This code indicates the engine control module cannot establish data communication with the particulate filter pressure sensor. It suggests a breakdown in the network link rather than a simple signal voltage discrepancy. Without this data, the vehicle cannot accurately monitor soot accumulation in the filter.
Heat and vibration near the exhaust often crack insulation or loosen terminals at the sensor.
The sensor itself may have an internal failure preventing it from broadcasting data on the network.
Moisture entering the electrical connection can interrupt high-speed data signals.
A protective fuse for the sensor network power may have opened due to a short.
Physical damage to the CAN or LIN bus wires prevents data transmission between components.
Internal failure within the control module is possible but statistically rare compared to wiring or sensor faults.
No, communication codes are rarely caused by the PCM itself; wiring or the sensor is the usual culprit.
Short distances are possible, but prolonged driving may cause DPF clogging or reduced power modes.
Only if the issue was a temporary glitch; physical wiring or component faults will cause the code to return.
No, this indicates no data is being received, whereas range codes indicate data is present but illogical.
