5. Start engine and measure line pressure at idle and stall speed.
CAUTION:
 Keep the brake pedal pressed all the way down during
measurement.
 When measuring the line pressure at the stall speed, refer
to "STALL TEST".

JUDGEMENT OF LINE PRESSURE TEST
SAT493G
Engine speedLine pressure [kPa (kg/cm
2, psi)]
D, 2nd and 1st positions R position
Idle speed 500 (5.1, 73) 778 (7.9, 113)
Stall speed 1,173 (12.0, 170) 1,825 (18.6, 265)
Judgement Suspected parts
At idleLine pressure is low in all positions.  Oil pump wear
 Control piston damage
 Pressure regulator valve or plug sticking
 Spring for pressure regulator valve damaged
 Fluid pressure leakage between oil strainer and pressure regulator valve
 Clogged strainer
Line pressure is low in particular posi-
tion. Fluid pressure leakage between manual valve and particular clutch
 For example, line pressure is:
− Low in “R” and “1” positions, but
− Normal in “D”, and “2” positions.
Therefore, fluid leakage exists at or around low and reverse brake circuit.
Refer to TM-14, "
Shift Mechanism".
Line pressure is high.  Accelerator pedal position signal malfunction
 A/T fluid temperature sensor damaged
 Line pressure solenoid valve sticking
 Short circuit of line pressure solenoid valve circuit
 Pressure modifier valve sticking
 Pressure regulator valve or plug sticking
 Open in dropping resistor circuit
At stall
speedLine pressure is low.  Accelerator pedal position signal malfunction
 Line pressure solenoid valve sticking
 Short circuit of line pressure solenoid valve circuit
 Pressure regulator valve or plug sticking
 Pressure modifier valve sticking
 Pilot valve sticking
