COMPONENT INSPECTION

Line pressure solenoid valve

Resistance check
- Check resistance between two terminals.

Operation check
- Check solenoid valve by listening for its operating sound while applying battery voltage to the terminal and ground.

Dropping resistor
- Check resistance between two terminals.

Resistance: 11.2 - 12.8 Ohms
