The WJIECO 68250216AA PM sensor is the original-design diesel particulate matter (PM) sensor used on 2014-2018 Ram 1500 and 2019 Ram 1500 Classic pickups with the 3.0L V6 EcoDiesel engine. Mounted in the exhaust stream, it measures soot concentration downstream of the diesel particulate filter and feeds that data to the engine control module, which uses it to schedule DPF regeneration. This early part number was later updated by Mopar, and ordering the superseding revision is a smart upgrade for anyone whose truck still carries the original unit.

## Fitment and Compatibility

### Compatible Vehicles

– 2014-2018 Ram 1500 – 3.0L V6 EcoDiesel (GEN 2)
– 2019 Ram 1500 Classic – 3.0L V6 EcoDiesel (GEN 2)

This 68250216AA PM sensor installs in the factory port and works with the stock connector, so the replacement stays a plug-and-play swap. It is built only for the 3.0L V6 EcoDiesel; gas and HEMI trucks do not use this sensor at all.

### Interchangeable Part Numbers

The WJIECO 68250216AA PM sensor cross-references these numbers:

– Mopar: 68171189AA
– Bosch: 0281007482, 0281007480

Mopar later superseded this design with 68250216AB, 68250216AC, and 68250216AD. If your truck came from the factory with 68250216AA, any of these revised numbers fits the same port and connector. Always confirm the OE number stamped on your original sensor before you order.

## How the Diesel PM Sensor Works

### What It Measures

A heated element inside the sensor estimates the soot mass trapped in the DPF. The signal climbs as the filter loads; once it crosses the engine control module’s threshold, the module starts a high-temperature regeneration cycle that burns the soot off and restores filter capacity. The reading is relayed over the truck’s data bus, which is why a drifted sensor also skews the soot-load percentage some owners watch on the dash.

### Why Accurate Readings Matter

When a 68250216AA PM sensor drifts or fails, the ECM makes regen decisions from bad data. The truck may regenerate too often and waste fuel, or wait too long until the filter clogs and power drops into limp mode. Swapping in a fresh sensor restores the soot readings that keep regeneration timing, fuel economy, and driveability on track on the 3.0L EcoDiesel, and it protects the DPF from an expensive early replacement.

## Signs Your PM Sensor Needs Replacement

Watch for these symptoms on a 2014-2018 Ram 1500 3.0L EcoDiesel:

– DPF or exhaust filter warning messages and reduced power
– Check engine light with soot or DPF efficiency codes (for example P2453, P2454)
– Back-to-back regen cycles or cycles that never complete
– Noticeably worse fuel economy on long highway trips

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

## Installation Overview

1. Park on level ground, let the exhaust cool completely, and locate the sensor on the DPF assembly.
2. Disconnect the electrical connector and remove the old sensor with the correct socket.
3. Install the new WJIECO 68250216AA PM sensor into the same port.
4. Reconnect the connector, start the engine, and clear stored codes with a scan tool.

Most owners finish in 20-30 minutes with basic hand tools, and no programming is needed after the installation.

## Why Choose WJIECO

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

For the early EcoDiesel 1500 owner, the WJIECO 68250216AA PM sensor is the cost-effective upgrade path that restores normal regen behavior and keeps the Ram 1500 out of the service bay.
