Genuine: Original manufacturer part. This product is the original part designed and produced by the vehicle manufacturer.
Particulate Matter Sensor - the soot-measuring sensor in the exhaust aftertreatment circuit of the 2.0L AJ20D4 diesel engine.

The sensor is fitted in the exhaust downstream of the diesel particulate filter. Its heated sensing element collects soot from the passing gas flow, and the resulting change in electrical resistance across the element is reported to the engine control module. From that signal the control module assesses how effectively the particulate filter is trapping soot and raises a fault when filtering efficiency falls below the on-board diagnostic threshold, which is why the sensor is fitted only to emissions specifications that require diagnostic monitoring of the DPF.

The sensing element cannot be cleaned, recalibrated or serviced separately, and it operates in a high-temperature position - a sensor reporting out of range or with a damaged lead is replaced as a unit.

Frequently asked questions

What does the particulate matter sensor do?
This particulate matter sensor measures soot in the exhaust downstream of the diesel particulate filter on the 2.0L AJ20D4 diesel. Its heated element collects soot and the change in resistance is reported to the engine control module, which assesses how well the DPF is trapping soot.
Can this PM sensor be cleaned or repaired?
No. The sensing element can't be cleaned, recalibrated or serviced separately and works in a high-temperature position. A sensor reading out of range or with a damaged lead is replaced as a complete unit on the 2.0L diesel.
Which vehicles does this particulate matter sensor fit?
Fits the Discovery Sport (2015+) and Range Rover Evoque L551 (2019+) with the 2.0L AJ20D4 diesel, on EU6D, Bharat VI and Japanese emissions specifications. Confirm your emissions spec, since it's only fitted where DPF monitoring is required.
