Oxygen sensors (O2S — Oxidant Sensor) – represent solid electrolyte from ZrO — ceramics. At high temperature this electrolyte becomes electroconductive and generates a characteristic galvanic charge which is an indicator of content of oxygen in the fulfilled gases.
The sensor of provision of a bent shaft (CKP — Crankshaft Position Sensor) – tells PCM information on situation and frequency of rotation of a bent shaft.
The sensor of position of the camshaft (CMP — Camshaft Position Sensor) on models since 1998 of release develops impulses on the basis of which PCM identifies the first cylinder and time of opening of a nozzle.
The sensor of fuel-air mix (A/F Sensor — Air/Fuel Sensor) on models since 2001 is installed 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) controls temperature of cooling liquid, and, on the basis of a PCM sensor signal, changes a ratio of air and fuel in mixes, a corner of an advancing of ignition and puts system of recirculation of the fulfilled gases (EGR) in action.
The sensor of temperature of the air coming to the engine (IAT — Intake Air Temperature) on models till 2001 transfers information on temperature of the air coming to the engine. PCM on the basis of the obtained information operates a fuel stream, changes a corner of an advancing of ignition and puts system of repeated combustion of the fulfilled gases (EGR) in action.
The sensor of provision of a butterfly valve (TPS — Throttle Position Sensor) transfers information on the basis of which PCM defines when the butterfly valve is closed, completely open or is in intermediate positions.
The sensor of absolute pressure (MAP — Manifold Absolute Pressure) on models till 2001 measures amount (volume) of the air coming to the engine in an inlet collector.
The air consumption measuring instrument sensor (MAF — Mass Airflow Sensor) on models since 2001 measures the mass of the air coming to the engine.
The car speed sensor (VSS — Vehicle Speed Sensor) measures and transfers PCM information on the instantaneous velocity of the car.
The sensor of control of pressure of vapors of fuel (Vapor Pressure Sensor) is used for control of pressure of vapors in system of catching of vapors of fuel. PCM, on the basis of the obtained information, operates vacuum valves (VSV) in system of catching of vapors of fuel.
The switch of the amplifier of steering (PSP — Power Steering Pressure) is used for increase in frequency of rotation of idling when maneuvering the car.
Transmission sensors. In addition to the sensor of speed of the PCM car obtains information from the following sensors in the transmission: sensor of frequency of rotation of a clutch coupling and sensor of speed of the car.
