Basic DTC analysis according to OBD2 protocol standard.

OBD2 or On-Board Diagnostics displays messages for basic group styles. More comprehensible code composition has been standard since 2000. The DTC code consists of five characters and its composition will be shown in this video

Insight into programming

The basic unit for the operation of any computer is the bit. Logic 0 and 1 are expressed by a single bit. Diagnostics The error code is composed of 16 bits. The first two bits define one of the four basic circuits. The video will show you a comprehensive overview of the composition of the error report

Particulate Matter Sensor Processor Performance

Cause of DTC

The Particulate Matter (PM) Sensor is used to determine the efficiency of the Diesel Particulate Filter (DPF) by measuring the amount of particulate matter (soot) remaining in the exhaust gas after the DPF. The PM Sensor is located at the outlet of the Selective Catalytic Reduction (SCR) Catalyst, and consists of a probe and module which cannot be replaced separately of each other and must be replaced as a unit. The module communicates and shares information with the Powertrain Control Module (PCM) over the J1939 Data Link. The probe contains three internal parts: a heater, a temperature sensor, and a set of particulate measuring electrodes with a high electrical resistance. During normal operation, the module will activate the heater and perform a regeneration of the electrodes to burn off any deposited soot before taking a measurement. After sensor regeneration is complete, soot particles from the exhaust gas are then collected onto the electrodes and form conductive paths between the electrodes leading to a drop of the electrical resistance. The decreased resistance results in an increased current across the electrodes, which is compared against calibrated thresholds to determine sensor functionality and DPF efficiency.
