Do you mean the Vtec solenoid? If you have a CEL (Check Engine Light) illuminated, and you are getting a "P1259" code, it refers to a "Vtec (Variable valve Timing and lift Electronic Control) System malfunction. The Vtec filter screen may be clogged. Disconnect the negative battery terminal. (This will prevent electrical current from going where you don't want it and will reset the CEL. The Vtec solenoid valve is located at the right rear corner of the cylinder head. The Vtec valve is held on with 3- 10mm bolts. Also there is an electical connector that you will want to remove first.

When you take off the solenoid valve, check the valve screen to see if it is clogged. Clean off any crud you find on the filter screens. A good quality spray carburator cleaner works well. If the screen is too yuckked-up to clean, just get a new one. While you are in there, you might want to also check to see that the plunger on the solenoid itself moves freely. If it does'nt, replace it too.

After you put everything back together, do an oil and filter change. Use a high quality oil of the viscosity recommended by the car manufacturer.

God bless and Good luck.

Chrysler 200 2013 62te transmission with 3.6 V6 P0729 code and nothing else. Replaced oil/filter 2X and solenoid pack. All looks good. What is wrong?


code p 0729 refers to gear 6 --incorrect ratio===causes ---fluid level---wiring---TR( transmission ratio) sensor /switch---shift solenoids---transmission mechanical fault
the box is operational so no need for mechanical failure to figure in the diagnosis
if you never use 6th gear, it is possible that the solenoid may be a bit rust inside or a wire has failed from corrosion
at this point I would be checking wiring , connections and pins are not corroded and then consider the TR sensor / switch replacement

How do I change my oil pressure unit


If it is like my 4.6 northstar in 99 deville, it's not easy. From under car look up beside oil filter and you can see to unit. Remove filter for better access, but still not easy.

Tools for oil change


You only need a few. You need a wrench or socket that fits the oil pan drain plug. Car makers have used all sizes of drain plugs, don't know Saturn's, anywhere from 13 millimeter to 19 millimeter size wrench or socket. One of them will fit yours.
So one wrench (when you find the right one) and you will need a drain pan to catch the oil. Next you will need an oil filter wrench or tool. There are several types and sizes-when you buy the new oil filter you can get the filter remover that fits your filter . A parts person should be able to help you select the right one. Also buy a small funnel to pour new oil into the engine .And don't forget to have a few rags handy to clean up spills and wipe off areas. That's about all that is normally required.

Change oil filter


Just the filter: You need a filter wrench that fits your size oil filter. There are 3 or 4 different sizes, so buy the wrench when you buy the new filter to get the right size. Unscrew the old filter. Use the wrench just to loosen it and then you can use your hand to run it off. Have a drain pan to catch the inevitable drips and spills, and to lay the old filter in.` Use a rag and clean the block where the filter's rubber gasket mates to the block. Make sure the old filter's gasket came off with the old filter and is not still on the engine. Where the filter goes on you should see only clean shiny metal.
Before you start the new filter on, it is very important to put clean oil on the rubber gasket on the filter's base. Just dip your finger in oil and run it all around the rubber gasket-if you don't do this it will surely leak there. Now start the filter onto the threaded stud -the mounting stud for the filter-and turn it on down until the rubber gasket is touching the shiny metal base ring on the engine block. Now with only your hands, and not the fil;ter wrench, you need to turn the filter another 3/4 of a turn so it will seal tightly. If you get it half a turn and it gets tight, just squeeze a little harder=get as close to 3/4 of a turn as you can.
You are done. Pat yourself (wipe your hands clean first.). When oil is put in and car is started, check for leaks at the filter.
Good luck.

Where is oil filter on a 2003 alero oldsmobile


I guess Your talking about the 4 cyl 2.2 eng? The filter is in the front center of the Eng, under a Black cover that has a Hex top for a Metric wrench,the size of the wrench? I forgot, hey I'm old!. Clean the area around it with an arisol spray like Brake Clean. Just unscrew it and pull the filter out and replace it with a new one, wet the seal around the top with new oil. done
