    Anyone ever tackle changing one of these.. I have done about all the research I can online to figure out how to change it.. Just wondering if it’s worth tackling on your own or if it’s worth bringing to the shop to get it done.. Even for a girl, I’m pretty handy, do my own brakes, rotors, calipers, oil changes, plugs, thermostats etc… Just wondering if I’m getting in over my head on this one… It’s an 05 Chev malibu that I will be replacing the sending unit on… Any thoughts??

    are you sure it is the switch and not a gauge going bad!

    You are sure you have oil pressure? if you have a mechanical gauge you can screw it in where you take out the old switch to check and see if you have good oil pressure! If you do then buy the switch! if it still reads low its your oil pressure gauge going bad..

    it’s usually not bad to replace but most likely will need a special socket to do the job…..

    Yep I’m sure.. Check engine light came on Friday, brought it to my mechanic and had him scan it (as I was driving my car to the cities saturday for a funeral and didn’t need problems getting down there)… Got a code for the oil pressure sending unit, my thermostat (which is just getting weak, still have good heat.. will be changing same time as the sending unit), and the last code was for the shift lever, which I knew was already bad… (The great makers of GM products definantly screwed up the design on my shift lever. There is a wire that runs down for the “Low” gear where you can switch between 1-4th gears. That wire gets pinched when you shift between park, drive, reverse etc over time.. I’ve already replaced the shift lever once, then just fixed the wire that was bad on the old one so I have a spare..) I only drive this car in the winter, and drive my VW Jetta TDI in the summer, if it weren’t for it being my winter car, it’d be sent down the road.. Have had way too many problems with it from the time I bought it new.. Think it was made on a monday or a friday…

    As handy as you are I’m surprised you don’t have a code reader. They are relatively cheap now days at $75 for simple ones.

    Might just have to pick one up, cause between my cars at my house and my parents abundance of vehicles at theirs it would pay for itself… $35 to scan it at my mechanic…

    If I had to buy another one,I would get one that reads live data.They don’t cost much more than one that just reads/erases codes.
