About Camshaft Sensor

About Camshaft Sensor

The camshaft sensor is a part of the engine that monitors the movement of the camshaft and provides data to the vehicle’s ECM (Engine control module). As you probably know, the journey to bring the gas and fuel mixture must take place for the engine to work well.

It happens when the valve opens and closes at the right time. And to do that, the camshaft is responsible for opening and closing the valve at the right time. When everything goes according to a particular cycle, your car will move faster and further. The combustion stroke will be misaligned if the crankshaft and camshaft are not aligned.

Tristan’s kinetic energy then contacts the valves and damages them. The most significant loss that can happen is your car’s engine failure. Therefore, the camshaft plays a substantial role in the vehicle’s equipment. However, not too many people understand its importance leading to bad situations when the camshaft malfunctions.

Is It Safe To Drive With A Bad Camshaft Sensor?

It is undoubtedly a question you will ask when you encounter a bad camshaft sensor. As we said above, the camshaft position sensor plays a significant role in the vehicle’s equipment. If the camshaft sensor is wrong, you can still drive usually. But to answer whether it is possible to drive safely with a lousy camshaft sensor, the answer is no.

The best way to see if it’s safe is to check the acceleration while running.

When the driver does not see the phenomenon of jerking or stalling when accelerating, you will drive safely. When the check engine light flashing then stops 504, it is a sign of impending danger.

Many vehicles may still be safe to drive while others are difficult to navigate. Although the level of safety depends on each vehicle model, when driving with a poor camshaft sensor, your car will operate slowly, with low performance. Therefore, with poor sensors, we need to go to repair immediately.

Why Is The Sensor Faulty?

To fix and repair the sensor, you first need to know the causes of the faulty camshaft sensor. Many factors affect the sensor, most notably water and fuel oil stuck in the vehicle’s equipment.

Besides, during long-term use, the sensor has been corroded. In addition, it also failed from previous accidents. Oil leak due to open cover is an indirect cause of faulty camshaft position sensor. This problem occurs in many engines, and it is pretty ordinary compared to today.

Common Sign For A Bad Camshaft

  • Engines often run at low productivity or stop working. The reason is that when the sensor is wrong, it doesn’t tell you what position the camshaft is in, causing the injectors to enter the fuel at the wrong time. If you are stuck in traffic, traffic jams, this causes tremendous obstacles for vehicle drivers.
  • While running, the engine jerked or suddenly spiked. The signal comes from the powertrain control module not receiving any information transmitted by the camshaft.
  • A poorly functioning sensor will lock your vehicle’s transmission for vehicles with a message. It makes it impossible for you to move forward or reverse gears. At that point, you can just shut down and restart. It is not a problem if you run long distances, but the bridge is dangerous and causes an accident if you are going uphill.
  • When traveling on the road, if you realize that the fuel consumption is more significant than usual, but the performance is still stable, it may also be due to a problem with the sensor.
  • The engine light on or flashing is also one of the symptoms. You need to use an OBD2 scanner to find out the real cause of the light on the dashboard. In the case of lights, you should find a repair specialist to have the best solution.

Frequently Asked Questions(FAQ’s)

How to clean the camshaft sensor?

To avoid sensor damage, users must regularly clean the sensor with the following steps

  • Step 1 Disconnect the front engine audio
  • Step 2 Observe the front and rear of the vehicle, find the position of the camshaft
  • Step 3 Remove the sources associated with the sensor wire
  • Step 4 Tighten the bolt to remove the sensor from the device
  • Step 5 Apply oil to the new sensor and dry it
  • Step 6 Install the new sensor in its original position
  • Step 7 Reconnect CMP and test drive

How much does the repair cost?

Unlike the rear main seal replacement cost 289, fortunately, sensor repair is not expensive. If you do not have experience, you should go to a mechanic and ask them to fix it. Depending on the structure of each vehicle, repair costs vary.

Usually, it will range from $150 to $250. Seasoned people will choose to replace the sensor themselves at home for only $ 20 to $ 30. So, you don’t need to worry about this.
