[Comment] of the throttle If the TPS output becomes 4.6 or more at idle, TPS output is excessive, and of connector
trouble code No. 11 is output. If the TPS output be comes 0.2 or less at times other than l of idling, TPS output is insufficient and diagnostic t rouble code No. 12 is output. If the TPS output
and the target value inside the TCM do not match ev en after compensation is carried out while
the engine is idling, the TPS sensor is defective and diagnostic trouble code No. 13 is output.
If the TPS voltage becomes 0.2 or less or 1.2 or more while the engine is idling, the
TPS adjustment is defective and diagnostic trouble code No. 14 is output.

Code No. 15, 16 Oil temperature sensor system
[Comment] If the oil temperature sensor output is 4.4 or higher (oil temperature does not increase) evenafter driving for 10 minutes or more, there is an o pen circuit in the oil temperature sensor
and diagnostic trouble code No. 15 is output.
When the oil temperature sensor output is 0.2 or less (for 1 second or more), it is judgedthat there is a short-circuit in the oil temperatur e sensor and diagnostic trouble code No. 16is output.

1. Disconnect the servo switch
2. Remove the servo
3. Check that there is continuity ‘-‘between servo
switch side connector terminal 1 and the inside
the servo switch.
4.If there is no continuity, replace the servo switch.
5.If continuity exists, push in on servo switch. Check that
no continuity exists between terminal and the metal
inside the servo switch.
6. If continuity exists, replace the
servo switch.
OIL TEMPERATURE SENSOR CHECK
1. Disconnect the oil temperature sensor connector.
2.Measure the resistance between the oil temperature sen-
sor side connector terminals 1 and 2, and check that
the values are as shown in the table below.
Standard values:
Oil temperature Resistance value
(32)
100 (212)
3. If the values are outside the standard values, r eplace
the oil temperature sensor.
VEHICLE SPEED SENSOR CHECK
1.Remove the vehicle speed sensor and connect a
resistance as shown in the illustration at left.
2. Turn the shaft of the vehicle speed sensor and c heck
that there is voltage between terminals 3. (1 turn

2. Remove the oil pan.
3. Remove the oil filter.
4. Remove the oil temperature sensor.
5.Press the solenoid valve harness grommet and connec tor

REDUCING PRESSURE ADJUSTMENT 23100180033
WHEN SCAN TOOL IS NOT USED 1. Remove parts up to the oil filter in the same wa y as
for adjustment of the line pressure. The valve body need
not be removed.
2.Tune the adjustment screw of the lower valve body a nd
adjust so that the reducing pressure is the standard value.
When the adjustment screw is turned clockwise, the reduc-
ing pressure decreases; when it is turned counterclock-
wise, it increases.
NOTE
When adjusting the reducing pressure, aim for the c enter
value
(60 psi)] of the standard value allowance.
Standard value: 415-435 psi)
Oil pressure change for each turn of adjustment,
screw: 45
(6.5 psi)
3. Install the oil filter and oil
in the same way as for
adjustment of the line pressure.
4. Perform the oil pressure test. Readjust if neces sary.
WHEN SCAN TOOL IS USED 1. Use the scan tool to force-actuate the pressure control
solenoid valve to 50
duty, and measure the
brake apply pressure at that time. If the brake
apply pressure is not within the standard value, ad just
using the reducing pressure adjustment screw.
Standard value:
(36-44 psi)
Oil pressure change for each turn of adjustment
screw: 22
(3.2 psi)
2. Check to be sure, after completing this adjustme nt, that
the reducing pressure is within the range of
(51-68 psi).
Caution
The adjustment should be made at an oil temperature

If the adjustment is made at an oil temperature tha t
is too high, the line pressure will decrease during
idling, with the result that a correct adjustment c annot
be made.
