Suppose you drive along and there suddenly your car will stall maybe when you come to a halt at traffic lights or roundabout. In that case, a cam sensor could be a great help to change the engine control for ultimate fuel power. If any sensors fail, hence the engine becomes rough to run or even causes problems to start the vehicle, then, you need to replace the camshaft position sensor.

Now the question is, what to do after replacing camshaft sensor? When you replace the camshaft sensor, you need to take a diagnostic scanner to cancel the error code after failing. Remember that the code is stored in the engine controller. Also the camshaft position scanner can’t repair or reuse if it fails. 

That’s a glimpse of your initiative. But, you need to know a lot. In the following discussion, we will notify you of those. Hopefully, you can get the camshaft position sensor-related problem at the right time. So, let’s get started.

How to Check a Cam Sensor?

How to Check a Cam Sensor
  • Typically, you will find the crankshaft sensor on the bottom of your engine behind the harmonic balancer. In some cars, the crankshaft sensor is located on the back of the engine on the bell housing.
  • There are a few different types of crankshaft or camshaft sensors available. But, in our discussion, we only focus on one type, camshaft sensors.
  • To discuss, we choose the magnetic type sensor. This type of sensor comes with two wires and produces their voltage. 
  • While testing, you don’t need to remove the sensor from the car; instead, you can do it from your car. 
  • First, you need to look at the plastic housing of your sensor to see whether there are any major cracks or damage or if it’s bent out of shape. Those signs will indicate you have a bad sensor.
  • Now, get your multimeter to do a resistance test. Then, you need to put the multimeter on the ohms settings. As the resistance, we get about 2000 to 2500 ohms of resistance in our camshaft position sensor. 
  • You can choose 20,000 ohms on the scale of this multimeter, and then we will take our measurement. Now, we get 2.01 thousand ohms of resistance or 2010 ohms.
  • Also, you need to examine the condition of the connector for your sensor. 

What to Do After Replacing Camshaft Sensor?

After replacing the camshaft sensor, you need to choose one from those two different things. One is either you can reprogram, or you don’t.

What you do after Re-Program:

The suitable time of firing the injection and ignition can be determined using ECM with your old crankshaft sensor and new camshaft sensor. Also, ECM will notify you of the time between the module and sensor the signal pulses to and from. 

You can use that time against your present data table to know the suitable time difference between the pulse separations. 

In the optimal reading, you don’t need to program the sensor. Sometimes the sensor may show error code after replacing. 

Now, you need to examine all the connector issues and then write and repair or cancel them. After that, you still get codes. Then, don’t worry, your camshaft sensor is fine and nothing wrong occurs herein. 

When to Re-Program:

The sensor demands relearning some things because of the installment’s variation. But, that thing depends on the manufacturer and the professional’s service. The previous data table’s information will be reset because of that relearn. 

Then, the meaning of the signal’s new sensor will be learned by ECM. If this is the case, the sensor needs to be reprogrammed. 

Otherwise, you may see trouble codes, and the engine performance becomes poor, eventually because of low power conditions. 

That’s why the local car dealership is considered the ideal place to reprogram and re-learn the sensor.

What to do after replacing crankshaft sensor

Some owners complained that they got error codes after replacing the crankshaft sensor. 

So, what do you do then? If you face that issue, remember that the problem isn’t associated with the wiring between the ECU and the sensor. You can check the rubber ‘O’ ring that came out along with the old sensor. 

Most importantly, don’t forget to remember that the air gap between the replacement sensor and the tone wheel will increase if the ring lies in the sensor cavity. That is the cause of showing the error code. Also, cleaning the power steering reservoir after replacing your crankshaft sensor is always a good idea!

How long does it take to replace a camshaft sensor?

Interestingly, removing and replacing the camshaft sensor from your vehicle is easy. Plus, replacing a camshaft sensor doesn’t take much time. Usually, the replacement may take about 5-10 minutes. 

Let’s see some important points while replacing.

  • Whenever you work with electrical components or sensors, you have to disconnect the positive battery cable.
  • After removing, diagnose the pigtail to find any damage or dirt. Remember that corrosion and oil could hamper the signal from the sensor to the engine control module. Also, you need to carefully examine the sensor to ensure it does not leak another engine component. If you see any damage, you need to repair the leak to prevent the new sensor from being damaged. Moreover, examine to ensure the o-ring from the sensor hasn’t fallen into its hole.
  • After replacing, push the new sensor into place, replace the bolt and electrical connector, and tighten the bolt based on the manufacturer’s specifications. But be careful that the bolt isn’t overtighten because it may damage the mounting ear of the new sensor.
  • Finally, you need to check the engine light is still on after replacing the camshaft position sensor.

How much does it cost to replace the camshaft sensor?

To me, the CMP (camshaft position) sensor replacement cost depends on the following variables:

  • Pricing charts from the different automotive experts
  • Cost of parts associated with the vehicle and
  • The labor cost in your area

Generally, CMP sensor cost to replace typically lies between $95 to $200. On that, the cost of the parts is higher, about $25 to $100. Then, if you take professional help, the labor cost will be $70 to $100. 

However, the luxury vehicle may cost you more than other traditional cars. 

Camshaft Position Sensor Replacement Cost (Average):

Frequently asked questions (FAQs): Replacing camshaft sensor

Is the camshaft and crankshaft sensor the same?

No, the crankshaft helps to convert power from a piston to rotational energy. On the other hand, the camshaft is used as a control device in diesel engines and used to pump fuel into the cylinders. 

Moreover, it opens and closes the valves to match the four-stroke cycle of the Pistons valve operation, piston motion, fuel delivery, and ignition.

Why does my camshaft position sensor keep going bad?

You will find a couple of reasons why the camshaft position sensor keeps going bad. One of the most common reasons are water damage, oil embedded in the engine, and wear-and-tear.

Also, corrosion leads the camshaft position sensor to fail, and it becomes a common reason behind failure. 

Another reason is the accident which also makes the camshaft sensor position bad. When you diagnose the failure, you have to replace that camshaft position sensor and associated items. 

Not all the time, your camshaft becomes bad. But, sometimes, the oil leak caused by a defective, bad head gasket or loose oil cap may hamper the sensor’s signal. 

Notably, the failure of the camshaft scanner sensor isn’t uncommon, and it may have been linked to other components of the engine.

Do you have to replace both camshaft sensors?

Experts recommend replacing both camshafts at the same time. The replacement process of the camshaft and the crankshaft is the same. 

But, you may face difficulty while detecting the location of the crankshaft. Another point is you should diagnose before replacing. While checking, you will find the camshaft code 1200, which could be a mechanical problem.

Why do you get code after replacing the crankshaft position scanner?

Replaced crankshaft position sensor but still get code? If so, then you don’t need to replace it. When ECM doesn’t recognize the signal, the signal is erratic, or the signal isn’t there. If you get an error code, you can check the rubber ‘O’ ring. 

What to do if the replaced camshaft position sensor light still on?

You can check the following instructions if you find that the replaced camshaft position sensor light is still on.
01. Check the connectors and wiring very carefully.
02. You can also check the crankshaft position sensor
03. Finally, don’t forget to inspect cam position gear

I replaced the crankshaft position sensor but still got code; now, what should I do?

First of all, you can put a scanner in your car to confirm the problem. Most probably, if you have a faulty crankshaft position sensor, then you may get code. 
In that case, you can buy a crankshaft position sensor and install it in your car to solve the issue.

Also, you can experience the same problem due to the following issues:
01. Spark plug problem.
02. Problem with wiring for the CPS circuit and
03. Engine problems

If you still face a problem to fix the case, you can rely on a professional mechanic.

Final Thought

After bringing your vehicle to the servicing center, the mechanic doesn’t check your camshaft position scanner. You need to tell them to check carefully. 

Hopefully, our discussion will teach you when you tell them to check. Plus isn’t overtightened; you become aware when the camshaft position scanner demands changing and what to do after replacing the camshaft sensor.
