The valve control system ¬ ¬ vleniya rotation frequency of idling
Note:
• engines: 4A-FE (AE92, AE95, AT171. AT180) and 4A-BE (AE92 and AT160), this valve controls the ne-repuskom air besides the throttle valve-term, providing the re-presses the engine warms up, increase solution speed Holo ¬ stack move;
• engines: 4A-FE (AE101, AT190, AE111), 5A-FE (AE110), 7A-FE (AE93, AE102, AE115) and 4A-BE (AE101, AE111) this valve in-grated into the system auto- REFLECTION control the frequency of rotationof the idle, performing greater function.
Checking the engine
1. Check the operation of the valve. (Engines without air flow meter: 4A-0E (AE92, AT160) 4A-FE (AE92, AE95, AT171, AT180))
a) Remove the air cleaner hose.
b) Measure the speed at closing the inlet valve in ¬ to the throttle body.
Scheme of the valve supply additional air ¬ relatively 4A-GE (AE92, AT160) 4A-FE (AE92, AE95, AT171, AT180). 1 - place the valve in the throttle body, 2 - valve assembly, 3 - from the air filter ¬ th, 4 - throttle body, 5 - adjustment screw h ¬ quency of rotation of idling, 6 - the intake manifold, 7 - stop element of the valve, 8 - cooling liquid.
• If the coolant temperature is below 80 ° C at full Stu ¬ screwed adjusting screw speed should be dramatically reduced.
• When the engine is warm and completely screwed regulirovoch Mr. screw speed motion gatelya should drop to values ??of smaller than the minimum sustained speed of a normal idle speed.
Otherwise, replace the valve supply additional air.

b) short-circuit findings Jumper "TE1" and "E1" diagnostic-ray slot.
5 seconds, she again fell to the level of the nominal frequency of rotation of idling. Otherwise, check valve system speed control of the ho-cavity, wiring and electronic control unit ¬ ny. d) Remove the jumper from the diagnostic connector-cal. 2. Check the coil resistance valve.
Note: 5A-PE (AE110), 7A-FE (AE115) 4A-GE (AE101, AE111) ¬ warning Pleasure check valve winding of electrical resistance at different levels of heat, that is when the "cold" and "hot" it states ¬ Research Institute, under this test under the concepts of "cold" and "hot" winding sublattice ¬ zumevaetsya winding temperature valve:
"Cold" -10 ... +50 C
"Hot." 50 ... + 100S
a) Disconnect the valve.
Using an ohmmeter, measure the resistance between terminal + B and other contacts (R5S, P50) connector. Winding resistance: 4A-FE (AE101, AT190), 7A-FE
(AE93, AE102) 19.3 - 22.3 ohms
5A-FE (AE110), 7A-FE (AE115):
"Cold" 17.0 - 24.5 ohms
"Hot." 21.5 -28.5 ohms
4A-GE (AE101, AE111):
"Cold" 17.5 - 28.5 ohms
"Hot." 17,0-24,5 Ohm
If the resistance value of the outputs ¬ DIT the specified limits, replace the valve.
B) (4A-FE (AE111))
Disconnect the valve, including the Chita ignition and measure the voltage-tion between the terminal 2 of connector valve and the "mass".
