The Hall sensor on the VR6 engine is located in a forward part of a head of the block of cylinders. At normal work engine electronics on the basis of a signal from the sensor of the Hall defines the ignition moment for the first cylinder. If the signal is not received, in cylinders detonation regulation cannot be carried out. In this case detonation regulation is switched off and the moment of ignition is exposed with some delay to avoid a detonation.

Check of the sensor of the Hall carry out as follows.

VR6 engine:

- disconnect VN wires from the transformer of a high voltage and remove VN directing wires from the transformer;

- disconnect a shtekerny block ( fig. 216 , it is shown by an arrow) Hall sensor;

Fig. 217. Check of the sensor of the Hall on the VR6 engine. «1», «2», «3» — numbers of plugs of a shtekerny block

- connect the voltmeter to the plug "1" and to the plug "3" (fig. 217) of a shtekerny block of the sensor of the Hall. Tension should make at least 11,5 In;

- if it not so, address on HUNDRED.

2,0-liter engine:

Fig. 210. Elements of system of ignition on the 2,0-liter engine (with system of injection of Simos): 1 — VN wire, to a spark plug; 2 — the tip suppressing a radio noise; 3 — a protective cover; 4 — a cover of the distributor of ignition; 5 — a begunok of the distributor of ignition; 6 — a three-contact shtekerny block; 7 — a dustproof cover; 8 — the ignition distributor with the Hall sensor; 9 — an O-shaped sealing ring; 10 — a clamping lath; 11 — a bolt, 25 N · m; 12 — a spark plug, 30 N · m; 13 — a tip of a wire of VN, on a spark plug; 14 — a bolt, 20 N · m; 15 — the sensor of a detonation (G61); 16 — the transformer of a high voltage (N 152); 17 — the target cascade of the transformer of a high voltage (N157); 18 — the plug "15"; 19 — the plug "1"

- disconnect a shtekerny block 6 (see fig. 210 ) from the distributor of ignition 8;

Fig. 218. Check of the sensor of the Hall on the 2,0-liter engine

- connect the voltmeter between external plugs of a shtekerny block (fig. 218) . Tension should make at least 10,0 In;

- if it not so, address on HUNDRED.
