Data are reference values.
NOTE:
Make sure that the pointer swings only momentarily because the output time is so short. If the inspection is done with an oscilloscope, it
should be observed that the power source voltage lasts for 3.5 to 10 ms.

mark (B) facing up. Insert air breather hose into oil catch tank
until it reaches the point where the winding radius stops.
CAUTION:
When installing an air breather hose (air duct side), be careful
not to be crushed or blocked by folding or bending the hose.
REMOVAL AND INSTALLATION (VQ23DE ENGINE MODELS)
During removal and installation of air breather hose (air duct side) be careful of the following.

Align the positions of tightening bolts for drive plate with those of
torque converter, and temporarily tighten bolts. Then, tighten
bolts with the specified torque.
CAUTION:

When turning crankshaft, turn it clockwise as viewed from
front of engine.

When tightening the tighten bolts for the torque converter
after fixing crankshaft pulley bolts, be sure to confirm the
tightening torque of crankshaft pulley mounting bolts.
Refer to EM-53, "
TIMING CHAIN" (QR engine), EM-173, "TIMING CHAIN" (VQ engine).

After converter is installed to drive plate, rotate crankshaft several turns and make sure that tran-
saxle rotates freely without binding.

Install POS sensor. Refer to EM-145, "Removal and Installation" .

After completing installation, check for A/T fluid leakage, A/T fluid level, and positions of A/T. Refer to AT-
14, "Checking A/T Fluid" , AT- 2 1 5 , "Adjustment of A/T Position" , AT- 2 1 5 , "Checking of A/T Position" . : 52 N·m (5.3 kg-m, 38 ft-lb)
