The WJIECO 68323482AA PM sensor is a diesel particulate matter (PM) sensor listed for Ram pickup diesel applications, with aftermarket listings also pairing it to the 2017-2020 Jeep Wrangler 2.2L diesel (EU spec) and the 2020 Wrangler diesel. Mounted in the exhaust stream, it reports soot loading to the ECM so a DPF regeneration cycle starts at the right moment. Because fitment across Ram and Wrangler diesel variants varies by market and model year, always verify the OE number stamped on your original sensor before you

Fitment and Compatibility

### Compatible Vehicles

– Ram pickup diesel vehicles (per the WJIECO compatibility list)
– Aftermarket listings also show: 2017-2020 Jeep Wrangler 2.2L diesel (EU spec); 2020 Jeep Wrangler diesel

This 68323482AA PM sensor is a direct bolt-in replacement for the factory unit wherever the original OE number matches. It uses the original mounting port and the factory electrical connector, so no cutting, splicing, or programming is involved. If your Ram is a gasoline model or your Wrangler is a gasoline variant, this sensor does not apply to your vehicle.

### Interchangeable Part Numbers

The WJIECO 68323482AA PM sensor cross-references Bosch 0281007212 and 0281007260. If the part on your truck carries either Bosch number, this replacement should fit. When in doubt, send us a photo of your original sensor label before ordering – confirming the OE number is the single best way to avoid a wrong-fit return.

## How the Diesel PM Sensor Works

### What It Measures

The PM sensor uses a heated sensing element exposed to exhaust flow to estimate how much soot has accumulated in the DPF. As the filter loads up, the sensor signal climbs steadily. When the soot level crosses the ECM threshold, the controller commands a high-temperature regeneration that oxidizes the trapped soot and returns the filter to a clean state.

### Why Accurate Readings Matter

A failing 68323482AA PM sensor sends the ECM bad soot data. The vehicle may regenerate too often, wasting fuel and adding heat cycles to the DPF, or it may delay regeneration until the filter plugs and power drops away. Replacing the sensor restores normal regen timing, fuel economy, and driveability. Catching the problem early also protects the DPF, which is a much bigger ticket item than the sensor itself.

## Signs Your PM Sensor Needs Replacement

Watch for these symptoms on a Ram pickup diesel or a diesel Wrangler:

– DPF or exhaust filter warning messages, reduced power, or limp mode
– Check engine light with soot or DPF efficiency codes (for example P2453, P2454)
– Regen cycles that run back to back or never seem to complete
– Noticeably worse fuel economy on highway driving

## Installation Overview

1. Park on level ground, let the exhaust cool fully, and locate the PM sensor on the DPF assembly.
2. Disconnect the electrical connector and remove the old sensor with the correct socket.
3. Install the new WJIECO 68323482AA PM sensor into the same port and seat it back to the original position.
4. Reconnect the connector, start the engine, and clear stored codes with a scan tool.

Most owners finish the swap in 20-30 minutes with basic hand tools, and no sensor calibration is required after the install.

## Why Choose WJIECO

– Direct-fit replacement built to OEM specifications
– Sealed, heat-resistant housing tested 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 with responsive after-sales support

For the Ram pickup diesel or diesel Wrangler owner who has confirmed the OE number, the WJIECO 68323482AA PM sensor is the dependable, budget-friendly replacement that keeps the DPF regenerating on schedule and keeps the vehicle out of the shop.
