This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the fuel injectors on one side of the engine are not working properly because they are getting old.
The engine control module (ECM) has detected an issue with the long-term fuel trim adaptation for the injectors on Bank 2, indicating that the adjustments made to compensate for injector aging are not within expected parameters.
The P119E code indicates that the ECM has identified an inconsistency in the long-term fuel trim adaptation for the fuel injectors on Bank 2. This suggests that the injectors may be aging and not delivering fuel as expected, leading to an imbalance in the air-fuel mixture.
• Check Engine Light on
• Poor fuel economy
• Rough idle
• Engine misfires
• Aging or clogged fuel injectors on Bank 2
• Faulty oxygen sensor on Bank 2
• Vacuum leaks affecting Bank 2
• Faulty ECM
Fuel Trim: Adjustments made by the ECM to the air-fuel mixture.
Injector Aging: The process of fuel injectors wearing out over time, affecting performance.
• Use an OBD-II scanner to confirm the code.
• Inspect the fuel injectors on Bank 2 for clogs or wear.
• Check for vacuum leaks affecting Bank 2.
• Test the oxygen sensor on Bank 2.
• Replace or clean the fuel injectors on Bank 2.
• Repair any vacuum leaks.
• Replace the oxygen sensor on Bank 2 if faulty.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Fuel injector cleaner
• Vacuum leak tester
• Multimeter

Moderate
• BMW 3 Series
• Audi A4
• Mercedes-Benz C-Class
• Regularly clean fuel injectors.
• Perform routine engine maintenance.
• Check for vacuum leaks periodically.
Engine Performance
• Address the issue promptly to avoid further engine damage.
• Consult a professional mechanic if unsure about repairs.
Check with your vehicle manufacturer for specific warranty coverage related to fuel system components.
This code has become more common as vehicles age and fuel injectors wear out over time.
Moderate – It should be addressed soon to prevent potential engine performance issues.
Ignoring this code could lead to increased emissions and potential engine damage.
• Engine at operating temperature
• Vehicle in closed-loop mode
Bank 2 refers to the side of the engine opposite Bank 1, usually on V-type engines.
Q: Can I drive with a P119E code?
A: It's possible to drive short distances, but it is advisable to fix the issue soon to prevent engine damage.
Q: What happens if I ignore this code?
A: Ignoring the code can lead to poor fuel economy, increased emissions, and potential engine damage.

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.
