What does code P245E mean?

Q: What does code P245E mean?

Particulate Filter Pressure Sensor B Circuit. P245E indicates that the powertrain control module has detected an electrical fault in the circuit for particulate filter pressure sensor B, which is the downstream or outlet pressure sensor on a diesel particulate filter. The computer monitors the sensor signal voltage and compares it to expected values; when the voltage stays out of range or the circuit resistance is abnormal, it stores this code and illuminates the check engine light.
