Malfunction elimination method
1
13
Sensor of temperature of cooling liquid
  – if the following code 23 or 33, you watch group 6;
  – if temperature of cooling liquid too low then to warm up the engine and and to repeat check;
  – to check connections of wires.

34
The sensor of temperature of the arriving air
  – to check connections of wires;
  – to check sensor resistance (between contacts of the socket of the electronic actuation device "25" and "46"):
at 20 °C: 35 – 40 Ohms;
at 40 °C: 15 – 18 Ohms;
at 60 °C: 7 – 8,5 Ohms.

15
Sensor of provision of a butterfly valve
  – if the following code 25 or 35, you watch group 7;
  – to check a condition of a cable of a pedal of an accelerator;
  – to check the sensor and its wires;
  – if malfunction is still present, then to replace the electronic EEC IV actuation device.

17
Sensor of absolute pressure
  – if the following code 25 or 35, you watch group 7;
  – to check vacuum in an inlet collector idling – has to make 400–600 mm Hg;
  – to check tightness of an inlet collector and pressure of compression;
  – to check tightness of the vacuum pipeline, accumulator and sensor.
5
21
Wrong signal of ignition of "PIP"
  – to check connections of wires of the electronic EEC IV actuation device;
  – to check resistance between contacts of the socket of the electronic actuation device:
"56" and "36" – 2–5 kOhm;
"16" and "40" – 0–2,5 Ohms;
between (+) the accumulator and the ignition coil – 0–2,5 Ohms;
  – to replace the ignition distributor;
  – to replace the electronic EEC IV actuation device.

23
Sensor of temperature of cooling liquid
  – to check a state and connection of the socket;
  – to check sensor resistance:
at 20 °C: 35–40 Ohms;
at 40 °C: 15–18 Ohms;
at 60 °C: 7–8,5 Ohms
  – to check a plait of wires;
  – to replace the sensor;
  – to replace the electronic EEC IV actuation device.

Sensor of provision of a butterfly valve
  – to check the socket;
  – to check functioning of a butterfly valve and a cable of a pedal of an accelerator;
  – to check resistance between contacts of the socket of the electronic actuation device:
"26" and "46" – 315–550 Ohms;
"47" and "46" – 1,2–2 kOhm;
"26" and "47" – 3,5–5,5 kOhm
  – to check electric wires;
  – to replace the sensor;
  – to replace the electronic EEC IV actuation device.

Sensor of absolute pressure
  – to check the socket;
  – to check a condition of the vacuum pipeline and also whether it is original;
  – to check vacuum in an inlet collector idling – has to make 400–600 mm Hg;
  – to check electric wires;
  – to replace the sensor;
  – to replace the electronic EEC IV actuation device.
