The engineís longevity is largely dependent on how efficient its lubrication system is. This is the reason vehicles are outfitted with an oil pressure switch. Also known as oil pressure sensor or sending unit, this switch ensures that engine oil is of the right pressure to be able to lubricate the engineís moving parts.
If your oil sensor has been with your ride for a while now and youíre starting to notice fluctuations in the engine oil pressure readings, youíd better have it checked as soon as possible. If your troubleshooting efforts suggest that youíre now in need of a replacement switch, donít think twice in getting one. A faulty switch sends out inaccurate readings, making it difficult to gauge if the engine oil level has dropped to critical level.
When looking for a replacement, here are some factors to consider for you to find the switch that will fit your ride well, address your needs, and offer the best possible value for your money.
For the switch to work efficiently, it must be compatible with the engine management system and the entire lubrication system. You see, incompatibility issues can shorten the sensorís service life, or worse, render it useless. So if youíre purchasing online, see to it that the one youíre going to purchase is designed specifically for your ride. Remember that not all oil pressure sensors are the same; they may vary from one vehicle to another, depending on the engine and lubrication systemís setup.
For you to get the oil pressure switch that will fit well in your engine, take note of the stock componentís specifications, including the terminal type, connector, and the thread size. Compare those with the specs of the replacement unit youíre eyeing. If they have the same specs and the sensorís part number matches your stockís part number, then youíve probably found the replacement switch youíre looking for.
While the oil pressure switch rarely gets damaged, it is still important to get one with good warranty coverage. This is because there are defects that only come out after using the part for some time. The productís warranty will assure you that if the switch breaks down within the covered period, you will get a replacement for free.
