Diesel particulate filter is attached to diesel engine for the purpose of removing shoot and diesel particulate matter from exhaust gases. Fault code 245700 Particulate filter heavily clogged store in engine control module when the diesel particulate filter is heavily block. when diesel particulate filter is heavily block it reduce the power of engine while driving at high speed. while driving at high speed there is a warning indicator “Drive Train fault” on display. Also block diesel particulate filter reduce fuel efficiency of vehicle. When diesel particulate filter is block there will be some other fault code in engine control module which are similar to this fault code as they are belong each other.
Like faulty air mass sensor, low efficiency of exhaust gas recirculation cooler and also block exhaust gas recirculation valve. As when diesel particulate filter get block it stop passing burn gas due to which burn gases of combustion engine get trap in the system. To get out of this problem you need to regenerate diesel particulate filter so that clogged diesel particulate filter get free to pass exhaust gas. After regenarating diesel particulate filter there should be no fault code (245700 Particulate filter heavily clogged) or any other fault which are related to this fault code in engine control module.
Causes of 245700 Particulate filter heavily clogged:
- Clogged diesel particulate filter.
- Faulty charge air pressure sensor.
- Clogged exhaust gas recirculation valve.
- Also lock intake manifold.
Symptoms of 245700 Particulate filter heavily clogged :
- Warning indicator of drive train fault on cluster meter and center display.
- Pickup problem at high speed like 100-120 km/h.
- Also fault code will store in engine control module.
How to trouble shoot :
- When there is warning indicator ”Drive tarin fault” on cluster meter or center display stop vehicle and check if there is some fault code is showing on center display. If drive train fault is coming at high speed like 100-120km/h. Than it might be possible that there is some problem at EGR, turbo or vaccum line which are involve in vehicle power up process. To solve this kind of problem you need to scan vehicle with the help of scan tool. A highly skilled mechanic need to find the problem behid this and solve it.
- Scan vehicle with scan tool check all the fault code store in engine control module. If there is fault code 245700 Particulate filter heavily clogged store in engine control module. In this situation you need clear clogged diesel particulate filter. This process can be perform with the help of scan tool by performing regeneration of diesel particulate filter.
- Performing diesel particulate filter cleaning process is not a easy process. As it require a highly skilled technician to perform this procedure. You can read all the direction of performing cleaning diesel particulate filter (Regenaration of diesel perticulate filter) in scan tool. Follow that instruction to perform regeneration of diesel particulate filter process. After performing regenaration of diesel particulate filter you need to scan vehicle and check there should be no fault code (245700 Particulate filter heavily clogged) store in engine control module.
- In this situation there might be some other problem at engine like block exhaust gas recirculation system. Clean exhaust gas recirculation system to power up the engine. Along with exhaust gas recirculation valve remove intake manifold and clean it as well.
- Also in this situation there can be one other thing that is faulty charge air pressure sensor. Before cleaning diesel particulate filter check that charge air pressure sensor. If it require to replace that charge air pressure sensor than replace that. Still if there is some fault code present in the engine control module of about faulty charge air pressure sensor. after replacing that charge air pressure sensor fault code of clogged diesel particulate filter should not be present. But if fault code of clogged diesel particulate filter is still present in the system. Than cleaning diesel particulate filter is necessary to remove fault code from engine control module or warning light on center display.
Another mathod :
The another mathod to clean diesel particulate filter can be perform by removing diesel particulate filter out from engine. Remove diesel particulate filter out side from engine, take it to the below water tap. Open tap and let the water get inside it than mix some acid to clean deposite particulate matter inside diesel particulate filter. Let it mixed properly wait for some time than clean it with water pressure. With this process you can clean it without scan tool which is low cost also to clean diesel particulate filter. Do not try it as it is not a professional suggestion to do for the purpose of clean diesel particulate filter.
Solution:
- Regenerate diesel particulate filter.
- Replace diesel particulate filter paking.
- Replace faulty charge air pressure sensor.
- Also if there is some other thing is faulty than replace that.
