This summary uses the existing diagnostic information shown in full below.
This code means that there's a problem with the way the car is checking the spark in cylinder 4. It's like the car's computer is not getting the right signal from that part of the engine.
The vehicle's engine control module (ECM) is not receiving the expected signal from the ionic current control module for ignition cylinder 4, indicating a low voltage or communication issue.
The P130E code is triggered when the ECM detects a lower than expected signal from the ionic current control module related to ignition cylinder 4. This module is responsible for monitoring the combustion quality and detecting misfires by measuring the ionic current in the combustion chamber. A low signal may indicate issues with the module, wiring, or ignition components.
• Check Engine Light illuminated
• Rough engine idle
• Reduced engine performance
• Faulty ionic current control module
• Wiring issues or poor connections
• Faulty ignition coil for cylinder 4
ECM: Engine Control Module
Ionic Current: A measure of the electrical charge in the combustion chamber used to monitor combustion quality.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for cylinder 4's ignition system.
• Test the ionic current control module and ignition coil for cylinder 4.
• Repair or replace damaged wiring or connectors.
• Replace the ionic current control module if faulty.
• Replace the ignition coil for cylinder 4 if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• BMW 3 Series
• BMW 5 Series
• BMW X5
• Regular maintenance and inspection of ignition components.
• Ensure all electrical connections are secure and free of corrosion.
• Use high-quality replacement parts.
Engine Performance
• Have the vehicle inspected by a professional mechanic.
• Avoid driving the vehicle if the engine is running rough to prevent further damage.
Check with the vehicle manufacturer for warranty coverage on ignition components.
This code is commonly associated with BMW vehicles and may indicate issues with the advanced ignition monitoring systems used in these cars.
Moderate – Addressing this issue promptly can prevent further engine damage.
Driving with an ignition system fault can lead to increased emissions and potential engine damage.
• Engine running
• Vehicle at operating temperature
The ionic current control module is typically located near the ignition coils on the engine.
Q: Can I drive with a P130E code?
A: It's not recommended to drive with this code as it can lead to engine misfires and potential damage.
Q: How can I prevent this code from appearing again?
A: Regular maintenance and using quality parts can help prevent this issue.
