Diagnostic Trouble Code P200200 - Diagnostic
Information; US14+OBD16 And Newer Emissions


US14+OBD2016 and newer vehicles are equipped with Particulate Matter
(PM) sensors. For these vehicles, the Engine Control Module (EMS) uses
the particulate matter sensor input to evaluate any damage in the Diesel
Particulate Filter (DPF). P2002 is an indication of possible DPF damage.
IMPORTANT
Premium Tech Tool Should NOT be used for diagnosis of P2002 on
vehicles with applicable emissions levels. The information below
should be followed instead.
For applicable vehicles with P200200 logged on a
DTC Readout:
Review the Detailed Status Information for the relevant code on the
DTC Readout.
• If the Confirmed DTC Value for P200200 is "False": DO NOT
diagnose this code. Proceed to diagnosis for any other relevant codes
present.
• If the Confirmed DTC Value for P200200 is "True": Proceed with the

1. Check for evidence of soot passing through the SCR by inspecting the
SCR outlet.
• If there is no evidence of soot passage through the SCR: Skip
to Step 3.
• If there is evidence of soot passage through the
SCR: Proceed to the next step (Step 2).
2. Inspect the DPF outlet for evidence of soot bypassing the filter, or
damage to the DPF.
• If there is no evidence of soot passage through the DPF and
no visible damage: Proceed to Step 3.
• If there is evidence of soot passage through the DPF, and/or
damage to the DPF is visible:​R
​ eplace the DPF.
3. If the aboves steps do not indicate any issues: Replace the PM
sensor.
• The PM sensor is the likely cause specifically when the SCR outlet
(near PM sensor) does not show any evidence of black soot.
• The DPF differential pressure (dP) sensor and Exhaust Gas
Recirculation (EGR) system have low to no inputs on the P2002
diagnostic routine for vehicles with these emissions levels.
This solution will be updated when further information is available
concerning Premium Tech Tool use for diagnosing this code.
