DTC Descriptor
DTC P2002 - Diesel Particulate Filter (DPF) Low Efficiency
Circuit/System Verification
1. Ignition ON.
2. Verify that DTCs P0100, P0101, P0102, P0103, P0651, P113C, P2032, P2033, P2084, P2085, P2470, P2228, P2229, P2452, P2453, P2454, P2455, or P2456 are not set
- If any of the DTCs are set
Refer to Diagnostic Trouble Code (DTC) List - Vehicle for further diagnosis.
- If none of the DTCs are set
3. Engine idling.
4. Verify the scan tool DPF differential pressure parameter is between 0–10 kPa (0–1.5 PSI).
- If not within the specified range
Refer to Circuit/System Testing.
- If within the specified range
5. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
6. Verify DTC P2002 does not set.
- If the DTC is set
Refer to Circuit/System Testing.
- If the DTC is not set
7. All OK.
Circuit/System Testing
1. Verify the integrity of the entire air induction system, exhaust system including all turbocharger components by inspecting for the conditions listed below:
- Damaged, loose, or improperly installed exhaust aftertreatent components
- Exhaust leaks, including loose or disconnected pipes and the mating surface area between the turbocharger and the exhaust manifold.
- If a condition exists
Repair as necessary.
- If no condition exist
2. Connect the exhaust port of the EN 23738–A vacuum gauge to port one (engine side) of the B154 Diesel Particulate Filter Exhaust Differential Pressure Sensor.
3. Ignition ON, using the EN 23738–A vacuum gauge, slowly apply pressure to the sensor while observing the DPF Differential Pressure parameter.
4. Verify the parameter increases smoothly without spikes or dropouts.
- If the parameter does not increase smoothly
Replace the B154 Diesel Particulate Filter Exhaust Differential Pressure Sensor.
- If the parameter increases smoothly
5. Replace the Diesel Particulate Filter.
