244b00 charge air pressure control low

Fauclt code 244b00 charge air pressure control low pressure stage control deviation : charge air pressure too high is a problem related with drive train issue.  Charge pressure sensor is use to monitor pressure and convert them into electrical signal ,and send this signal to engine control module.This could be happen due to low pressure of air intake into combustion engine. There is a sensor on up stream of turbo known as exhaust gas temperature sensor. Whenever there is a problem of low pressure of air occurs. Engine control module set fault code 244b00 charge air pressure control low pressure stage control deviation.

 244b00 charge air pressure control

Causes of 244b00 charge air pressure control :

  • Faulty charge pressure sensor.
  • Carbon deposition on intake manifold.
  • Leak at vacuum pipe.
  • Block exhaust gas recirculation valve.
  • Block diesel particulate filter.
  • Leak at diesel particulate filter.

Symptoms of 244b00 charge air pressure control :

  • Drive train fault will start blinking on cluster meter and also on display.
  • Loss of power at high speed or high rpm.
  • Fault code will store in engine control module.

How to trouble shoot :

  • When found drive train fault on cluster meter or at display stop vehicle and check problem why this is happening. Hook scan tool and scan vehicle to find out fault code due to which there is a drive train malfunction. When found fault code 244b00 charge air pressure control low pressure stage control deviation store in engine control module. Than it means that there is some problem at air intake area. Which can be anything like leak at vaccum pipe, block exhaust gas recirculation area, carbon deposition on intake manifold runner,block diesel particulate filter, faulty charge pressure sensor.
  • Check everything one by one as there could be problem of any one thing only. Like if there is carbon deposition on exhaust gas recirculation valve. Due to which exhaust gas recirculation valve is not opening as per the requirements of engine.
  • The second things that can be the reason behind this, is vacuum line of exhaust gas recirculation system. To confirm that there is a problem of vacuum line replace all vacuum line. Now all problem should gone, but if still there is problem. It means that there is some other problem due to which there is a fault code drive train.
  • Now remove exhaust gas recirculation valve check carbon deposition there, if there is carbon deposit than clean that. Also check throttle control valve and intake manifold for carbon deposition. Clean all the carbon deposit at exhaust gas recirculation valve and intake manifold runner or throttle control valve.
  • The other thing to check in this situation is block diesel particulate filter. Check diesel particulate filter for leak at seals, if there is leak at seals than replace all the seals and again check if there is any leak at seals. If there is no leak at packing area than also there could be fault of charging pressure sensor than replace charge air pressure sensor.
  • After replacing charge pressure sensor there should be no fault code. Take a long distance test drive after replacing sensor. Look if there is drive train fault still blinking on cluster meter or centre display.
  • If still drive train fault code is present in system than it means that there is some issue inside diesel particulate filter. Replace diesel particulate filter to solve problems of drive train issue. After replacing diesel particulate filter take a lond test drive now there should be no fault code or warning light on cluster meter or center display. As now everything which is related to the fault code charging pressure control, control deviation: charging pressure too/low positive control deviation is been check and replace. Thats why now there should be no fault code or drive train warning on cluster or center display.

Solution :

  • Replace leak vacuum pipe line.
  • Clean exhaust gas recirculation valve or intake manifold.
  • Repair damage wiring harness.
  • Replace faulty charge pressure sensor.
  • Replace blocked diesels particulate filter.
