What does code P24C8 mean?

Q: What does code P24C8 mean?

Particulate Matter Sensor Temperature Circuit Low. P24C8 indicates that the powertrain control module has detected a low voltage condition on the particulate matter sensor temperature circuit, which is used to monitor the sensor's internal heater temperature. The circuit is expected to show a voltage within a calibrated range, and a value below the threshold for a set time triggers this code.
