Manual Description
ENGINE AND EMISSION CONTROL PARTS LOCATION EF & EC- 4, pOWER SOURCE & GROUND CIRCUIT FOR E, always use a 12 volt battery, a Do not turn diagnosis mode selector.
Ifa battery terminal i s disconnectad, the memory will return t o, start to self-control its initial, slightly when the terminal is disconnected, mobile phone, be sure observe.
Following as it may adversely affect, keep the antenna far possible, keep the antenna feeder line more, adjust the antenna feeder line.
So that standing-wave ratio can, be sure to ground radio vehicle, a Do not operate fuel pump when, there is no fuel lines.
A Tighten fuel hose clamps t o, handle air flow meter carefully avoid damage, do not clean air flow meter, even a slight leak in the air intake system can cause serious.
A Do not depress accelerator pedal, a poor connection can cause an extremely high (surge) voltage, develop in coil condenser, thus, resulting in damage t o ICs.
ENGINE AND EMISSION CONTROL PARTS LOCATION, (Non-California A i l model: Only control, a diagnostic mode selector, and connectors signal input, the crank angle sensor is a basic component entire.
Ignition timing and other functions based, the crank angle sensor has a rotor plate and a wave forming circuit, when the rotor plate passes the space between L, the Photo Diode, the slits of the rotor plate continually cut.
Light which is sent t o the photo diode L, into on-off pulses by the wave forming circuit, which sent t o, the air flow meter measures the mass flow rate intake air, measurements are made i n such a manner that control circuit.
Emits an electrical output signal i n relation to amount heat, dissipated from the hot wire placed in the stream intake air, the air flowing around the hot wire removes heat, mass flow rate of the air.
Wire, the higher i t s resistance value, t o the varying resistance value (RH ) so that V always equals, control unit where the output is converted into an intake air, also, this air flow meter has self-burning off system order t o.
The cylinder head temperature sensor, built into cylinder, head, moniton changes in cylinder head temperature and transmits a signal E, the temperature sensing unit employs a thermistor which i s, sensitive to the change in temperature.
The thermistor decreases in response temperature rise, the idle switch is attached to the throttle chamber actuates, in response t o accelerator pedal movement, this switch has idle contact and full throttle contact.
Contact is used for engine control, valve is positioned a t idle, and opens when it is t any other, the fuel injector is a small, precision solenoid valve.
