** SOLUTION **
Cause
With the implementation of US14+OBD16 Emissions controls (Model Year 2017), a
new sensor was required to monitor particulate matter (PM)—soot—levels in exhaust
that has already passed through the Emissions Aftertreatment System. Excessive
particulate levels at this stage can indicate a damaged or failed Diesel Particulate Filter
(DPF). The PM sensor's only purpose is monitoring and is not used in any EATS
(regeneration and NOx conversion) functions. Codes set by the sensor will not
affect performance or cause a Derate.
The PM sensor is located after the exhaust muffler (SCR) and very close to NOx sensor
after the SCR (NOx2).
Solution
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:
Installation torque of 50 Nm +/- 5
Nm
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:
- Software improvements have been released to address this code. Refer to CBR Solution
K00527512.
• 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.
- If any of the above faults are present:
1. Ensure that there is no damage to the sections of the DPF the wiring harness that the
PM sensor wires run through.
2. Disconnect the PM sensor connector and the FCEIC connector.
3. Ensure there is no damage to the pins in either connector, and check that there is
good pin tension (drag test).
4. Thoroughly clean both connectors and reconnect them.
5. Test drive the vehicle to ensure the issue does not return.
• P1031 and P24DA (both fault codes and only these fault codes Active)
- If the vehicle has PM sensor part number 22733524 or older:
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:
1. Verify that the EMS software is current.
2. Remove the sensor from the exhaust.
3. Obtain a new sensor. Gently shake the new sensor to ensure it does not rattle.
NOTE: A sensor that rattles should not be installed.
4. Install the new sensor.
5. Clear the DTCs and release the vehicle.
• All other PM sensor fault codes (Confirmed or Active)
P24B3, P24AF, P2AB0, P24B1, P24B0, P24DA, P24B7, P24B5, P24D1, P24FC, P24AE,
P24B4, and P1032. (Highlighted are common faults).
1. Verify that the EMS software is current.
2. Remove the sensor from the exhaust.
3. Obtain a new sensor. Gently shake the new sensor to ensure it does not rattle.
NOTE: A sensor that rattles should not be installed.
4. Install the new sensor.
5. Clear the DTCs and release the vehicle.
Internal comments (BO)
• If a Diagnostic Monitor fails, DO NOT PERFORM A REGEN . Perform the
following steps:
1. Turn the vehicle's ignition OFF.
2. Restart Premium Tech Tool.
3. Reconnect to the vehicle with PTT.
4. Start the engine.
5. Rerun the Diagnostic Monitor.

Cause
Fault Code P1031 - Particulate Matter (PM) Sensor Clogged Tip may occur in GHG17
vehicles that are equipped with a vertical SCR catalyst. P1031 may be accompanied by
P24DA - PM Sensor Exhaust Sample Error. When the Confirmed DTC status is
checked in Detailed Fault Information from the Diagnose screen in Premium Tech Tool
(PTT), status will show True.
Solution
DO NOT Replace the PM sensor for P1031 and/or P24DA on vehicles
configured as described above prior to performing the steps below.
Verify the chassis emissions level
- Details can be found in the Product Details box on the Product tab in PTT as seen
below:
Review the Detailed Status Information for the relevant code on the DTC
Readout.
Once the chassis is confirmed to be US17+OBD16 or US17+OBD18:
Software improvements have been made that address this DTC. There are two
documents that should be reviewed:
1. Product Improvement PI0883 Engine Control Module (ECM) and
Aftertreatment Control Module (ACM), Software Updates was released July
2018. This product improvement should appear under the Campaigns section
of the Product screen of Premium Tech Tool (PTT) when first connecting to the
vehicle. Applicability to this campaign should be checked first.
- The Service Program document can be found on the dealer Mack Trucks
eMedia.
• Note: There will be a prompt to sign in to the Trucks Dealer Portal site
if necessary.
• Searching for PI0883 will return a link to the bulletin.
- If the PI applies to the product it is not necessary to proceed to the
Field Service Bulletin below.
2. Field Service Bulletin FSB 284-067 Engine Control Module (ECM) and
Aftertreatment Control Module (ACM), Reprogramming has been released and
should be reviewed if the Product Improvement does not apply to the vehicle.
- The FSB document can be found on Mack Trucks eMedia or under the
Service tab in Impact.
• Searching for 284-067 will return a link to the document in either
application.
3. If either of the above documents applied and there are no other issues present,
the vehicle should be released when software updates have been completed.
If software is current according to the bulletin, refer to CBR Solution K59554
255 for more information.
If other symptoms or related codes are present, normal diagnostics will need
to be performed to determine the cause.

• The bulletin can be found under the Service tab in Impact by searching for either the
FSB number, or by reviewing the articles under Function Group 284.
• If the article does not appear when searched with either VIN or Chassis information
entered, search by model:
1. Clear any chassis information from the Search box.
2. Select or enter VN as the model.
3. Make sure Title is selected in the Search By field. Enter "FSB 284-067" in the
text entry field.
4. Press the Search button. The operation will appear in the results window.
5. Mutiple article choices will appear. Find the Operation for the correct Chassis.
Note: It is possible that more than one choice will have the same title (as
shown below). Despite having the same title, the Operations are different
and should be reviewed to locate the correct procedure.
6. Following software updates, perform Operation 2589-08-03-17 After-treatment
Particulate Sensor, Diagnostic Monitor found under the Test tab in Premium Tech
Tool (PTT) to verify that there are no further issues.
If software is current according to the bulletin, refer to CBR Solution K47547856 for
