RA0111531228 | Genuine Detroit Diesel® Exchange Soot Particulate Sensor

1. Restore Emissions System Function

The soot particulate sensor:

• Monitors soot levels in the exhaust

• Communicates with the engine control module

• Helps control Diesel Particulate Filter (DPF) regeneration

Ordering it replaces a failed sensor so the vehicle can:

• Clear fault codes

• Prevent engine derate

• Pass emissions requirements

• Operate normally

2. Reduce Cost in the Purchase Order

When listed as “Exchange” on an order, it means:

• You are buying a remanufactured unit

• A core charge may be included

• You must return the old sensor

• You receive core credit after return

This lowers the total repair cost compared to a brand-new part.

3. Minimize Downtime

Exchange parts are often:

• In stock

• Ready to ship immediately

• Faster than waiting for new OEM production

This is especially important for fleet trucks where downtime costs money.

1. Check Engine Light (MIL)

• Active fault codes related to particulate matter/soot sensor

• Common DTCs: PM sensor circuit fault, signal implausible, short to ground/power

2. Frequent or Failed DPF Regeneration

• Truck keeps trying to regen too often

• Regeneration fails to complete

• DPF soot level readings don’t match actual condition

3. Engine Derate (Reduced Power)

• Vehicle goes into limp mode

• Speed or RPM limited

• Warning messages about emissions system

4. Poor Fuel Economy

• Excessive regens increase fuel use

• Engine runs inefficiently due to incorrect soot readings

5. Inconsistent Sensor Readings (Scan Tool)

With a diagnostic tool, you might see:

• Soot levels stuck at 0% or 100%

• Values not changing during operation

• No communication with the sensor

6. Failed Emissions Test

• High particulate readings

• Inspection failure due to emissions codes
