Quality of Oil Pressure Switch?

Some time ago, the oil pressure light on my car started flickering. I went to a shop and they told me the oil pressure switch (sending unit) was leaking oil and they changed a new one. A few days later, the light came on again and I went back to the shop. They told me the unit was bad and they changed another one for me without charge. A couple of months later, it started flickering again. This time, the shop told me that the unit was burnt out due to low oil level as the oil level was about 1 quart from the maximum line. Still, they said they changed the unit for me since it鈥檚 still under warranty but they charged me for the labor.





Here is my question. Can oil pressure switch (sending unit) be burnt out that easily just because of low oil level? Where can I find product specifications or other helpful information? Is this normal practice for repair shops?Quality of Oil Pressure Switch?
Other engine parts would fail long before the oil pressure sending unit if you had a low oil failure. One quart low is not enough to cause any trouble at all. Sounds to me like you are either getting inferior parts or the parts are not being installed properly.Quality of Oil Pressure Switch?
its called after market junk stick with original parts that wont happen. A lot of repair shops will not put in fuel pumps unless they are from the dealer 300-550 bucks. the after market ones for 80- 120 will most of the time be back time after time. so they tell ya up front they will not do that twice for free. starters, too a/c pumps too its not uncommon
Your repair shop doesn't know what they're doing.


Oil pressure do not go out all the time,Yes they leak but they're still sensing oil pressure.
try manufacture replacement
I don't see how that many sending units can burn-out when they are designed to operate in a temperature range conducive to that engine block, head and pan. Go to dealer parts dept. for print-out on specs and informative illustrations.
The oil pressure relay does not burn out by low oil. If that were the case, hundreds of thousands of switches would be replaced on a regular basis. Many variables are involved here, and trying to figure out what really is happening is impossible. My inclanation is the shop did not attach the wire to the sender proplerly/tight, or you really have an oil pressure issue. But if the latter is true, then the shop would have jumped at the chance to charge you for a new oil pump, or worse, engine. Have your oil changed, with a new filter, and see if that light comes on again. Some oil pressure sensors, especially on older vehicles, needed to be ';primed'; with a drop of oil before installing.
The light should only come on when your oil level is low. I find it hard to believe that the sending unit (if that is what they changed) could go bad so quickly. First look underneath your car and see if there is oil leaking. Park on a spot where you don't see oil on the ground. Look underneath and see if there is oil leaking. Also check the dipstick for your oil level. If your oil levels stay normal you may not have a problem. The problem is probably the bearings in the crankshaft. You may be able to solve the problem with a heavier weight oil,
