** 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.
As of 10 April 2018, the Tech Tip below is still current
information. If diagnostics indicate that sensor replacement is
required, instructions should be followed.
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.
• If the Diagnostic Monitor fails after any of the operations below, 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.
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. Repair can be verified with just KEY ON as
diagnostics run immediately.
- If wiring harness and connections check isolates the problem to the sensor:
Following replacement, run 2589-08-03-17 After-treatment Particulate Sensor,
Diagnostic Monitor and confirm no faults return before releasing the vehicle.
• 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.
2. Update the Engine Control Module (EMS) software and clear all codes.
3. Run 2589-08-03-17 After-treatment Particulate Sensor, Diagnostic Monitor a
nd confirm no faults return before releasing the vehicle.
- If the PM sensor is the current part number:
1. Verify that the EMS software is current.
2. Run 2589-08-03-17 After-treatment Particulate Sensor, Diagnostic Monitor a
nd confirm proper function.
NOTE: It may be necessary to follow the steps in the IMPORTANT
notes above to verify correct operation
3. If the sensor is verified to be malfunctioning, replace it and retest.
• 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. Update the Engine Control Module (EMS) software.
2. Clear codes.
3. Update the PM sensor to the current part number.
4. Run 2589-08-03-17 After-treatment Particulate Sensor, Diagnostic Monitor and
confirm no faults return before releasing the vehicle.
