272E00 Exhaust gas recirculation actuator high pressure, position control:mechanically defective near close position

Fault code 272E00 Exhaust gas recirculation actuator high pressure, position control:mechanically defective near close position store in engine control module is related to the problem with exhaust gas recirculation valve. Exhaust gas recirculation valve is use to return a small part of burn gas back to engine’s combustion chambers through intake manifold. This process is controlled by an actuator which is used to install on the top of exhaust gas pipe. This actuator is control by engine control module according to the requirement of engine. Like there is a requirement of boosting engine or high torque than exhaust gas recirculation valve open by engine control module.

Engine control module receive different information of engine from different signal in the form of voltage. When all the signal from different sensor give signal to open exhaust gas recirculation valve than engine control module open exhaust gas recirculation valve. But after driving certain kilometer high amount of carbon deposition take place at the opening of exhaust gas recirculation valve. Due to which when engine control module give signal in the form of voltage to exhaust gas recirculation valve it does not open. When this kind of problems occurs at the actuator it send signal back to engine control module about position of valve. Than engine control module set fault code 272E00 Exhaust gas recirculation actuator high pressure, position control: mechanically defective near close position store in engine control module.

Causes 272E00 Exhaust gas recirculation actuator:

Block exhaust gas recirculation valve from carbon deposition.

Faulty sensor of exhaust gas recirculation valve.

Damage wiring harness of the EGR actuator.

Blown fuse of exhaust gas recirculation valve.

Loose contact at the connector of exhaust gas valve.

Failure of any other sensor which is disturbing the signal of sensor.

Symptoms of 272E00 Exhaust gas recirculation actuator:

Check engine light will illuminate on cluster meter.

Engine power will drop while driving.

Pick up issue while driving at hill side road.

Low mileage problem due to irregular mixture of air fuel ratio.

How to trouble shoot:

When found this 272E00 Exhaust gas recirculation actuator high pressure, position control:mechanically defective near close positionis store in engine control module. You need to check opening and closing position of the exhaust gas recirculation valve with the help of scan tool. If exhaust gas recirculation valve does not open of close completely than go to check the reason behind this.

First thing is to do in this situation is to check fuse of exhaust gas recirculation valve if there is any. Because sometime it is directly control by engine control module. If found blown fuse than replace that faulty fuse with new one. If fuse if good than to go to check valve of exhaust gas recirculation valve for carbon deposition on it. Remove exhaust gas recirculation valve outside engine and check carbon deposition on it. If there is carbon at the opening of valve which doesn’t allow valve to open properly. Than clean that carbon with carbon cleaning agent so that it clear all the carbon properly.

But if there is no carbon on the face of valve than check wiring harness of the sensor with the help of multimeter. If there is something on the connector of the actuator sensor. Than check the reason behind that like if there is no power supply than check blown fuse of power supply, if ground is not present than check ground wire if it is damage from somewhere. If all the power supply, signal and ground is present on the connector than check condition of the sensor. If there is any doubt of the actuator than replace that actuator so that problem can be solve.

When all the power supply is present and valve actuator is also good there is not fault at actuator. Than in this situation it might be possible that there is some other sensor is faulty. Due to which is disturbing the signal of EGR actuator. With the help of scan tool check signal of the other sensor if found any error in any sensor signal than replace that sensor. Most of the time in this problem failure of air mass sensor is the main reason.

What repair can fix 272E00 Exhaust gas recirculation actuator:

Clean carbon deposition on the valve of exhaust recirculation valve.

Replace faulty sensor of exhaust gas recirculation valve.

Repair damage wiring harness of the exhaust gas recirculation valve.

clean contack of connector at the socket of exhaust gas recirculaation valve.

Replace any other faulty sensor which is disturbing the signal of exhaust gas recirculation valve.

Replace blown fuse of exhaust gas recirculation valve.

Common mistake while solving 272E00 Exhaust gas recirculation actuator:

Most of the time when this fault code is store in engine control module. Mechanic does not understand the meaning of fault code due to low experience of work. They take this fault as failure of exhaust gas recirculation valve actuator. They change that actuator but did not able to solve the problem because that is not thing which is faulty. Do not replace the any part whitout proper diagnosis, because it can take you a very expensive repair.

Equipments you need to complete this work:

A scan tool either OEM or any other after market product.

Test light to check fuse.

Multimeter to check voltage at the connector of the exhaust gas valve actuator.

Tools box to open exhaust gas recirculation valve.

Carbon cleaning agent to clean valve of exhaust gas recirculation.
