Truck is throwing this code P2452 😑
Hopped in the rig went into the store to buy some came out and this code was thrown anybody experienced this is it something minor like a faulty sensor for perhaps I hope I'm still under warranty

Diesel Particulate Filter Pressure Offset Test
The DPFP Sensor is checked during after-run conditions (period where the key is turned off, however the ECU is still powered), to verify that the sensor has not drifted from the ambient with no exhaust flow. This test is performed by comparing the sensed pressure to a threshold (due the gauge sensor, this value should be 0)
Diesel Particulate Filter Pressure Sensor Offset Check
DTCs P2452 – DPFP Sensor Circuit "A"
Monitor Execution Afterrun
Monitor Sequence None.
Sensors OK DPFP Sensor
Typical Monitoring Duration 1 second.
