Internal Content
This Solution is relevant regardless of previous visits
and sensor replacements. At this time, multiple
sensor failures are not uncommon, regardless of
how new the sensor is. The same procedure should
be followed for every instance.
PLEASE NOTE: Instructions have been updated as of
20 June 2019. If diagnostics indicate that sensor
replacement is required, please follow FSB 284 - 068
Exhaust Particulate Sensor, Repair ( 2016 ) or FSB 284
- 069 ( 2017 ) Exhaust Particulate Sensor, Repair. An
eService case is not required
Precautions
1. The PM sensor is a smart sensor (12V supply and CAN lines) with
an orientation tab as seen below:

2. PM sensors need to be handled carefully. Dropping them most
likely results in permanent damage to the sensor. Keep cap on the
sensor until ready to install the sensor to avoid any contamination.
3. NEVER (DO NOT) apply anti-seize to install the PM sensor. If for
some reason someone applied it before this repair, thoroughly clean
the threads and sealing surfaces while replacing the sensor.
4. A removed PM sensor should be capped immediately (cap from
replacement sensor) and packaged carefully, if returning to warranty
or investigation purposes.
Repair
IMPORTANT:
• If a chassis arrives with a derate warning active, the PM sensor
is not the source of the derate and there is a separate existing
issue.
• Prior to installing a new sensor for any of the steps below,
gently shake the sensor and ensure it does not rattle. If noise is
heard, another sensor should be used.
1. Verify the chassis emissions level
- Details can be found in the Product Details box on the Product
tab in PTT as seen below:
• For US17+OBD16 (Common Rail Fuel System) Chassis setting
DTCs P24DA or P1031 ONLY:

e eased to add ess t s code.
• For US17+OBD16 Chassis setting any other codes for the PM
Sensor, Proceed with instructions below.
• For US14+OBD16 (Commonly 2017 model year): Proceed with
instructions below.
2. Check the DTC Status
Only troubleshoot PM sensor faults if the fault is Active or
Confirmed as shown below.
3. Follow the set of instructions for the relevant DTC(s):
• P1033, P1034, P24D0 or U02A3 fault codes (Confirmed or Active)
- These PM sensor fault codes require connections and wiring
harness checks for power supply and CAN communications. Repair
can be verified with just KEY ON as diagnostics run immediately.
- If wiring harness and connections check isolates the problem
to the sensor:
1. Remove the sensor from the exhaust.
2. Obtain a new sensor. Gently shake the new sensor to ensure
it does not rattle.
NOTE: A sensor that rattles should not be installed.
3. Install the new sensor.
4. Clear the DTCs and release the vehicle.
1. Replace the PM sensor with the latest part. Gently shake the
new sensor to ensure it does not rattle.
NOTE: A sensor that rattles should not be installed.
2. Update the Engine Control Module (EMS) software and
clear all codes.
3. Release the vehicle.
If the PM sensor is the current part number:
