Cold start injector
(4A-FE (AE92, AE95, AT171 and AT180) and 4A-OE (AE92 and AT160))
Cold start injector. 1 - for deputy ¬ ku ignition 5T1 (AE and AT), 2 - form ¬ sunka cold start, 3 - termovy-klyuchatel nozzles, 4 - Contacts 5 - winding nozzle.
Checking the engine
Check the resistance of the cold start injector.
a) Disconnect the nozzle from a cold start and with the help of th ¬ meter measure the resistance of the coils ¬ nozzle.
Nominal value:
4A-FE. 5.3 Ohm
4A-OE 4.2 Ohm
If the resistance is not in-fall in this range, replace the nozzle.
b) Connect the nozzle.
Removing the cold start injector
1. Disconnect the negative-(-) battery terminals.
2. Disconnect from the nozzle.
3. Remove the tube injector cold start ¬ th:
• Place a substitute vessel or rags under the connection tube
• gradually loosen the two bolts-GOVERNMENTAL bypass, pick up and 4 gaskets.
Check injector cold start ¬ th
Check the quality of fuel injection cold start injector.
Caution: Do not allow the inspection of sparking contacts. a) Set the socket adapter hose to the nozzle and pressure gauge tube, put 2 new gaskets ¬ ki, and connect it by-pass screw.
Connection elements for pro ¬ Verka quality injection cold start injector. 1 - electrical ¬ ka ¬ autonomous electrical connection tropitaniya jets, 2 - gasket, 3 - bypass bolt, 4 - socket adapter to connect the mano ¬ meter, 5 - tube manometer, 6 - ¬ sunka form a cold start.
b) Connect pressure gauge to the fitting adapter.
c) Connect the wires of an autonomous power supply (adapter) to plug the nozzle.
d) Put a container under the nozzle.
e) Connect the wire to the negative-terminal of the battery.
e) Turn the ignition key. Warning: do not run the engine.
g) Short out the conclusions of the "PP" and "+ B" diagnostic connector.
h) Connect the service cord to the battery and check the shape of the fuel jet nozzle
Note: This operation should be is satisfied for the minimum possible time.
2. Check fuel leakage
a) At the end of the last of verification disconnect service pro-water from the battery and make sure that the leakage of fuel through the nozzle jets are not more ¬ Leia one drop per minute.
b) Remove (-) wire from the negative battery terminal Indeed ¬ ¬ ba tarei service and remove the wire and socket adapter with a hose.
