P118B Fault Code: Understanding The Description And Troubleshooting Tips
The P118B fault code indicates that the temperature of the particulate matter sensor is not plausible. This sensor is responsible for monitoring the amount of soot in the diesel exhaust gas. It works by measuring the electrical conductivity of the particulates in the exhaust gas. The sensor has a ceramic element with comb-shaped interdigital electrodes, a heater, and a temperature measurement resistor.
As the exhaust gas flows over the sensor, soot is absorbed between the electrodes, creating a conductive path. This path generates a current based on the applied voltage. To ensure accurate readings, the sensor undergoes a regeneration process where the soot is cleaned off by heating the element.
Once a preset current value is reached, the measurement phase begins. The number of regenerations is determined by the vehicle’s strategy. When the calibrated number of regenerations is reached, the cumulative current readings are used to determine the concentration of soot in the exhaust gas.
This information is crucial in determining the efficiency of the diesel particulate filter. If the P118B fault code appears, it means that the temperature reading from the particulate matter sensor is not plausible.
This could be due to a faulty sensor, wiring issues, or a problem with the sensor control unit.
It is important to address this issue promptly to ensure accurate monitoring of the soot levels in the exhaust gas.
