Pressure Limit Valve
NOTE:
Terminal numbers for pressure limit valve are a mirror image of connector terminals. See Figure.
- With ignition off, disconnect pressure limit valve connector. Check resistance of isolation valve solenoid winding between terminals No. 2 and 4 of pressure limit valve. Resistance should be 3-6 ohms.
- Check resistance of dump valve solenoid winding between limit valve terminals No. 1 and 4. Resistance should be 1-3 ohms.
- Check resistance of reset switch across terminals No. 3 and 4 of limit valve. Resistance reading should be infinite. If resistance values are not within specification, replace pressure limit valve as an assembly.
