The sensors are «hall sensors».
Information about the position of the camshafts comes from sensors in the engine ECU in the form of rectangular signals.
Based on this information, the engine ECU:
- synchronizes fuel injection in relation to the position of the pistons;
- recognizes top dead center;
- detects misfires
- determines the amount of lift inlet valves.
Features of electrical equipment
Each camshaft sensor has a 3-pin connector.
Connector pin assignment:
- channel 1 - power «+ V»;
- channel 2 - signal;
- channel 3 - «weight».
Emitted signal: presence of metal «masses» opposite the sensor - 0 V;
lack of metal «masses» opposite the sensor: 12 V.
