What does code P24AE mean?

Q: What does code P24AE mean?

Particulate Matter Sensor Circuit. P24AE is a generic OBD-II code that indicates the powertrain control module (PCM) has detected a fault in the particulate matter (PM) sensor circuit. The PM sensor measures soot levels in the exhaust stream, primarily on diesel vehicles equipped with a diesel particulate filter (DPF), and the PCM sets this code when the sensor's electrical signal is out of range or inconsistent with expected values.
