The Camshaft position actuator solenoid controls the exhaust camshaft retard position. From 0 to 25 degrees. It is driven by a pulsed electrical signal from the ECM... much like that of a fuel injector. It is located on the front-passenger's side of the motor... on the head. Removal requires the partial removal of the steering pump. It is prone to failure mainly due to debris in the motor oil that flows into it. An oil change and/or removal of the solenoid actuator to clean of the screens of it can sometimes resolve a related DTC.
A person can use a dry, lint-free rag to clean out the solenoid valve. A person can also use oven cleaner and a dry lint-free rag to clean the solenoid valve.Ê
there should be an actuator on the transfer case and on the front diffAnswerthere should be an actuator on the transfer case and on the front diff the encoder motor(solenoid) is on (I think) the passenger side of transfercaseVacuum Switch with vac.lines is on the drivers side kinda of at the top of transfercase, there is a relay behind glovebox(for the push button) and there is a Vacuum Actuator under the battery box with a vacuum line on one end and a cable on the other that runs to the front diff. When you push your button you can actually hear the encoder motor and also the relay behind the glove box. I personally have had problems with the vacuum switch and the vacuum actuator. O.K. not sure if you can clean the encoder motor. They can actually seize up from not being used. I personally use my 4X4 all year (down gravel road, driveway or across yard) to make sure the encoder motors stays functional (these are very expensive)
If the battery tests good and battery cables are clean and tight at both ends and you are jumping the starter solenoid correctly with no results, you probably have a bad starter/solenoid.
Remove the transmission oil pan, remove the valve body, remove the solenoid and check operation of solenoid. Clean if necessary. A simple drain and refill with clean ATF fluid may correct the problem. Make sure you change the filter as well and I would recommend you use a synthetic ATF fluid which will clean the internal components and last longer.
If the transmission solenoid pack is leaking it must be replaced. It can not be repaired. You replace the solenoid by removing the cooler hoses, the input speed sensor and the three bolts that hold the solenoid. remove the solenoid, clean gasket surface and reverse previous steps. Final step is to top off transmission fluid.
You don't clean them - you replace them.
It has been my experience that the battery terminals being dirty will cause intermittent starting problems. Also it could be the starter solenoid brushes not conducting current through to the starter motor. Check the battery terminals first. If they are all white and powdery looking, disconnect them and clean them in a solution of baking soda and water. If they are clean the problem is most likely the starter solenoid. It is best to replace the starter and solenoid as a unit. They are available at most auto parts stores.
Check the latch to insure any adjustments are set correctly, as well as the cable. Check the latch for any bent or broken components. Clean and lubricate it. Check the release cable for kinking or binding, clean and lubricate it (internally). Check the actuator for breakage or binding. Clean and lubricate the actuator. Replace any parts that are damaged or don't operate properly after cleaning and lubrication.
