P1478: Understanding The Causes And Solutions For This Fault Code
The P1478 fault code refers to a problem with the Particulate Matter (PM) sensor in the diesel exhaust system. This sensor monitors the amount of soot in the exhaust gas.
The PM sensor has a ceramic element with comb-shaped electrodes and a Sensor Control Unit (SCU). It works by measuring the electrical conductivity of the diesel particulate.
Soot is absorbed between the electrodes, creating a conductive path that generates a current. To ensure accurate readings, the sensor performs a regeneration process to clean off the soot before measurement. The number of regenerations is based on the vehicle’s strategy.
Once the preset number is reached, the cumulative current readings determine the soot concentration in the exhaust gas and the efficiency of the Diesel Particulate Filter (DPF). The P1478 fault code is triggered when the PM sensor control unit detects a fault in the sensor circuitry, specifically a high voltage in the temperature circuit. This indicates a problem with the sensor’s ability to accurately measure the soot concentration.
