P24B3: The Low Pressure Fuel System Sensor Circuit – Explained
The P24B3 fault code is related to the Particulate Matter (PM) sensor in diesel engines.
The PM sensor monitors the amount of soot in the exhaust gas. The sensor has a ceramic element with comb-shaped Interdigital Electrodes (IDE), a heater, and a positive temperature coefficient resistor for temperature measurement. The sensor performs a regeneration to clean off soot before the measurement phase begins.
The P24B3 code is set when the sensor control unit detects an internal fault of the sensor, fault of the sensor circuitry, or low voltage on the sensor supply circuit.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the P24B3 fault code. This code is usually caused by a faulty exhaust particulate matter sensor, an open or shorted sensor harness, or a poor electrical connection in the sensor circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
If you’re experiencing the P24B3 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may have a faulty Exhaust Particulate Matter Sensor, an open or shorted harness, or a poor electrical connection. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify any issues and determine the best course of action to resolve the problem.
Ignoring the P24B3 fault code, caused by a faulty exhaust particulate matter sensor, can lead to serious consequences.
