6.2.3. Check and replacement of the sensor of temperature of the engine

The sensor of temperature takes temperature of the engine and reports it to ECM. The sensor contains an element which resistance decreases with a growth of temperature. If value of temperature reaches some lower bound, the error message 14 follows; at excess of the upper bound the mistake 15 is displayed. ECM in this case as spare value uses OZh temperature equal the 80th hail. This value corresponds to the warm engine and at low ambient temperatures and the cold engine leads to problems of start and uneven operation of the engine.

That at removal of the sensor cooling liquid did not follow, previously merge a part of liquid.


 PERFORMANCE ORDER

  1. Separate the socket of an electrical wiring of the sensor of temperature of the engine and turn out the sensor from the inlet pipeline.

Location of the sensor of temperature of the engine

On the 82 h.p. engine of 1.4 l the sensor is screwed in a head of cylinders under DIS ignition module. On l DOHC 1.4 and 1.6 engines the sensor is from a gear belt of the GRM drive.

  1. Measure electric resistance between contacts of the sensor and compare the received values to requirements of Specifications in the Head of the Power supply system, release and decrease in toxicity of the fulfilled gases.

  1. If resistance does not conform to requirements of Specifications in the Head of the Power supply system, release and decrease in toxicity of the fulfilled gases, replace the sensor.
  2. If the sensor is serviceable, screw it with a new sealing ring with effort of 20 Nanometers.
  3. Include ignition and measure tension between contacts of the sensor. It has to make 5 ± 0.1 Century. If tension is absent, check an electrical wiring according to the electric circuit (see the Head Onboard electric equipment).
  4. If the electrical wiring and the sensor are serviceable, means ECM is faulty.
  5. Fill the cooling system and remove from it air (see the Head of the Cooling system of the engine, heating of salon and air conditioning).
  6. Make a small trip on the car and check connection of the sensor of temperature for leaks, if necessary bring up him a little.
