Throttle body (4A-FE, 5A-FE, 7A-FE)
Members of the body for throttle ¬ slonki. 1 - general view of the case Drosia ¬ selnoy valves, 2 - electrical connector housing for the throttle ¬ slonki, 3 - position sensor Drosia ¬ selnoy valve, 4 - Contact the maximal load on the engine (full throttle for ¬ slonki), 5 - movable contact 6 - control cam, 7 - contact mode of a normal idle speed (idle at the lowest speed).
Checking the engine
1. Check the throttle body for-slonki,
a) Check the smoothness leads ¬ let valve.
b) (4A-FE (AE92, AE95, AT171 and AT180)) Check the vacuum in the cross-channel and attach to the corresponding ¬ sponding holes (E, F, P) with thumb hot engine running and with appropriate throttle position (see table).
Opening degree of throttle opening
P * a level above the hole P
E * 2 Above the hole E
P * 2 Above the hole P

* 2: With a system of recirculation of exhaust gases tion,
(4A-FE (AE101 and AT190) and 5A-PE (AE110), 7A-FE (AE93 and AE102)) Check the vacuum in the through channel and attach to holes in the finger-stiyu running programs that drive.
2. Check the position sensor Drosia-selnoy flap.
(4A-FE (AE92, AE95, AT171 and AT180))
a) Disconnect the sensor connector and insert the flat probe thickness 0.60 or 0.80 mm between the adjusting screw lock and the throttle lever.
b) Using an ohmmeter measure the resistance between the corresponding pins of connector-forming the sensor (see table).
The gap between the screw-lock Drosia selnoy damper lever (the thickness of the probe): 0.60 mm

If ohmmeter readings are not correspond to the data given in the table, adjust or replace the sensor in lozheniyadrosselnoy flap.
a) Connect to the gauge on the position the throttle.
4A-FE (AT190 and AE101), 7A-FE (AE93 and AE102) a) Disconnect the sensor connector and insert the flat probe thickness 0.40 or 0.90 mm between the adjusting screw lock and the throttle lever.
If the resistance values ??do not correspond ¬ spond to the data given in Table ¬ face, adjust or replace ¬ dates snip throttle position, and c) Connect to the gauge on the position the throttle.
(5A-PE (AE110))
a) Remove the air filter hose ¬ p and the air filter cover:
• Disconnect the ventilation hose fuel tank;
• disconnect the sensor connector of the temperature of the inlet air;
• Loosen the hose clamp air filter ¬ Nogo;
• disconnect the two tabs on the air filter cover;
• disconnect the hose from the filter and the throttle body remove the filter with a hose.
b) Disconnect the sensor connector on the position the throttle.

since 1997), 7A-FE (AE115)) Throttle Position Sensor for ¬ slonki installed on the housing Drosia ¬ selnoy damper is used to op ¬ definiteness of the angle of its opening. When the throttle is fully closed, the output of "UTA" electron ¬ Nogo control unit receives voltage of 0.3-0.8 V. When you open the throttle voltage proportional increases in proportion to the corner of the opening of ¬ and ¬ sion in the floor open to furnish ¬ 3 ,2-4, 9 V. Based on these signals, the electronic control unit determines the conditions leniya ¬ ¬ motion of the machine and adjust the composition of the fuel-air mixture.
Check the voltage on the position sensor throttle.
a) Turn the ignition key.
b) Move to the depression mechanism priotkryvaniya throttle.
c) Measure the voltage between the water you ¬ "UTA" and "E2" elec ¬ tronic terminal control unit, while the throttle will open in ¬ Det wholly-covered position.

Note: The voltage should increase gradually in proportion to the opening angle.
With the banning of the sensor ¬ start electronic control unit determines whether the trans ¬ mission in positions "P" and "Y", or in other positions. The signal conditioner you ¬ klyuchatelya serves to inform the electronic control unit and allows it to increase if necessary Chiva ¬ speed idling. Throttle position sensor (contact "YU1_") signals the opening angle
