A340E (2JZ—GTE) AUTOMATIC TRANSMISSION – TROUBLESHOOTING

INSPECTION PROCEDURE

1  Check No.5 solenoid valve.

Check solenoid resistance

P  1.  Jack up the vehicle.
   2.  Remove the oil pan.

C  1.  Disconnect the solenoid connector.
   2.  Measure resistance between terminals 1 and 2
       of solenoid connector.

OK  Resistance: 3.6 — 4.0 .

Check solenoid operation

C  Connect positive × lead with an 8 — 10 W bulb to
   terminal 1 of solenoid connector and negative ⊕
   lead to terminal 2, then check the movement of the
   valve.

OK
When battery positive voltage is applied.  |  Valve moves in ➡ direction in illustration at left.
When battery positive voltage is cut off.  |  Valve moves in ⬅ direction in illustration at left.

<Reference>
Check solenoid operation

C  1.  Prepare a variable power supply.
   2.  Connect positive × lead of the variable power
       supply to terminal 1 of solenoid connector and
       negative ⊕ lead to terminal 2.
   3.  Check the movement of the valve when the
       voltage is gradually increased. (A current
       greater than 1A should not be supplied.)

OK  As the voltage is increased, the valve should move
    slowly in the ➡ direction.

C  4.  Check the movement of the valve when the volt–
       age is cut off.

OK  The valve should return in the ⬅ direction.
