Inspection

PULSE GENERATORS
1. Measure the resistance between terminals 1 and 2 or 3 and 4.
Standard value: 245 ohms at 20° C (68° F)
2. A too small resistance indicates a short circuit and a too large resistance indicates an open circuit.
In either case, replace the pulse generator assembly.

SOLENOID VALVES





1. Measure the resistance between the terminals and valve body of each solenoid valve.
Standard value: at 20° C (68° F)
Pressure control solenoid valve: Approximately 3 ohms
Shift control solenoid valve: Approximately 22 ohms
Torque converter clutch solenoid: Approximately 13 ohms
2. A too small or large resistance indicates a short or open circuit.
In either case, replace the solenoid valve assembly.





3. Connect a 12-V battery between the terminal and body of each solenoid valve and check the operating sound. The valve is okay if an operating sound is heard. No operating sound indicates that the valve is sticking or has accumulated foreign matter. In the case, replace the solenoid valve assembly.
