This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is not getting a strong enough signal from the part of the engine that checks how well the fuel is burning on one side of the engine.
The P1368 code is triggered when the Engine Control Module (ECM) detects a low ionic current signal from the ignition system on Bank 2, indicating potential issues with combustion quality monitoring.
The ionic current monitoring system is part of the ignition system that checks the quality of combustion in the engine cylinders. Bank 2 refers to the side of the engine opposite to Bank 1. A low signal indicates that the ionic current is weaker than expected, which could affect engine performance and emissions.
• Check Engine Light illuminated
• Rough engine idle
• Poor fuel economy
• Faulty ignition coil
• Damaged spark plug
• Wiring issues in the ignition system
Ionic Current: An electrical current used to monitor combustion quality in the engine.
Bank 2: The side of the engine opposite to Bank 1, typically the side without cylinder 1.
• Use an OBD-II scanner to confirm the code.
• Inspect ignition coils and spark plugs on Bank 2.
• Check wiring and connections for damage or corrosion.
• Replace faulty ignition coils.
• Replace damaged spark plugs.
• Repair or replace damaged wiring.
• OBD-II scanner
• Multimeter
• Socket set

Moderate
• BMW 3 Series
• BMW 5 Series
• BMW X5
• Regular maintenance of ignition system components.
• Use high-quality fuel.
• Check and replace spark plugs at recommended intervals.
Engine Performance
• Address the issue promptly to avoid further engine damage.
• Consult a professional mechanic if unsure about repairs.
Check with the vehicle manufacturer for specific warranty coverage related to ignition system components.
This code is commonly associated with ignition system issues in vehicles with advanced combustion monitoring systems.
Moderate – It should be addressed soon to maintain engine performance and efficiency.
Ignoring this code may lead to increased emissions and reduced fuel efficiency, which could be subject to legal regulations.
• Engine at operating temperature
• Vehicle in park or neutral
The ignition coils and spark plugs are located on the engine, typically accessible from the top of the engine bay.
Q: Can I drive with a P1368 code?
A: It's possible to drive, but it's not recommended as it may lead to poor engine performance and increased emissions.
Q: How can I prevent a P1368 code?
A: Regular maintenance of the ignition system and using quality fuel can help prevent this code.
