Does anyone know where to locate the exhaust particulate sensor .? Sob dealership wants 800$ for a part that costs 150$ . Thanks in advance

What code do you have? I don't think there is an actual sensor that measures particulate matter. It's basically an algorithm made up of fuel burned, dpf delta pressure, and other factors. What is the dealer trying to sell you?

Perhaps it's actually the differential pressure sensor they are replacing.


Beginning with 2017 Silverado and Sierra models, the DPF Soot Accumulation is measured in percent instead of grams in GDS 2. The ECM will not try to perform a regeneration until the DPF Soot Accumulation increases to approximately 100%. If the DPF Soot Accumulation increases to 115% and the system has not been able to regenerate, the “Continue Driving” message will display on the Driver Information Center (DIC). If the DPF Soot Accumulation increases to 140%, DTC P2463 (DPF Soot Accumulation) will set and a service regeneration will be required to clean the DPF.

There are two soot level readings in GDS2. One uses the differential pressure sensor to calculate the soot in the DPF and the other uses other engine data. If either of these reaches the threshold, a regeneration will be performed.

Differential pressure sensor is $16. Could be claiming egr dpfe pressure sensor which is $174.
