unburned fuel can enter the exhaust.
Usually no. The failed component is most often the ignition coil, a connector, or wiring. PCM driver failure is genuinely rare for this code and should be confirmed by testing, not assumed.
It is the manufacturer-specific designation for a particular ignition coil or cylinder position in the firing order. The exact cylinder varies by engine design, so consult the service information for your vehicle.
You can clear it to verify whether the fault is continuous, but if the open still exists the code and misfire will return, and clearing it will not fix the underlying problem.
