The VTEC systems – the general information and check of a condition of components
Many of models of the Honda cars are equipped with electronic system of correction of phases of gas distribution (VTEC).
Distinction between the ordinary engines and engines equipped with the VTEC system consists in a complete set and the principle of operation of the valvate mechanism. A design of the block of the engine and all hinged knots and units, and also schemes of the organization of lubrication systems and cooling on both units are identical. The engine which is externally equipped with the VTEC system differs in existence from above on a cover of a head of cylinders of a convex inscription of the corresponding content (VTEC).
The inlet camshaft is equipped with three cams for each of the valves given by it. The special module of management of the power (RSM), proceeding from the data arriving from information sensors defines what of sets of cams has to bring inlet valves of combustion chambers into each present situation. On the basis of the analysis of the arriving information of RSM includes or switches off the VTEC system.
As the initial parameters defining functioning of VTEC the following is used:
a) Frequency of rotation of the engine (rpm);
At small turns of the engine both primary, and secondary inlet valves work from own cams and open on identical height and with an identical duration, providing good torque in the lower range of turns and the high speed of reaction to gas.
When there is a need for increase in return of the engine, yokes of primary and secondary inlet valves by means of the special hydraulic device with electronic control are blocked with an intermediate yoke. At the same time duration and height of opening of both valves is defined by a form of the intermediate cam differing in the bigger height and smaller pointedness of rise.
Check of a condition of components
Electromagnetic valve of blocking / датчик-выключатель pressure
The electromagnetic valve of blocking of the VTEC system including the sensor switch of pressure is located in the left part of a back wall of the engine (from a partition of a motive compartment).
Models 1994 and 1995 of of the issue.
Malfunctions in a contour of the electromagnetic valve of blocking of VTEC lead to registration of a code of malfunction (DTC) 21 in memory of the control unit. On the car dashboard at the same time the control lamp "Lights up check the engine". Detailed information on DTC systems of self-diagnostics are provided in the Head of the Control system of the engine.
The failure of the sensor switch of pressure leads to the record DTC 22 and operation of a control lamp "Check the engine".
Models since 1996 of the issue.
The refusal in contours of the electromagnetic valve or sensor switch of pressure leads to operation of a control lamp "Check the engine" and records in memory of the DTC P1259 control unit. Reading of diagnostic codes requires the OBD II scanner (see the Head of the Control system of the engine).
