7.5.1.5. A temperature-sensitive element of soaked up air
THE GENERAL DATA

The temperature-sensitive element takes temperature of soaked up air. This size together with a signal of the gauge of pressure of an inlet gas pipeline serves for the actuation device as a measure of quantity of soaked up air. A temperature-sensitive element of soaked up air is the NTC-resistor (NTC = negative temperature factor) which resistance decreases at rise in temperature.

THE ENGINE IN VOLUME OF 2,2/2,5 L

Removal


PERFORMANCE ORDER
Remove a temperature-sensitive element together with the tip (В17х1), for this purpose compress both lateral fixing clips (1).

Check

PERFORMANCE ORDER
1. Disconnect штеккер.
2. Check up an ohmmeter resistance of a temperature-sensitive element at various temperatures. The measured size is perfectly in order, if it is in admission limits + 5 % (Resistance of a temperature-sensitive element see the table).
3. If at measurements the temperature-sensitive element does not reach preset values it is necessary to replace it.

Installation

PERFORMANCE ORDER
1. Spread cable штеккер (socket).
2. Check up on defects or porosity a sealing ring of a round profile, if necessary replace it.
3. Insert a temperature-sensitive element together with a sealing ring of a round profile.
4. Squeeze out fixing clips outside until it distinctly (on hearing) will be fixed.
