P2460 OBD Error Code: Problem & Solutions

<<See All OBD Codes    

The trouble code P2460 can be elucidated as Diesel Particulate Filter Pressure Sensor B Circuit Low Issue. It is a generic diagnostic trouble code which would indicate there is some fault in the diesel particulate filter. It would mean that the diesel particulate filter efficiency has dropped below the given threshold for sensor B.

This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another. The diesel particulate filter is being monitored by the engine control module. This trouble code would be set by the ECM when the diesel particulate filter would not be as per the specifications set by the manufacturer.

What causes this problem with the Diesel Particulate Filter Pressure Sensor 'B' Circuit Low?

• There can be distorted DPF filter
• Imperfect exhaust pressure sensor
• Poor connection to the DPF and the pressure sensor
• Driving at less speed for a very long period of time
• Ash accumulation inside the filter
• Unnecessarily high sulphur content in the fuel

1. Engine Control Module - It is not always the components, but the ECM that can also be faulty. It can cause misinterpretation of correct data thus leading to wrong operational decisions which will affect the transmission and overall engine performance. Thus, replace faulty module and reprogram it now!
2. Powertrain Control Module - Powertrain Control Module can also be faulty in rare cases and thus needs through checks for system and software errors. Thus check and replace it, if required.
3. Diagnostic Tool - It is always advisable to use correct tools and equipment while resolving any OBD code issue as even small mistakes can lead to wrong diagnosis. Thus, always take help from a professional who has the knowledge and experience to such tools in efficient manner. Buy new quality diagnostic tools from us today!
4. Electronic Control Unit – ECU monitors the temperature differences in the boost converter with the help of the temperature sensors to prevent the converter from overheating and malfunctioning. Thus, replace faulty ECU immediately.
5. Exhaust Gas Recirculation Valve - Did you just see check engine light flashing on your dashboard? If the computer would detect some fault with the automobile’s EGR valve circuit, then it would set up the check engine light so that the driver is notified about the fault. Don’t waste time and get them replaced or else this fault code can turn up.
6. Diesel Exhaust Fluid Pump - The diesel exhaust fluid pump needs to work properly if the transmission system has to perform. If it is not functioning, the transmission may slip and cause harsh shifts too. Thus replace faulty pump now and buy a new one from us!
7. Diesel Particulate Filter - Diesel particulate filters are designed to trap particles of soot in the flow of exhaust gases from diesel vehicles and convert them into CO2 during the regeneration phase. This helps to keep the air clean.

Willing to know some common symptoms of OBD Code P2460? Your wish is our demand. Have a look at them below:

Common Symptoms

• Check engine light can start flashing up
• Affected fuel economy
• Reduced Engine performance
• Sometimes there might be no visible symptoms present
• Black smoke might start emitting from the tailpipe during acceleration

We have listed out so ways which would help you to correct the occurrence of OBD Code P2460. They are mentioned here as follows:

• Repair or replace the loose, broken or corroded wiring
• Rehabilitate the defaults in the reduction pump circuit
• You must fix the defective or corroded connectors
• Make sure to mend the faulty exhaust system parts
• Carefully adjust the faults in the exhaust gas temperature sensor (EGTS)
• Recondition the non-functioning terminals
• Diesel Particulate Filter replacement
• Exhaust Gas Temperature Sensor replacement

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of PCM, Diesel Particulate Filter, ECM, Exhaust Pressure Sensor, Diesel Exhaust Fluid, Hydraulic Pressure, Exhaust Gas Temperature and many more. Now all your problems would vanish within no time.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• Initial step is to visually examine the wiring for faults, frays, or wires that have melted.
• Visually inspect the connector for damage, frays, or corrosion. Make sure to mend the defective wiring or connectors as per the requirement.
• The mechanic should retest the system to make sure that the wiring and connectors are in good working condition.
• The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
• After performing a careful inspection, every of the stored codes and freeze frame data are retrieved as it can help down the way for further diagnosis process.
• He will know that an intermittent condition persist, if the code does not return instantly.
• Intermittent conditions are very tough to diagnose, and they need time to get worse before they can be diagnosed correctly.
• Check the circuitry of the exhaust gas temperature sensor EGTS)/exhaust gas pressure sensor (EGPS) near where the hot exhaust constituents are close to wiring and connectors.
• Rehabilitate the defaults in the circuitry. The entire system should be retested to make sure that the circuitry of the exhaust gas temperature sensor and pressure sensor are in good working condition.
• After that it is essential to examine the resistance of the EGTS/EGPS. The specifications of the resistance are decided by the manufacturer, but are typically 150 ohms. A resistance reading of below 50 ohms would indicate that there is need to replace the defective sensor.
• A heating component should be used to examine the resistance with the volt/ohmmeter. The level of the resistance would decline when the heating component is added and would rise when the sensor would cool.
• If this would not happen, then it would indicate that there is a need to restore the faulty EGTS/ EGPS.
• The voltage of the EGTS /EGPS, at the electrical connector should be checked properly. Keep in mind that the reading of the voltage should be at 5-volts.
• Now if the voltage reading of the EGTS/EGPS would not be at 5-volts, then you should inspect the continuity between the PCM and the signal wire.
• There would be a need to replace or reprogram the PCM if there is continuity.
• There might be some flaws in the reductant injection air controller if no voltage is present on the sensor connector.
• If the mechanic finds out that there is no voltage present in the sensor connector, then it would that there are some quirks in it. Reprogram the defective reductant injection air controller.
• Now if you find out that the code is reappearing, then the next step would be to visually inspect the DPF or wiring for faults. After that the live engine data should be observed while the engine is operating and the throttle will be depressed looking for a change in the readings of the exhaust pressure sensor.

Common Mistakes When Diagnosing the P2460 Code

• A lot of mistakes are made if the diagnostic steps are not followed in the exact order.
• A most common mistake is to restore the DPF when it just needed to be driven at freeway speeds to clear the filter out.
