Oxygen sensors (O2S — Oxidant Sensor) – represent firm electrolit from ZrO — ceramics. At high temperature this electrolit becomes electrocarrying out and generates a characteristic galvanic charge which is an indicator of the content of oxygen in the fulfilled gases.
The sensor of provision of a cranked shaft (CKP — Crankshaft Position Sensor) – hands over PCM information on situation and frequency of rotation of a cranked shaft.
The sensor of provision of a camshaft (— Camshaft Position Sensor) on models since 1998 of release develops CMP impulses, on the basis of which PCM identifies the first cylinder and time of opening of a nozzle.
The sensor of a toplivovozdushny mix (A/F Sensor — Air/Fuel Sensor) on models since 2001 is established in the top part of catalytic converter and works similar to the oxygen sensor.
The sensor of temperature of cooling liquid (ECT — Engine Coolant Temperature) supervises temperature of cooling liquid, and, on the basis of a PCM sensor signal, changes an air and fuel ratio in mixes, a corner of an advancing of ignition and puts in action system of a retsirkulyatsiya of the fulfilled gases (EGR).
The sensor of temperature of air arriving in the engine (IAT — Intake Air Temperature) on models till 2001 hands over information on temperature of air arriving in the engine. PCM on the basis of received information operates a fuel stream, changes a corner of an advancing of ignition and puts in action system of repeated burning of the fulfilled gases (EGR).
The sensor of provision of a butterfly valve (— Throttle Position Sensor) hands over TPS information, on the basis of which PCM defines, when the butterfly valve is closed, completely open or is in intermediate provisions.
The sensor of absolute pressure (MAP — Manifold Absolute Pressure) on models till 2001 measures amount (volume) of the air arriving in the engine in an inlet collector.
The sensor of a measuring instrument of a consumption of air (MAF — Mass Airflow Sensor) on models since 2001 measures mass of the air arriving in the engine.
The sensor of speed of the car (VSS — Vehicle Speed Sensor) measures and hands over PCM information on instant speed of the car.
The sensor of control of pressure паров fuel (Vapor Pressure Sensor) is used for pressure control паров in catching system паров fuels. PCM, on the basis of received information, operates vacuum valves (VSV) in catching system паров fuels.
The switch of the amplifier of a steering (PSP — Power Steering Pressure) is used for increase in frequency of rotation of idling when maneuvering car.
Transmission sensors. In addition to the sensor of speed of the PCM car receives information from the following sensors in a transmission: sensor of frequency of rotation of the coupling of coupling and sensor of speed of the car.
