Solenoids valves are used at the intake and purge. These are different valves and should not be interchanged.

If the Intake Solenoid fails to function, this can be replaced as a separate item. This solenoid (identified by the red coil wire) is NOT a replacement for the Purge solenoid. While it possible that a disassembly will be able to clear a clog, generally the problem is a worn part. .When ordering Cat #28413 intake solenoid (red wire), the coil comes terminated and ready to use.
