The scheme of an arrangement of components of control systems of engine/decrease in toxicity of the fulfilled gases in an impellent compartment of the V6 models

1 — the Detector of control of electric loadings (ELD) (under the assembly block of safety locks)
2 — the Valve of system of operated ventilation of a case (PCV)
3 — the Sensor of absolute pressure in the pipeline (MAR)

4 — the Sensor of provision of a butterfly valve (TPS)
5 — the Valve of system of a retsirkulyatsiya of the fulfilled gases (EGR)


For the purpose of decrease in level of issue in the atmosphere of the toxic components getting to composition of fulfilled gases of the engine as a result of evaporation and incompleteness of combustion of fuel, and also for maintenance of efficiency of return of the engine and the decrease in fuel consumption considered in the real Management cars are equipped with a number of special systems which could be united under the general name of control systems of the engine and decrease in toxicity of the fulfilled gases.

It is necessary to carry the following to number of the systems concerning management of operation of the engine and control of toxicity of the fulfilled gases:

a) System of onboard diagnostics (OBD);
b) System of electronic control by the engine (PGM-FI);
c) Detector of control of electric loadings (ELD);
d) System of a retsirkulyatsiya of the fulfilled gases (EGR);
e) System of catching of fuel evaporations (EVAP);
f) System of operated ventilation of a case (PCV);
g) Catalytic converter.

Functioning of all listed systems, anyway, directly or indirectly, is connected with management of decrease in toxicity of the fulfilled gases.

In the Sections provided below the general descriptions of principles of functioning of each of systems are given, and also procedures of diagnostic checks and regenerative repair (if that is obviously possible) components of the systems which performance lies within qualification of the average amateur mechanic are stated.

Before coming to conclusion about refusal any of systems of decrease in toxicity, attentively check serviceability of functioning of power supply systems and ignition (see. Heads of the Power supply system and release and engine Electric equipment). Diagnostics of systems of decrease in toxicity some of knots demands use special, difficult in application, the equipment and a certain qualification of the performer, and therefore, it will be reasonable to charge its performance to professional mechanics of specialized car repair shop.

Told does not mean above that service and repair of components of systems of decrease in toxicity in practice are represented exigeant. Do not forget that one of the most widespread causes of failures is elementary violation of quality of vacuum or electric connections, and therefore, first of all always it is necessary to check a condition of shtutserny and electric sockets. The owner of the car can independently and it is rather simple to make a number of checks, and also, to execute in house conditions a set of procedures of routine maintenance of the majority of components of systems, using thus a usual set of the adjusting and metalwork tool. Remark: Do not forget about additional federal guarantee certificates under which components of systems of decrease in toxicity and management of operation of the engine get. Before starting performance of any procedures on repair of knots and details of data of systems, consult about conditions of observance of these obligations in representation office of the Honda company.

Try to observe everything the measures of precautions stipulated in below-mentioned Sections at performance of service of electronic components of considered systems. It is necessary to notice that the illustrative material can correspond not always in accuracy to real placement of components on the car. Such discrepancies are connected with continuously occurring process of updating within a standard design of each model.

In an impellent compartment of the car information label of systems of decrease in toxicity of the fulfilled gases (VECI) is fixed. On a label necessary information on settings and checks of under control systems taking into account all updatings made on the concrete car, and also the scheme of laying of vacuum hoses with identification of various components contains. Before starting service of systems of decrease in toxicity and management of operation of the engine, attentively familiarize with VECI data.
