What to Do After Replacing Camshaft Sensor (Explained)

What to Do After Replacing Camshaft Sensor

What to do after replacing a camshaft sensor is to use a diagnostic scanner to clear the error code or reprogram your engine to erase the check engine light on the speedometer. 

The fastest way to render your engine powerless is to have your camshaft go haywire. A camshaft sensor is that electrical device used to monitor the positioning or the rotational speed of a camshaft both in a petrol and diesel engine.

When a camshaft sensor fails, it is more like a man with a bad day; everything he does simply goes wrong. Such applies to a camshaft sensor whenever it goes wrong; it sends unreliable info to the engine like mismatched fuel delivery, wrong ignition timing, etc.

A minor error can take your vehicle on a journey of poor delivery. Your engine can shut down. There are various reasons a camshaft position can fail. It may result from previous accidents, wear and tear, etc.

Even with that, a camshaft doesn’t give up working all at once; it gives red signals to the car owner to have it fixed as soon as possible.

When to Replace Camshaft Sensor?

It sometimes gets confusing to understand which and which is the problem, the camshaft sensor or the crankshaft position sensor.

Because they work in hand to make a vehicle function well and the similarities to their names, it feels cranky and tricky to truly understand if you are a newbie who is told everything about a car.

A camshaft is always attached to the crankshaft with a timing belt. A failure in the camshaft can cause a bit of serious is malfunctioning to a car.

You can call it is the “Cancer attack”. It comes with symptoms and strikes aggressively when not corrected fast at its early stage.

You replace your camshaft sensor when you have read red signs/ symptoms of damages from your vehicle. A few symptoms you should note include:

  • Reduction in engine power
  • Stalled engine
  • Vehicle refusing to start
  • Rough idle
  • Visible of an engine light

However, before replacing your camshaft sensor, there are certain things you have to know such as knowing how to identify unknown camshaft. You need to know how to identify the type of camshaft your car uses to be able to get the right one for your car.

What to Do After Replacing Camshaft Sensor?

Not knowing what to do after replacing a camshaft sensor is still a “No movement” to the engine. You still get stressed, frustrated, and almost hit your hands on the car to push out your anger because you don’t know what next to do after having the camshaft replaced.

After replacing your camshaft, your engine controller probably still has error codes labeled all over it. To have this clear off, you need to use a diagnostic scanner to ensure the errors are canceled after failing. In a simple term, you need to “reprogram” to bring your vehicle back into action.

Also, you have to make sure that the connection and mounting bolt are wired appropriately otherwise, you are likely going to continue seeing the check engine light on even after clearing the error with a code reader. It will clear, but after driving for one or two miles, it will come back on to show that something is still not with the work you did.

Can You Reset Camshaft Position Sensor?

Yes, you can reset a camshaft position sensor with car equipment such as a voltmeter and ohmmeter.

Resetting a camshaft position sensor can be done if precautions are followed duly even as a newbie with little or no knowledge about vehicles.

  • The inductive performance of the sensor should be checked with a voltmeter and ohmmeter
  • Turn off the car ignition to take a few measurements
  • Verify the resistance, ensuring it is between 200-900Ω
  • Verify the measured resistance with the car’s standard data
  • Have the terminals of the voltmeter connected with the sensors
  • Startup the engine again, leaving it running without driving it
  • Your RMS value should exceed 0.75V

Advantages of a Good Camshaft Sensor

There are various reasons you need a good camshaft sensor as a vehicle owner. Aside from breaking free from stress, there are other interesting factors that can’t be neglected. They include:

1. Considerable Fuel Consumption

Aside from a peaceful ride, it is the joy of every vehicle owner to spend the desired amount of money on fueling and not be in a position where they are forced to spend extra because of the overconsumption of fuel by the engine.

Overconsumption of fuel isn’t so much of a pleasant experience, particularly if the driver isn’t so much buoyant in resources; they restrict their movements just to maintain fueling.

Having a good camshaft can save you from the stress of spending excessively on fueling.

2. A Good Driving Experience

A bad engine will cause a bad driving experience. Nothing is so shaming, like having your car break down with a client in it. It can be painful when your engine doesn’t function normally.

Every driver doesn’t want to be pained for handling engines the wrong way. More reason it is recorded that drivers give more attention to their car engines compared to other components of the car.

With a good camshaft, your engine efficiency is high. A splendid car is a good car, not because of the beauty alone, but because you can drive it in peace.

3. Swift Use of the Gear

Another interesting factor every fast driver will love is to harness the power of their gears to the best of their ability.

With a camshaft problem, it becomes stiff to adjust gears to taste. It wouldn’t be a pleasant experience to be on a highway to slow down or push in a little nitro and you have your gear seizing.

4. Doesn’t Flash the Danger Engine Light

Having a peaceful ride is another way to enjoy life. Drivers jump into a state of panic immediately they see flashes signaling danger from the engine part of the car.

Even if the driver is of high hopes and resilient, at the sight of the sparks of flashes signaling the engine is cursed with a problem, any driver grows into a state of panic, and an urge to check what is wrong arises.

A good camshaft cannot be deeply emphasized other than the peace it delivers to the car and the car owner likewise.


It is explosively great to know what to do after encountering a problem with your car. Fixing up your camshaft can be easy, resetting isn’t hard too. Therefore, know what to do after replacing the camshaft sensor in your car.

A sprinkle of focus and knowledge with a ready-to-get-it-done mentality is good enough to reset and do everything that involves your camshaft sensor.

It can frustrate and be petty confusing if every detail isn’t properly followed, but with enough understanding, you can get it done all by yourself.
