A crucial component of your system’s engine is the position of the crankshaft sensor. It aids in letting the PCM know how the crankshaft is doing. The crankshaft position sensor, like other auto parts, is susceptible to damage from a variety of sources, such as poor wiring, an overheated engine, and other issues.
Your car will display some symptoms as soon as the sensor is damaged. Driving is extremely challenging and occasionally impossible due to these symptoms. For instance, if you are on a highway and your car breaks down due to a crankshaft position sensor failure, getting out of the situation can be very difficult.
There are workarounds that can be used in the meantime while the sensor is being replaced as the long-term fix.
- Try to start the Vehicle by doing things like checking the fuel level, checking the crankshaft sensor plug, and restarting the engine.
- Because it is an electronic sensor, it cannot be repaired if it is damaged or malfunctions within.
- Because there is no way to fix it. Therefore, replacing the crankshaft position sensor is your only remaining potential choice.
Crankshaft Position Sensor Problem Symptoms.
When there is an issue with the crankshaft position sensor, some symptoms start to emerge. They consist of;.
|A sudden stop of the vehicle.|
|The car was jerking.|
|An increase in fuel usage.|
|On the dashboard, a pop-up.|
There are a few things you can do to temporarily repair the issue if any of the aforementioned occur while you are driving. Due of the inability to repair the sensor, these techniques can only be used to get you to your goal.
What is A temporary fix for Crankshaft Position Sensor?
By addressing the specific symptom or sign your car is currently exhibiting, you can momentarily fix the crankshaft position sensor issue. The crankshaft position sensor problems with your car can be temporarily fixed in the ways listed below.
Start the engine again.
A malfunctioning crankshaft position sensor may be to blame if your engine starts jerking or trembling all of a sudden when you’re driving or the engine is just sitting idle.
Turning off the engine is one solution to this issue. Before starting the engine again, you should let it cool down for a while.
You can lessen the shock that is produced in the engine system by doing this. The check engine light-accompanied shaking and jerking issue is typically brought on by a communication breakdown or miscommunication between the crankshaft and the powertrain control module (PCM).
Removing the Crankshaft Position Sensor connection.
Disconnecting the sensor is another easy fix for any CKP sensor problems your car may experience. When you are stranded and your engine won’t start, you can do the disconnection.
A CPK sensor and PCM issue could be the cause of your engine not starting. You must find the CPK sensor in order to detach it. They often stand close to the crankshaft. If you’re having trouble finding it, you can utilize the owner’s manual. The connectors for the CKP sensors can be taken out when the sensors have been found.
You can start the car once the connection has been cut. After disconnecting the crankshaft position sensor, if the engine still won’t start, you should take it to a qualified mechanic. Another issue could be the root of the slow start.
Refuel the engine.
Try to refuel your tank if your engine fails unexpectedly while you are driving. Failure of the crankshaft sensor may result in the PCM providing the engine system with insufficient gasoline.
More gasoline will be able to reach the engine’s combustion system, which could temporarily solve the issue.
How to Repair a Broken Crankshaft Position Sensor?
You will need to replace the crankshaft sensor if it sustains damage because there is no way to repair it. If you want to obtain the maximum performance possible out of your engine system, the crankshaft sensor must operate at full capacity.
We do not advise attempting to fix a crankshaft position sensor that is malfunctioning. At a reputable technician, replacements are typically inexpensive. Budget between $175 and $230 per month. Labor charges are not included in the price and will be an additional $100. If the correct procedures are followed, replacing the CKP sensor is easy.
It is better to replace the CKP sensor because doing so could prevent your engine from failing completely. All crankshaft monitoring is disrupted when the sensor or its wiring breaks. The crankshaft will be unable to be controlled and monitored by the PCM, stalling and shaking violently.
Eventually, if the sensors are not changed right away, it will result in a more serious engine issue that might result in engine failure.
Drawbacks of Crankshaft Position Sensor Repair.
|The drawback of fixing a crankshaft position sensor is that it cannot be fixed permanently; you must buy a new crankshaft position sensor to replace the damaged one.|
|You will still need to reset the newly fitted crankshaft position sensor after the replacement is complete.|
|It is only possible to fix a crankshaft position sensor temporarily. All connected vehicle damages to crankshaft position sensors can only be fixed by replacement.|
Advantages of changing a crankshaft position sensor.
Any defective component that is changed for a better, well-functioning one improves the entire machine. The benefits of changing a vehicle’s crankshaft position sensor include the following.
|Advantages of changing a crankshaft position sensor||Reason|
|An improvement in engine performance||The engine performs as it should once the crankshaft position sensor is replaced. Compared to the issues that were present before, the engine runs better.|
|No Overheating Problem||The temperature would be perfect, and there wouldn't be any overheating.|
|Consistent Driving||While driving, the engine won't jerk or suddenly stop. While the vehicle is moving, there should be no cut-offs.|
|Correct Readings||The engine will receive accurate timing from the replaced crankshaft position sensor, which will also improve other engine performances such as fuel injection and ignition.|
|Average Fuel Consumption||Once the malfunctioning crankshaft position sensor has been replaced, the increased fuel consumption brought on by it will revert to normal.|
What Happens if a Crank Sensor Is Unplugged?
When you detach your vehicle’s crank sensor, a lot of things can happen. Following the crank sensor’s disconnection, you can encounter certain symptoms.
An stalled engine.
Your automobile will take longer to accelerate and, in rare situations, may even stop altogether. Once the crankshaft sensor is disconnected, it will no longer be able to transmit information on the state of the crankshaft. Your engine may be purposefully stalled by the PCM in order to protect it from damage.
Surprise Engine Turn off.
Only the detached sensor can cause your engine to stop abruptly. The PCM may alter the fuel timing so that the engine receives less gasoline and shuts off as a result.
The “Check Engine” light.
Once you detach the crankshaft sensor, your engine light will turn on. The engine is merely alerting you to the fact that it can no longer monitor the crankshaft due to a break in communication with the sensors.
You can find it difficult to start your engine following the disconnect, which is another sign.
The crankshaft is essential to the vehicle’s operation. The PCM can no longer communicate with the crankshaft, which makes starting the engine more difficult. Your car might occasionally not even turn on.
Engine vibration or misfires
After you detach the crankshaft sensor, your engine is likely to misfire. It’s because the sensor won’t be able to give the PCM the data it needs to know about the piston’s position. Thus, the PCM is unable to control certain engine components.
How Can I Tell If My Crankshaft Position Sensor Is Bad?
- You can check the location of your crankshaft in two key methods. Either a multimeter or a scanner are options.
- The first technique makes use of a multimeter tool, which is more prevalent than a scanner. It gauges the voltage of the vehicle’s electrical parts or components.
- After getting the multimeter, you can proceed to disconnect the CKP sensor, which is a rather simple process. To find the sensor, go to the owner’s manual for your car. When unplugging a sensor, connect one end of the multimeter to the wiring of the sensor.
- The sensor is not functioning if the multimeter displays resistance of zero or infinite resistance. A reading of 0 resistance indicates a short circuit, while an infinite reading indicates an open circuit.
- The second technique entails checking the voltage output as the engine is started. To complete this, you can enlist the assistance of a friend. With the engine’s moving parts, you must exercise caution.
- Start the engine after connecting the multimeter to the sensor wiring. Around 200 millivolts should appear on the readout. Although the measurement may vary between vehicles, you can find your particular measurement in the vehicle’s manual.
- Your car’s computer can quickly check for crankshaft position sensor-related faults using a scanning tool. As soon as the codes are verified, the sensor needs to be changed right away.

Does Battery Disconnection Reset the Crankshaft Sensor?
Resetting the crankshaft sensor on your car requires disconnecting the battery. The power in all the electronic parts of your car, including the crankshaft sensor and PCM, will be exhausted if the battery is removed for a while. By doing this, the system will be reset and any short-term memories will be cleared.
The failing crankshaft sensor problem will not be resolved by resetting the system; the sensor must be replaced instead. So don’t think of this as a solution to your issue.
Cost of changing the crankshaft sensor.
To safeguard the engine and make the vehicle run more smoothly and safely, it would be beneficial if you replaced the poor crankshaft sensor.
Today, a crank sensor might cost anywhere between $75 and $120, depending on the car. A CKP sensor replacement costs between $120 and $300 when labor is factored in.
Will Driving a Car with a Faulty Sensor Cause Car Damage?
Driving your car when the CKP sensor is broken might seriously harm your engine system. Your engine’s inability to run without the sensor is demonstrated when it begins to shake excessively and uncontrollably, shuts off unexpectedly, and misfires. It would be better if you had the car checked out right away by an experienced mechanic.
When your engine begins to shake excessively, other engine components may begin to move out of place. If you continue to drive in this situation, the engine could fail and the car could sustain additional damage.
Often Asked Questions on crankshaft position sensor
Q) Without a crankshaft position sensor, can a car be driven?
