2.7.7.11. Conditions of storing of codes of malfunctions

EBU brings the P0116 code in memory and includes a control lamp of malfunction of a control system of the engine if the actual performance data of the sensor during 0,2 with is in two cycles of driving more than 20 °C below than the EBU mode curve (determined by amount of the given fuel, the surrounding temperature and operating time of the engine). This code indicates the uncharacteristic size of temperature of cooling liquid given by the sensor of temperature of cooling liquid or EBU. EBU gives the P0117 code and includes a control lamp of malfunction of a control system of the engine if during 0,2 with in two cycles of driving value of temperature below -45 °C gives the sensor of temperature of cooling liquid.
EBU gives the P0118 code and includes a control lamp of malfunction of a control system of the engine if during 0,2 with in two cycles of driving the sensor of temperature of cooling liquid gives value of temperature above 140 °C.

NOTE
Resistance of DTOZh changes depending on temperature as follows:
– 5900 Ohms at 0 °C;
– 2500 Ohms at 20 °C;
– 300 Ohms at 80 °C.

Check
Remove the sensor of temperature of cooling liquid from the inlet pipeline.

Fig. 2.243. Check resistance of the sensor of temperature of cooling liquid


Check sensor resistance, having shipped its sensitive element in hot water (fig. 2.243).
At resistance deviation from norm replace the sensor.


Installation
Apply on a carving part of the sensor LOCTITE 962T sealant or similar.
Wrap the sensor of temperature of cooling liquid and затянитеь its specified moment.
Moment of an inhaling of the sensor of temperature of cooling liquid: 15–20 N · m.
