Oil Pressure Switch

A vehicle’s engine requires just the right amount of oil pressure in order to run smoothly. Not properly maintaining the oil in your vehicle can cause damage to the engine and cost you thousands of dollars in repairs. An oil pressure switch helps you to properly maintain your vehicle’s oil pressure which in turn helps you to protect your engine. Most vehicles have a light or gauge connected to the oil pressure switch which alerts you when there is a problem with the oil pressure. The switch triggers the light or the gauge when the oil pressure in the engine drops under a specified level. When the light stays on or blinks repeatedly, you know that it is time to check the oil or take your vehicle to a service shop. Normally refilling the oil will turn off the light.

Some oil pressure lights blink when the engine is first started simply because a cooler engine will not have the specified level of oil pressure. This light should go off once the engine warms up. If it does not you may need to have your oil pressure checked to ensure that you are operating your vehicle at the proper pressure. An oil light signal may also stay on if the switch or gauge is broken or damaged. Replacing a faulty oil pressure switch or light is important to help you to maintain the proper level of oil pressure in the engine. Without the switch and light working properly, there is no way for you to determine whether the engine is receiving the proper pressure of oil to keep it running properly. The switch keeps track of the oil level pressure as oil circulates throughout the engine system.

Newer cars and trucks may have an oil pressure unit that sends a signal to the oil gauge or light as well as the onboard computer. In vehicles with this system, the engine will automatically turn off when the oil pressure drops below a specific level. Checking the oil and both newer and older vehicles is crucial to keep the engine from locking up and causing catastrophic damage to your vehicle. If you feel that your switch or gauge is damaged or broken, having the vehicle inspected and the faulty piece replaced immediately is very important to keep your vehicle’s engine running properly.

You can replace the oil pressure switch yourself if you typically do your own vehicle repairs or take your car or truck to an automotive repair shop. Replacing the switch is not typically expensive, depending on the vehicle’s make and model as well as the shop that you choose for the job. The price of the switch itself will also vary greatly depending on your specific vehicle. Prices may run anywhere from $20 for older vehicles to more than $150 for higher end cars and trucks. You can find a variety of oil pressure switches and gauges at many automotive parts stores and online stores.

The actual act of replacing your oil pressure switch or sensor will also depend on your specific vehicle’s make and model. There may be different steps required for different vehicles. If you are unsure of just how to properly change or replace the switch, it may be better to take your vehicle to a repair shop. You certainly want to ensure that the switch is replaced properly and is in excellent working condition to prevent damage to the internal engine components. If you are planning to replace the switch yourself, be certain that you purchase a manual for your specific vehicle that will help you to find the switch and properly install the replacement part.
