exhaust gas recirculation (EGR — Exhaust Gas Recirculation) was created in the early 70's, and today brought to a high level of perfection. The main objective of EGR system does not provide for the improvement of the technical characteristics of the engine, and in fact set of environmental considerations (Euro 2, Euro 3, Euro 4 and Euro 5).
The EGR valve in place
Cars Honda family equipped with an electronic system of gas recirculation. The work of the EGR valve is controlled by an electronic control unit (ECU or ECU — Electric Control Unit). Based on the testimony by the internal combustion engine sensors and complex arithmetic and logic calculations going management and control of the height of the EGR valve stem to obtain the desired proportions of recirculation of exhaust gases at the right time. Feedback is done by reading the level of resistance of the potentiometer also known as the stroke position sensor (VPS).
EGR valve Six-connector
Use of this system in Russia has a lot of specifics. It's no secret, the quality of fuel in our country is quite low. Sometimes frank counterfeit, which can stumble on any (even the most prestigious) refueling. On average, in this situation the term EGR system service at best 50-70 thousand kilometers. Poor-quality fuel leads to the fact that the EGR valve is covered with carbon deposits, and ceases to function properly.
Sample Valve clogging
Over time, the coke prevents the valve tightly closed violates mobility stem oxide "tracks" on the potentiometer.
The damaged layer rezistyvny potentiometer sensor
Eventually valve in any position of wedges (!), Which in turn adversely affects the operation of the engine. The symptoms are different: difficult to start the engine in the "cold"; transient increase idle speed; unstable operation of the XX on "bottoms"; "Floating" speed; when you press on the gas pedal the engine speed will rise with a delay, there may be "gaps"; jitters at idle; jerking when accelerating; uneven acceleration. Usually accompanied by refusal EGR "CHESK th" on the dashboard. During the fault diagnostics, the corresponding error pack (12- *, P0401 (80- *), P1491). It is clear that the conventional "reset" the problem is not solved.
Valve EGR — an expensive item, so many motorists, instead of replacing it resorted to "dancing with a tambourine" by various means of cleaning soot and tries to restore the damaged layer resistive potentiometer ordinary graphite pencil. The apparent confusion comes at the opening of the valve and the intake manifold.
Example of carbon deposits clogging the intake manifold
Example 2 carbon deposits clogging the intake manifold
Complete blockage of the internal vacuum manifolds and intake manifold of the valve carbon deposits. After playing, jamming accepted throughout the EGR means for laying out of cans of Coca-Cola, vytachivaniem own "caps" or spacers under the valve, disconnect the 6-pin connector or no go "as is". Just stop it will not correct the air-fuel mixture, the temperature rise in the combustion chamber, and opportunities are often short-detonation. The consequence of these experiments will be clogged intake manifold and costly repairs.
Of course, you can "flash brains" of 10 thousand rubles, and in software disabled, but for that matter, few takes. Usually remove error display on the instrument panel.
This is a problem encountered and my comrade Sergei (
TashMaster). Having studied the service manual and realizing operation algorithm has been previously submitted
the second version of the emulator .
The very first version squander a negative voltage of a number of sensors due to mistakes of the previous Developer scheme. Then for some reason he had to abandon the integration of the emulator in a broken valve by mounting directly to the inside in the resistance potentiometer replacements. Not everyone has the power to carry out work of this kind.
After a series of changes and improvements introduced in this article, the fifth revision ( EGR_rev.5 ) is different from the previous ones by the following parameters:
— Dimensions reduced to the size of a 6-pin connector;
— The case is completely closed from any external influences (any liquids and oil, sand, soot, temperature difference);
— Expensive Italian contacts (from a special alloy) allow to keep good contact;
— The sensitivity and speed of withdrawal of the emulator is higher than the original sensor (ECU adjusts stehiometricheskoge ratio strictly prioritized lambda probe).
Presented emulator will allow you to forget the terrible word EGR. The emulator runs on a logical level and emulates exact "behavior" at the EGR valve "Communion" with the computer.

Intensive Riding on the Ring Road st.
You can buy a pad (18715-PB2-000), the cap (18711-PM1-J00) and to muffle muffled as did Sergei (and many of Hondavodov), but it is not required. It is mandatory to tightness of the cap rod relative to the valve seat.
Note the seat stem relative to the valve seat
To do this, remove the EGR valve and inspect the work surface carefully. In the case where the valve is already "tired" and seen obvious coke deposits on the rod or jammed condition, it is best to drown out the still muffled. If there are no coke deposits on the rod and you are sure there are no air leaks — safely remove the valve six-pin connector and the same connector connect the emulator. In this procedure the EGR valve stub ends.
The basic meaning of "turn off" the real EGR valve is to exhaust waste gases do not fall back into the inlet and do not contaminate the carbon deposits vacuum manifolds intake manifold and the cylinder group.
