2017~2025 Mazda orange engine warning light

[NikkoFrench]

Hello, I own a 2019 Mazda CX-5 2.2 184 ADW automatic. My engine warning light has unfortunately come on.

There's no loss of power.

My battery is slightly low (that might be related).

I have a friend with a diagnostic tool.

The error code displayed is "P2426 Particulate Matter Sensor Circuit."

I'm looking for any clues, or if anyone has had this problem and if so, how did they resolve it?


Thank you in advance for your help.

P.S.: I'm French.

Start with the battery. Many issues are caused by a low, dead or dying battery. The code refers to a low voltage signal, but that could be because of the battery. So get that sorted out first, reset the code and see what happens.

The error code is P24C6, sorry..
Okay, I'll start with that, hoping the warning light goes away with it.
Merci !

From Google ...

The Mazda P24C6 code signifies a fault in the Particulate Matter (PM) Sensor Temperature Circuit, often due to water condensation or a failing sensor, common in diesel models like the CX-5 2.2L SKYACTIV-D, triggering the check engine light and sometimes an "Engine Oil Level High" message. Diagnosis involves checking sensor wiring, but usually requires replacing the PM sensor and potentially reprogramming the control unit, as per Mazda service bulletins.

--------------

The PM temperature sensor gets moisture on it and sends an out of range error sometimes on startup. The 2nd time in a row will trip the CEL.

Choices are either replace the sensor ($1500ish) or get FORscan to reset the code periodically as needed.
