What does code P24B0 mean?

Q: What does code P24B0 mean?

Particulate Matter Sensor Circuit Low. P24B0 indicates that the powertrain control module has detected a low voltage condition on the particulate matter sensor circuit, which is used on diesel vehicles to monitor soot levels in the exhaust. The computer expects a signal within a specific voltage range, and a reading below that threshold triggers this code.
