The Top 3 Warning Signs Your Oil Pressure Sensor Is Broken

Oil pressure drives engines. This is one of the main components that make sure a vehicle is running smoothly. Otherwise, damage and malfunction could lead to bad consequences.

The oil pressure sensor monitors this internal pressure and provides a signal to the oil pressure gauge on the dashboard, alerting you to any potential problems. The driver can pull over and investigate the problem before it becomes necessary to make costly repairs. 

To avoid engine damage, all metal surfaces that endure rapid motion must be regularly lubricated. It is critical to have a firm understanding of the repercussions of a faulty oil pressure sensor on your engine.

Read on to discover the top three warning signs your oil pressure sensor is broken.

Oil Pressure Sensor Warning #1: The Warning Light

Here, you may notice that the oil pressure indicator or warning light is flashing. If the warning light is illuminated, yet the dipstick indicates that there is sufficient oil in the engine, the problem is most likely caused by a faulty sensor. If the engine is making loud grinding or ticking sounds despite having enough oil, the oil pump could be faulty. 

Under no circumstances should the engine be started until it has been repaired. If the oil level is low, it could be a sign that a hose or gasket is leaking, or it could mean that the combustion chamber is consuming too much oil. If you continue to drive until the problem is resolved, you risk inflicting substantial engine damage.

A helpful reminder is to note that regardless if your sensor is damaged or not, you should inspect it every time this warning light illuminates. 

Oil Pressure Sensor Warning #2: The Oil Light

The majority of the time, oil pressure problems are not intermittent. It is quite unlikely that it will change. As a result, a blinking oil light shows that the sensor is malfunctioning. If the car is older and does not have a low oil pressure warning light, the check engine light may illuminate. 

There are several types of service engine soon lights, and not all of them are related to oil pressure. Before proceeding, check the oil level and listen carefully for any strange sounds.

Oil Pressure Sensor Warning #3: The Oil Pressure Gauge

A malfunctioning sensor may cause the gauge reading to remain excessively high or zero. Either a short circuit in the sensor's circuitry, resulting in an excessively high reading, or a breakdown in the channel delivering the signal, resulting in a zero reading. Damage to the wiring harness, rusted plugs, or broken connections are all possible causes. Check the engine and the dipstick again to rule out the possibility of low oil pressure. A risky condition for your car is when the oil is overfilled, which can cause foaming and low pressure.


Having a car and driving it is not only a convenience or a privilege, but it is also a responsibility. One of the responsibilities that entail being a good driver is to make sure your car is in working order.

Damaged oil pressure sensors are an annoyance as well as a safety risk. It will quickly become tiresome to have to pull over and investigate every time one comes. If there is a problem, you run the risk of becoming complacent and presuming that the sensor is defective. Inefficient sensors do not identify engine defects until they generate annoying and sometimes costly noises. 

If the sensor has been compromised, replace it immediately. It will avoid annoyances as well as costly and time-consuming car damage.
