Easy one-page printout for the garage or repair shop
This summary uses the existing diagnostic information shown in full below.
This code means that there's a problem with one of the car's ignition coils, which helps start the engine. It's like if one of the spark plugs that makes the car go isn't working right.
The engine control module (ECM) has detected an issue with the primary control circuit of the ignition coil labeled 'K'. This could be due to an open circuit or a malfunction in the coil itself.
The P0361 code is triggered when the ECM detects a fault in the ignition coil 'K' primary control circuit. This could be due to an open circuit, a short, or a failure within the coil. The ignition coil is responsible for converting the battery's voltage into a high voltage needed to create a spark at the spark plug.
• Engine misfire
• Rough idle
• Check Engine Light is on
• Faulty ignition coil K
• Open or shorted wiring in the ignition coil circuit
• Faulty ECM
ECM: Engine Control Module, the computer that controls engine functions.
Ignition Coil: A component that converts the battery's voltage to a higher voltage needed to create a spark.
• Use an OBD-II scanner to confirm the code.
• Inspect the ignition coil K and its wiring for damage.
• Test the ignition coil with a multimeter.
• Replace the faulty ignition coil K.
• Repair or replace damaged wiring in the ignition coil circuit.
• Replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Socket set
$100 - $300
Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect ignition components.
• Ensure proper maintenance of the vehicle's electrical system.
• Replace spark plugs and ignition coils as recommended by the manufacturer.
Engine Performance
• Do not ignore the Check Engine Light.
• Address misfires promptly to avoid further engine damage.
Check if your vehicle's powertrain warranty covers ignition system components.
Ignition coil issues are common in vehicles with higher mileage or those that have not had regular maintenance.
Moderate – Should be addressed soon to prevent engine performance issues.
Driving with a misfiring engine can lead to increased emissions and potential safety hazards.
• Engine running
• Warm engine
The ignition coil is typically located on top of the engine, above each cylinder.
Q: Can I drive with a P0361 code?
A: It's not recommended to drive for extended periods with this code, as it can cause engine damage.
Q: How do I know which coil is 'K'?
A: Refer to your vehicle's service manual or consult a professional mechanic.

Fitment Required · Vehicle-fitment part
Relevant when the fault points toward ignition-coil performance or cylinder-specific ignition issues.
Some ignition faults involve coil performance or cylinder-specific coil problems.
Match the coil to your engine and confirm the failed component before ordering.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
