2015 Ram 1500 EcoDiesel Particulate Matter Sensor Location

The particulate matter (PM) sensor on a 2015 Ram 1500 EcoDiesel is located downstream of the diesel particulate filter (DPF).

The PM sensor measures the amount of particulate matter in the exhaust gas and sends this information to the engine control module (ECM). The ECM uses this information to control the regeneration of the DPF.

If the PM sensor fails, the ECM will not be able to accurately measure the amount of particulate matter in the exhaust gas. This can cause the DPF to not regenerate properly, which can lead to the DPF becoming clogged and the engine to malfunction.

To replace the PM sensor on a 2015 Ram 1500 EcoDiesel, you will need to remove the DPF. This is a relatively complex procedure and should only be performed by a qualified mechanic.

Here are some of the signs that your PM sensor may be failing:

  • Check engine light
  • Engine hesitation
  • Loss of power
  • Black smoke from the exhaust

If you are experiencing any of these problems, it is important to have your PM sensor checked by a qualified mechanic.

Here are some tips to prevent your PM sensor from failing:

  • Keep your diesel fuel clean and free of contaminants.
  • Operate your vehicle within the recommended speed and RPM range.
  • Avoid idling your vehicle for extended periods of time.

If you follow these tips, you can help to extend the life of your PM sensor and prevent it from failing.
