What is the P2002 Fault Code and how does it work?
The fault code “P2002 Diesel particulate filter efficiency lower than threshold” This is due to the emissions system. For diesel vehicles produced in 2007 and later, a new exhaust system has been installed with a diesel particle filter (DPF). This filters out soot from exhaust. This fault code can be activated on cars and trucks of the following brands: Volkswagen, Audi, Ford and Citroen; Dodge, Lexus, Lexus, Lexus, Lexus, Ford and Citroen; and even construction machinery.
While operating, the DPF creates slight pressure. Thanks to the pressure feedback sensors on the DPF, the ECU monitors the DPF. It will generate the fault code P2002 to alert the driver if it detects any inconsistency between the pressure limits during two rides.
DPF can burn soot and remove it. DPF is the final line of defense against emissions. Because it is capable of working in extreme conditions, DPF is built to last. The code will automatically clear when the regeneration process is completed. P2002 is a warning sign for a fault that has been detected and will be cleared when it is fixed. The code will remain fixed until it is repaired and can be deleted manually using the OBD scanner.
What are the Signs and Symptoms of P2002 Misfunctions?
- – To burn the DPF, the engine management system raises exhaust temperature. This can lead to an increase in fuel consumption.
- The code P2002 will bring on the “Check Engine Light”. While the DPF regenerates, the light might stay on continuously or intermittently. The acceleration of your vehicle will decrease when you push the gas pedal.
- DPF renewal can increase engine temperature, which can cause oil properties to deteriorate and oil life to be reduced.
- – The vehicle will go into Limp Mode if the DPF isn’t cleared.
What is the P2002 Fault Code?
- This code is caused by the slowness and time taken to complete the process. To melt the soot, DPF requires heat of between 500c and 600c. Despite all its efforts, the ECU can’t generate enough heat at low revs to clear the DPF.
- Air leaks caused by DPF can alter sensor values and create a fault code.
- ECU is not working
- – High sulfur fuels can cause the DPF to clog rapidly
- – Modifications to the vehicle and accessories
- – Defective DPF
Diagnostics and Repair Methods for P2002
DPF-related problems can be solved only in a limited way. The DPF can become temporarily clogged with soot particles. The DPF must be visually checked if the malfunction lamp is lit and code P2002 has been entered.
Make sure to check for loose connections between the engine and 1st row exhaust.
You should inspect the sensors located between and in front or behind the DPF. You must inspect the connectors and cables. The DPF must not be exceeded by the sensor wires. You should also inspect the tester for leaks in and around the unit.
If there is no problem with the vehicle, you can drive it at highway speed for 30 minutes. This will raise the exhaust temperature sufficiently to allow the vehicle to regenerate. You can achieve the same result if you don’t have this option by running your engine at highway speed for approximately 30 minutes.
If the problem persists, it is best to bring the vehicle to a workshop. You can see whether the vehicle is in the regeneration phase by looking at the signals coming from the ECU or sensors.
NOTE: Certain modifications, such as cat-back exhaust or cold air intake (CAI) kit kits, may trigger this code. This could also affect your warranty.
