12667010 Exhaust Particulate Sensor For 2016 Chevy Express 2500 GMC Sierra 3500

Exhaust Particulate Sensor for Chevrolet Express 2500 & GMC Sierra 3500

This exhaust particulate sensor replaces OE part 12667010 and monitors soot levels in the diesel exhaust stream to help the engine control module manage regeneration cycles on 2016 Chevrolet Express 2500 and GMC Sierra 3500 trucks.

Overview

The exhaust particulate sensor for Chevrolet Express 2500 and GMC Sierra 3500 reads particulate matter concentration downstream of the diesel particulate filter. It provides real-time feedback to the ECM for efficient DPF regeneration, helping maintain emission system performance on 2016 light- and medium-duty diesel platforms. Fleet operators and repair shops rely on this sensor to diagnose soot loading issues and restore proper exhaust aftertreatment function.

Built For Performance

• Direct-fit connector matches factory harness for plug-and-play installation
• Accurate soot measurement aids precise DPF regeneration timing
• Rugged sensor housing resists exhaust heat and road debris
• OEM-spec response curve keeps ECM data within expected range
• Corrosion-resistant pins and sealed body prevent moisture intrusion
• Pre-calibrated element eliminates need for manual setup after replacement

Fits These Machines

• for 2016 Chevrolet Express 2500
• for 2016 GMC Sierra 3500

On-The-Job Use

• Replacing a contaminated or failed particulate sensor that triggers DTC P24A0 or similar codes
• Routine DPF system service and regeneration troubleshooting
• Fleet maintenance of delivery vans and utility trucks
• Restoring correct back-pressure and soot calculation after sensor drift

Specs At A Glance

Good To Know

Q: Will I need to reset the DPF learned values after installing this sensor? A: Most scanners require a DPF regeneration reset and a learned value clear; performing the reset ensures the ECM uses the fresh signal from the new exhaust particulate sensor for accurate soot calculation.

Q: Can a faulty sensor cause the truck to enter reduced power mode? A: Yes, when the ECM receives implausible particulate readings it often triggers a derate or limp mode to protect the aftertreatment system, so replacing a failing sensor quickly restores normal power.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
