A/T Clutch Pressure Control Solenoid Valve
Test
1. Disconnect the transmission sub-harness connector
(HP).
2. Measure the resistance between the No. 8 and No. 9
terminals of the transmission sub-harness connector.
STANDARD: 4.0 - 6.0 (at 70°F, 20°C)
3. If the resistance is out of specification, remove the
shift cable cover, and disconnect the shift solenoid
valve/A/T clutch pressure control solenoid valve
harness connector.

4. Measure the resistance between the No. 3 and No. 4
terminals of the shift solenoid valve/A/T clutch pres-
sure control solenoid valve harness connector.

• If the resistance is within specification, replace
the transmission sub-harness.
• If the resistance is out of specification, replace
the A/T clutch pressure control solenoid valve.
5. If the resistance is within the standard, connect the
No. 4 terminal of the shift solenoid valve/A/T clutch
pressure control solenoid harness connector to the
battery positive terminal, and connect the No. 3 ter-
minal to the battery negative terminal. A clicking
sound should be heard. If no clicking sound is heard,
replace the A/T clutch pressure control solenoid
valve.

8. Check for continuity between the terminal in each switch position according to the table below.
• Move the shift lever back and forth without pushing the shift lever at each switch position, and check for continuity
within the range of its free play.
• If there is no continuity within the range of free play, adjust the transmission range switch.
