2024-2025 Jeep Compass/Renegade Fuel Injector Leakage TSB

Important Warnings for Owners

Owners of affected vehicles should be aware of specific advisories related to this issue:

• Market Specificity: This bulletin, TSB 09-016-25, applies exclusively to vehicles sold in the South American market. Owners in other regions may not be affected by this specific bulletin.
• Repair Procedure Caution: During the diagnostic leak test, technicians are strictly advised not to start the engine while inspecting the injectors with a videoscope. This is a critical safety measure to prevent damage or injury.
• Documentation: After the repair is completed, it is not necessary to send a DID-I or DID-A report.

Symptoms of Fuel Injector Leakage

Owners of 2024-2025 Jeep Compass and Renegade vehicles may notice several indicators if they are experiencing a 2024 Jeep Compass fuel injector leakage problem. The primary symptom is the illumination of the Malfunction Indicator Lamp (MIL) on the dashboard.

Additional symptoms include:

• The "injector light" illuminating on the Instrument Panel Cluster (IPC).
• Unstable engine idle.
• Abnormal noise emanating from the engine.

Fault Codes / DTCs

If a fuel injector leak is present, your vehicle's diagnostic system may store one or more of the following Diagnostic Trouble Codes (DTCs):

Code	Description
P0087	Fuel Rail Pressure Too Low - Bank 1
P0300	Multiple Cylinder Misfire
P0301	Cylinder 1 Misfire
P0302	Cylinder 2 Misfire
P0303	Cylinder 3 Misfire
P0304	Cylinder 4 Misfire
P006C	MAP - Turbocharger Inlet Pressure Correlation

Diagnosis / Trigger Conditions

Diagnosis for the 2024 Jeep Compass fuel injector leakage issue involves using a wiTECH scan tool to check for related DTCs and monitor engine parameters. Technicians will access the Engine Control Module (ECM) to view injection ramp pressure values in graphical mode. Key parameters to observe include engine speed, fuel rail pressure, desired fuel line pressure, and ignition deactivation time.

After warming the engine, the ignition is turned ON (without starting the engine) to observe the injection ramp pressure values for one minute. A significant drop in pressure indicates a leak. If a leak is suspected, spark plugs are removed, and a videoscope is used to visually inspect each cylinder for fuel leakage at the injector tips.

Repair Procedure Summary

The repair for fuel injector leakage, as outlined in TSB 09-016-25 and Rapid Service Update (RSU) 25-116, involves several steps:

1. Engine Warm-up: Start the engine and allow it to reach normal operating temperature.
2. wiTECH Connection: Connect the wiTECH diagnostic tool to the vehicle.
3. Parameter Monitoring: Access the injection ramp pressure values in the Engine Control Module (ECM) in graphical mode, monitoring parameters such as engine speed, fuel rail pressure, desired fuel line pressure, and ignition deactivation time.
4. Leak Test: Turn the engine OFF, switch the ignition to ON, and observe the injection ramp pressure values for one minute. If the graph indicates a pressure loss, proceed with further inspection.
5. Spark Plug Removal: With the engine OFF and at normal operating temperature, remove the spark plugs.
6. Videoscope Inspection: Insert a videoscope into each cylinder to inspect for fuel leakage. Crucially, the engine must not be started during this leak test.
7. Component Replacement: If a leak is confirmed, the fuel injectors and the fuel pipe (common rail/high-pressure pump) will be replaced. Detailed service procedures are available in DealerCONNECT/Service Library.
8. Reassembly and Clearance: Install the spark plugs and clear any stored DTCs.

Required Tools or Parts

For this repair, technicians will utilize specific diagnostic tools and replacement parts:

• Diagnostic Tool: wiTECH or an equivalent scan tool.
• Inspection Tool: Videoscope (no specific part number provided, indicated as NPN).
• Fuel Injector Supply Tube: Part numbers 68755134AA (NA market) or 7099032 (SA market), which replace part number 46341585.
