System of recirculation of the carried out gases (EGR) – the general information, check of a state and substitution of component ones

General information

For aims of the reduction in the question in the atmosphere of oxide of the nitrogen a part of the carried out gases returns to the entry oil pipeline he was seeing the valve EGR. Such a mixture of the gases carried out to the mixture of air fuel drives to lessen in the temperature of his combustion.

The system is composed of the valve EGR, the valve eletromagnética of the management of EGR (only it is in use in some models), the sensor of the opening of the valve EGR and the module of the management (ECM/PCM). ECM/PCM is planned so that it supplies the best point of the opening of the valve EGR of any operational condition of the motor. The sensor of special information constantly draws the point of the opening of the valve EGR, giving the corresponding signs in the module of the management. ECM/PCM compares the information on entry with the data that arrive of other sensors and, in case of the necessity it does the given agreement of the depth of the depression in the valve EGR he was seeing the valve eletromagnética of the management.

To check

The models are equipped of CVT

ORDER OF REALIZATION

1. The motor begins and heat it up to the temperature of normal work (the supporter of the system of cooling has to be lit). 2. Desconecte a hose of vacuum of the valve EGR and join the measure of vacuum. 3. The depression has to be going away if this condition is satisfied, I pass to artistic proceedings of the paragraph 5. 4. If the depression happens, disunite the capture of the valve eletromagnética of the management of EGR and again check the existence of the depression in the valve EGR. To find the valve eletromagnética, walk in a hose of vacuum of the valve EGR. If the depression if it is going away, expels the car in the workshop of repairs of the car to execute the diagnostic one of ECM/PCM with the use of the special reader (to see the Check of usefulness of a state and substitution of the sensor of VMT/provision of a doubled end / the situation of pistons in cylinders of the motor (TDC/CKP/CYP)). In the presence of the depression they check the fairness of the placing of lines of vacuum. If the hoses as debit to be, substitute the valve eletromagnética. 5. If the depression was not of the same beginning, adhere to bomb of manual vacuum to the valve EGR and create the depression of 203 mm of mercury to bottom. – the motor will decline. Also check the capacity of the valve of maintaining the depression if such a capacity if it is going away, substitutes the meeting. 6. Check the presence of the tension of the battery in the valve eletromagnética of the management of EGR. Disunite the capture of 2 contacts of the valve and they join the voltômetro between the positive capture of the capture of the main braid (the capture of a red wire) and I weigh. The battery tension has to happen. 7. Join the measure of vacuum to a hose of vacuum of the valve EGR and the motor begins in the only turns. Through a point of passage of wire they join the positive capture of the battery to the capture of a red wire of a reverse side of the capture of a braid. Looking at indications of the measure of vacuum, it fuses the second capture of the capture of 2 contacts through the second point of passage of wire. The depth of the depression will increase inside a second (the sound of the operation of the valve eletromagnética has to be heard). If the depression if it is going away, substitutes the meeting of the valve EGR eletromagnética. 8. The most detailed diagnostic one of the system demands the use of the special reader and has to become in the conditions of a workshop of the service of the car.

Models with RKPP

ORDER OF REALIZATION

1. The motor begins and heat it up to the temperature of normal work (the supporter of the system of cooling will work). 2. Disunite the capture of 6 contacts of the valve EGR and they secure the tension of available battery between captures of pink and black wires of the main braid of an electrical system. If the tension if it is going away, checks a pink wire in the siege between the valve and ECM/PCM of existence of signs of the interval and weakening of the fixation of connections of contact. Also check the confidence of the base of a black wire. If an electrical system as debit to be, the car has to be expelled in the workshop of repairs of the car of the detailed diagnostic one of ECM/PCM. 3. If the tension of the battery happens, kill the motor. Through a point of passage of wire they join the positive capture of the battery to the capture of a pink wire of the capture of 6 contacts of an electrical system of the valve EGR/sensor of the point of his opening. The motor begins in the only turns and through the second point of passage of wire they establish the capture of a black wire of the capture. The turns stability of wasting time has to be broken agudamente, up to a motor stop, otherwise to substitute the meeting of the valve / sensor. If no modification in the operation of the motor happens, there checks an electrical system the interval and the confidence of the fixation of connections of contact. 4. The most detailed diagnostic one of the system demands the use of the special reader and has to become in the conditions of a workshop of the service of the car.

Substitution of component ones

Valve of EGR

ORDER OF REALIZATION

1. Desconecte an electrical system of the sensor of the opening of the valve EGR. Desconecte a vacuum hose. 2. Give two nuts of fixation and withdraw the valve EGR of the oil pipeline of entry. 3. Smooth the inter-connected surfaces of the valve and his transitional mouth. 4. Substitute the placing of fighter and install the valve EGR at the regular place. Strongly hold tight nuts of fixation. 5. Restore the initial connection of an electrical system.

The valve eletromagnética of management of EGR (only model with CVT)

ORDER OF REALIZATION

1. Having transmitted a hose of vacuum of the valve EGR, find the valve eletromagnética of the system management. Desconecte an electrical system and inhale hoses, result fixation screws and withdraw the valve. 2. The installation is done upside-down.
