The WJIECO 68299062AA PM sensor is a direct-fit diesel particulate matter (PM) sensor for 2016-2017 Ram 2500, 3500, 4500, and 5500 trucks with the 6.7L inline-six Cummins turbo diesel. Mounted in the exhaust system, this sensor continuously measures soot loading inside the diesel particulate filter (DPF). It feeds that data to the ECM so a regeneration cycle starts at the right moment, keeping the filter clear and the truck out of limp mode. When this sensor starts sending bad readings, the Cummins loses its regeneration strategy, and a clogged DPF is a much bigger bill than a sensor swap.

## Fitment and Compatibility

### Compatible Vehicles

– 2016-2017 Ram 2500 – 6.7L i6 Cummins turbo diesel
– 2016-2017 Ram 3500 – 6.7L i6 Cummins turbo diesel
– 2016-2017 Ram 4500 / 5500 (chassis cab) – 6.7L i6 Cummins turbo diesel

This 68299062AA PM sensor is a direct replacement for the factory unit. It mounts into the original sensor port and uses the factory electrical connector, so no wiring work or programming is required. If your truck runs the 6.4L gas engine or an older 5.9L Cummins, this sensor does not apply.

### Interchangeable Part Numbers

The WJIECO 68299062AA PM sensor is part of the Mopar heavy-duty PM sensor family and cross-references:

– Mopar: 68352149AA, 68404997AA (successor revisions)

These numbers identify the same DPF soot sensor application across production runs. Confirm the OE number on your original sensor before ordering, because Ram used several revisions across model years.

## How the Diesel PM Sensor Works

### What It Measures

The PM sensor estimates the mass of soot trapped in the DPF. A heated sensing element reads the soot concentration in the exhaust flow, and the signal climbs as the filter loads up. When the soot threshold is crossed, the ECM commands a high-temperature regeneration that burns the accumulated soot off and returns the filter to a clean state.

### Why Accurate Readings Matter

A failing 68299062AA PM sensor sends incorrect soot data to the ECM. The truck may regenerate too often, wasting fuel and putting heat stress on the DPF, or it may skip regeneration until the filter plugs and triggers limp mode. Replacing the sensor restores proper regeneration timing, fuel economy, and full pulling power on the 6.7L Cummins. Catching the problem early with a fresh sensor protects the filter and avoids a forced regen or a tow to the shop.

## Signs Your PM Sensor Needs Replacement

Watch for these symptoms on a 2016-2017 Ram HD with the 6.7L Cummins:

– DPF warning messages, reduced power, or limp mode under load
– Check engine light with soot or DPF efficiency codes (for example P2453, P2454)
– Regeneration cycles that run more often than usual or never complete
– Higher fuel consumption and frequent exhaust filter cleaning messages

If your truck is storing a diagnostic trouble code, look up the exact definition and the likely causes on the free code library at [OBD-Codes.com](https://www.obd-codes.com) before replacing parts.

## Installation Overview

1. Park on level ground, let the exhaust cool down, and locate the PM sensor on the DPF assembly.
2. Disconnect the electrical connector and remove the old sensor with the correct socket.
3. Fit the new WJIECO 68299062AA PM sensor into the same port and tighten to the original position.
4. Reconnect the connector, start the engine, and clear any stored codes with a scan tool.

The job usually takes about 20-30 minutes with basic hand tools, and no sensor programming is required after install.

## Why Choose WJIECO

– Direct-fit replacement built to OEM specifications
– Sealed, heat-resistant housing built for high exhaust temperatures
– Factory-matched connector and thread for a clean bolt-in install
– Each unit is inspected before packing to reduce defect returns
– 12-month warranty and responsive after-sales support

For the 6.7L Cummins owner, the WJIECO 68299062AA PM sensor is the dependable, budget-friendly replacement that keeps the DPF system regenerating on schedule and keeps the Ram HD hauling without downtime.
