Can Low Oil Cause Camshaft Position Sensor?

One of the crucial parts of your car is the camshaft position indicator. It makes it possible for the car’s engine to understand where the crankshaft drive is positioned. It’s about oil and performance. However, today we came up with the query, “Can Low Oil Cause Camshaft Position Sensor?”

Theoretically, you can burn your piston rings when the timing is wrong. You can start burning oil if your piston rings are damaged. Additionally, you won’t have excellent oil pressure if you burn a lot of oil. A camshaft position sensor might also stop working if it becomes too overheated.

Due to inadequate oil pressure and lubrication, the lifter, camshaft, or timing actuator trouble is probably in the “low oil supply” condition. Anyway, keep reading the article to learn more about camshaft sensors in detail.

What is Camshaft Position Sensor?

how to reset camshaft position sensor

When each valve on a certain cylinder is open, the ECU receives information from the camshaft position sensors, which track the position of the camshaft. The engine control can precisely detect the placement of the crankshaft driven by the camshaft sensor.

Whether the Check Engine Light is on or not, collect the accurate error codes kept in the engine’s control system. This will support the testing of the sensor.

Is the camshaft sensor supposed to have oil on it?

oil on crankshaft position sensor

An engine’s top side has a camshaft sensor that tracks cam rotations to make sure it is in sync with your crankshaft sensor. This part is filled with splashing oil to keep the moving parts properly lubricated. However, this is a common matter that your vehicle’s camshaft sensor contains oil as it’s for proper functionality.

The camshaft sensor is essentially placed through a hole in the head of cylinder and would naturally be coated with oil. Nevertheless, oil contamination caused by a break in your sensor housing can cause sensor failure. Additionally, oil should not be present on the sensor’s outside, non-head portion.

Can a bad camshaft position sensor cause low oil pressure?

Low pressure is typically brought on by a worn engine, crankshaft, camshaft, overheated engine, or rod bearings. The most critical issue for your engine to address is low oil pressure. Oil pressure won’t exist if the automobile won’t start due to a defective cam sensor.

Additionally, low oil pressure and faulty camshaft sensors are not the same problems. You will never have excellent oil pressure if your engine burns oil. If you’re unsure how to fix it, call a professional.

What happens if the camshaft sensor is damaged?

The camshaft sensor is an important factor in your car. A defective camshaft begins to lose its capacity to transfer data faster, which can result in your engine malfunctioning, jerking, poor acceleration, shifting troubles, and poor fuel economy.

Next, inconsistent delivery of fuel weakens the ECM, might cause poor ignition timing, and timing that is off for a few milliseconds will make the car stall, lack power, accelerate poorly, or might stop the car. We hope you understand how crucial that part is!

Can oil leak from camshaft position sensor?

The Check Engine light, or CEL, might come on as a result of oil leaking into the electrical connection of the camshaft sensor. On the right side of the sensor, practically beneath the valve cover, in a place with little turbulence, you will notice the leak. Possibly, you will have to replace the gaskets on the sensors if the (CEL) is off.

What causes the camshaft sensor to go bad?

Generally, the camshaft sensor faces a lot of difficulties due to the heat that the engine generates, just like any other sensor or switch on a car. Your camshaft may break down due to engine dirt and oil, water damage, faulty wiring, or overheating issues.

Sometimes the sensor’s signal from the wires is interrupted by an oil leak brought on by a problematic loose oil cap or a poor head gasket. Fix it immediately or lose the car.

The camshaft is placed at the cylinder head with a durable rubber object. The outside portion of the camshaft sensor would become contaminated with oil if the seal on a worn-out sensor started to leak oil.

How do I test a camshaft sensor?

How do I test a camshaft position sensor?
  • A multimeter can be used to quickly test the sensor. The owner’s manual for your car is also great for determining the power, ground wires, and signals.
  • In the following step, connect your meter leads to the sensor terminal pins while setting the multimeter to DC Volts or Ohms.
  • Between 200 and 900 ohms is the range at which you could get resistance.
  • Two-wire and three-wire camshaft sensors are both testable. Change the multimeter’s default setting from DC volts to AC volts for 2 wires.
  • You will need a company for the task. After that, start the ignition of the vehicle without running the engine.
  • Then, while holding the other probe on the power line, touch the multimeter’s black probe to the ground. If you find any trouble, get a reset.

Can a car run without a camshaft position sensor?

In general, if you forget to install the sensor, the engine won’t start, according to what we found on the internet. However, if the camshaft sensor is absent, your automobile will not turn off. It will work, but not effectively. Your car’s camshaft sensor is basically used to increase power, signal the engine better, and ensure safety.

How to reset the camshaft position sensor

Actually, there are no methods for resetting the camshaft sensor. However, you can check out problems like an illuminated engine light, sluggish acceleration, and stalling. But due to the frequent effects of heat and vibration, camshaft and crankshaft position sensors must be replaced on many cars. 

You can also ensure the sensor’s o-ring hasn’t dropped into its hole by pushing it out. It could be necessary to replace the bolt and install a new sensor.


1. Can the camshaft position sensor leak oil?

It is possible for oil leakage to get into the electrical connection of the camshaft sensor and cause the Check Engine light, or CEL, to turn on.

2. How long does a camshaft sensor last?

The sensor will fail if it is misused or if the engine becomes overheated. The camshaft seal is designed to last for about 80,000 miles. However, in some circumstances, camshaft damage will cause it to wear out before that time. Remember, a car’s camshaft sensor is typically made to survive as long as the vehicle itself.

3. Do you have to disconnect the battery to change the camshaft position sensor?

Disconnecting the negative battery cable is mandatory. When working with sensors or electrical components, you must execute accordingly. The best advice is to take the camshaft sensor out from underneath your car, but you can also do it from the top by taking off the filtration housing.

4. What do you do after replacing camshaft sensor?

Once the sensor has been replaced, make sure to use a diagnostic scanner to clear any error codes that were recorded in the engine controller following the failure. It might be necessary to re-learn and reprogram the sensor, or if the reading is optimal, skip programming the sensor.

Final Section

So, we have described how valuable the camshaft sensor is! All the issues concerning  “Can Low Oil Cause Camshaft Position Sensor,” have been discussed.

We mentioned how it affects the car, how it performs, and what the disadvantages are of not having a camshaft sensor. Now, you can test the sensor and determine if there is any low oil issue linked with the camshaft sensor to fix the vehicle for better performance.
