This summary uses the existing diagnostic information shown in full below.
This code means that there is a problem with the part of the car that makes the spark needed to start the engine. It's like when a flashlight doesn't work because the battery is too low.
The P1367 code indicates that the voltage in the ignition coil 'B' circuit is lower than expected, which can affect the engine's ability to start and run smoothly.
The ignition coil is responsible for converting the battery's low voltage to the high voltage needed to create a spark in the spark plugs. Code P1367 is triggered when the Engine Control Module (ECM) detects a low voltage condition in the primary or secondary circuit of ignition coil 'B'. This can be due to a fault in the coil itself, wiring issues, or a problem with the ECM.
• Engine misfires
• Poor engine performance
• Check Engine Light illuminated
• Faulty ignition coil 'B'
• Wiring issues or poor connection in the ignition coil circuit
• Faulty Engine Control Module (ECM)
Ignition Coil: A component that transforms the battery's voltage to a higher voltage to ignite the fuel-air mixture in the engine.
ECM: Engine Control Module, the computer that controls the engine's functions.
• Use an OBD-II scanner to verify the code.
• Inspect the ignition coil 'B' and its connections for damage or corrosion.
• Test the ignition coil 'B' using a multimeter to check for proper resistance.
• Replace the faulty ignition coil 'B'.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the Engine Control Module (ECM) if necessary.
• OBD-II Scanner
• Multimeter
• Basic hand tools

Moderate
• Honda Accord
• Ford F-150
• Toyota Camry
• Regularly inspect ignition system components.
• Ensure all electrical connections are secure and free of corrosion.
• Follow the manufacturer's maintenance schedule.
Engine Performance
• Address the issue promptly to avoid further engine damage.
• Consult a professional mechanic if unsure about the diagnosis.
Check if your vehicle's ignition system components are covered under the manufacturer's warranty.
This code is commonly associated with aging ignition systems and is often seen in vehicles with high mileage.
Moderate – While the vehicle may still run, it could lead to more serious engine problems if not addressed.
Driving with a misfiring engine can lead to increased emissions and may not comply with local environmental regulations.
• Engine at operating temperature
• Under load conditions such as acceleration
The ignition coil 'B' is typically located on the engine, near the spark plugs.
Q: Can I drive with a P1367 code?
A: It's not recommended to drive for extended periods with this code, as it can lead to further engine damage.
Q: How can I prevent ignition coil issues?
A: Regular maintenance and inspections can help prevent issues with the ignition coil.

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.
