8.2.4. The gauge of position throttle заслонки (ДДЗ)

THE GENERAL DATA

The gauge of position throttle заслонки (ДЛЗ)

1. THE GAUGE OF POSITION THROTTLE ЗАСЛОНКИ 2. THROTTLE ЗАСЛОНКА

ДДЗ represents a potentiometer which is established in the case throttle заслонки and it is connected with its axis. Conducting ДДЗ includes a wire of a food with pressure 5 In, "mass" and alarm wires. On pressure of a signal of DDZ ECU defines current position заслонки. At influence on a pedal of an accelerator signal ДДЗ in appropriate way changes. At closed throttle заслонке pressure of a signal makes about 0,5 V.Po to an opening measure заслонки pressure of signal ДДЗ grows and at completely opened заслонке makes about 5 Century ECU doses out giving of fuel depending on a corner of opening throttle заслонки which is defined by operating influence of the driver. Rupture or easing of contacts of wires can lead to non-uniform giving of fuel in engines and unstable work of the engine idling, as ECU принима ет astable signal ДДЗ for a sign of movement throttle заслонки. At refusal ДДЗ or conductings ECU establishes a code of malfunction 21. After that ECU ignores signal ДДЗ – engine work improves. At installation of a code of malfunction 21 high frequency of idling of the engine is supported.

To remove or disconnect

PERFORMANCE ORDER

1. An electric socket. 2. Fixing screws and fixing washers. 3. The gauge.

To establish or attach

PERFORMANCE ORDER

1. To close throttle заслонку and to establish in its case DDZ. 2. To screw two fixing screws. To tighten screws of fastening ДДЗ the moment of 2 Nanometers. The prevention By means of the scanning device to check up pressure of signal ДДЗ at completely closed заслонке. Pressure of a signal should not exceed 1,25 Century Otherwise (pressure above 1,25) to check up presence of jamming of an axis throttle заслонки or рычажка ДДЗ. If it was not possible to find out a cause of defect, to replace ДДЗ. 3. An electric socket.
