This summary uses the existing diagnostic information shown in full below.
This code means that something is wrong with the part of the car that helps give fuel to one of the engine's cylinders. It's like if one of the straws you use to drink your soda is pinched, and not enough soda is getting through.
The engine control module (ECM) has detected a low voltage condition in the circuit that controls the low side of the high pressure fuel injector for cylinder 11.
P3141 indicates that the ECM has identified an issue with the low side circuit of the high pressure injector for cylinder 11. This could be due to a wiring problem, a faulty injector, or an issue with the ECM itself. The low side circuit is responsible for grounding the injector, allowing it to operate correctly.
• Engine misfire
• Poor fuel economy
• Check engine light illuminated
• Faulty fuel injector
• Damaged wiring or connectors
• Faulty engine control module (ECM)
ECM: Engine Control Module, the computer that controls engine functions.
Injector: A device that sprays fuel into the engine's cylinders.
• Perform a visual inspection of the wiring and connectors for damage.
• Use a multimeter to check for continuity and proper voltage in the injector circuit.
• Test the injector for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the faulty fuel injector.
• Reprogram or replace the ECM if necessary.
• Multimeter
• OBD-II scanner
• Basic hand tools

Moderate
• Audi A8
• BMW 7 Series
• Mercedes-Benz S-Class
• Regular maintenance checks
• Ensure proper fuel quality
• Inspect wiring and connectors periodically
Engine Performance
• Avoid driving the vehicle until the issue is resolved to prevent further damage.
• Consult with a professional mechanic for accurate diagnosis and repair.
Check with your vehicle manufacturer to see if the repair is covered under warranty.
This code is commonly associated with vehicles that have high mileage or have been exposed to harsh driving conditions.
High – This issue can lead to engine performance problems and should be addressed promptly.
Driving with a malfunctioning injector can lead to increased emissions and may not comply with local regulations.
• Engine at operating temperature
• Vehicle in idle or under load
The high pressure injector for cylinder 11 is located on the engine, typically near the intake manifold.
Q: Can I drive with a P3141 code?
A: It's not recommended as it can cause further engine damage and poor performance.
Q: How can I prevent injector issues?
A: Regular maintenance and using high-quality fuel can help prevent injector problems.
