How To Temporary Fix For Crankshaft Position Sensor? If your car is displaying any of the following symptoms, it may have a problem with its crankshaft position sensor: the engine stalls, starts and stalls, or has a hard time starting.

These issues can be caused by a number of things, but a faulty crankshaft position sensor is one possibility. If you suspect your sensor is the problem, there is a temporary fix you can try before taking your car to a mechanic.

How Does The Crankshaft Position Sensor Work?

The crankshaft in an internal combustion engine is the part that converts reciprocating motion from the piston into the rotation of the wheel shaft. This allows the wheel to rotate in any direction it desires.

But, an essential component of the crankshaft is often overlooked. It is the crankshaft position sensor (CKP)

The CKP sensor checks the crankshaft’s speed and transmits it to the Engine Control Unit (ECU).

The crank sensor provides data to the ECU, which adjusts the fuel burn time, refueling time and exhaust time. The ECU can adjust the engine’s energy and make the vehicle move at the right speed.

The crankshaft sensor, in short, is an essential sensor for an internal combustion engine. The engine control unit can’t know the exact speed and position of the crankshaft without the CKP sensor.

A malfunctioning crankshaft position sensor can also cause your vehicle and engine to run inefficiently or stably. These 6 symptoms are indicators that your crank sensor is not working properly.

What causes crankshaft sensor damage?

What causes crankshaft sensor damage?

It is essential to diagnose any problems with your crankshaft position sensor immediately.

There are many reasons why your engine might fail. It is essential to have it checked by a mechanic. Wearing or damaged parts, water intrusion, and poor connections are common causes.

You can check the codes for possible signs that your crankshaft position sensor may be the problem. If you get check engine light codes, your sensor may be the problem.

1. Overheating Engine

Your engine may be overheating if you are experiencing crankshaft position sensor issues. You can have this problem due to a blocked engine air filter.

Flawed fuel injection system, ter, or a faulty thermostat. You can prevent crankshaft position sensor problems in the future by making sure you check all possible causes of engine overheating. Then, take the necessary steps to correct the problem. If you hear unusual vibrations or noises, it is a good idea to have your engine checked out by a professional.

2. Faulty Voltage and Damaged Wire

A problem with the crankshaft position sensor could cause a decrease in engine performance and loss of power. This sensor sends signals to the engine control module (ECM) to determine the crankshaft position.

Let’s say that the wire connecting to the ECM has been damaged. The sensor will then send a faulty voltage, which eventually causes it to fail. You will need to take your vehicle to a mechanic to fix the problem. It may be necessary to replace the wire or the entire sensor, depending on the extent of the damage. To avoid unexpected problems down the line, it is always a good idea for your car to be inspected by a mechanic.

6 Signs That Your Crankshaft Position Sensor Has A Problem?

1. Check engine light

The engine won’t work correctly if the engine control unit doesn’t receive speed and crankshaft position information. The “check engine” indicator will illuminate your car’s dashboard if the crankshaft position sensor is not working correctly. This could be the first sign the CKP sensor has problems.

A bright “check engine light” can be caused by crank sensor malfunction or other reasons. The “check engine light flashing” and “car shaking” can be described as a crank sensor malfunction. You can also use the OBD-II to identify the problem.

2. Strong shaking of engine and vehicle

It vibrates or jerks occasionally when the vehicle is in motion. It is also difficult to accelerate. A problem in the CKP sensor could cause this.

This is often caused by a miscommunication between ECU and crankshaft, which causes the engine not to get enough fuel. This problem can cause severe engine damage if it isn’t fixed immediately.

3. Engine suddenly stops

A bad crankshaft position sensor can also cause your engine to stop running suddenly and your car to stop in the middle. The ECU adjusts the fueling time to ensure the engine doesn’t get enough fuel. This sudden engine shutdown will occur more often if the CKP sensor is not repaired in time.

4. It isn’t easy to accelerate suddenly.

The ECU will not operate the engine correctly if there is a problem with the crankshaft position sensor. This will cause you to feel uncomfortable as the car doesn’t have enough energy for you to accelerate as fast as you like.

5. Impossible to get the car started

Starting the car becomes more complicated if there are problems with the engine, ECU or CKP sensor. It is essential to fix the problems quickly, as the chances of it starting are lower the more extended the engine takes.

6. Mistake

When the CKP sensor does not provide information about the crankshaft speed and piston position, the ECU will misfire. Misfiring can also be an indirect cause of engine vibration or shutdown.

How to temporary fix for crankshaft position sensor?

How to temporary fix for crankshaft position sensor?

Your crankshaft position sensor may be faulty if your car displays at least two of the six signs. It is important to bring your vehicle quickly to the shop for repair and inspection.

If you cannot go to an auto repair shop, these temporary solutions will work. These are especially useful in cases of sudden car stops.

1. Start the engine again

Pull over to the curb if your car shakes or jerks while driving. You can reduce shock by stopping the car, turning off the engine and waiting for it to cool down before starting the machine again.

2. Fuel tank filling

You can fill up the ECU with fuel if the car stops suddenly.

3. Disconnect CKP sensor

Try disabling the crank sensor if your car is having trouble starting.

First, locate the CKP sensor as per the instructions (near the camshaft).

Next, remove the CKP connector and start the car. If the car is lucky, it will use the default mapping.

If the car does not start after a few attempts, it is worth replacing the CKP sensor.

How to Replace the Crankshaft Position Sensor?

It is only one bolt or screw that secures the crankshaft position sensor. This makes it easy to change. To remove the old sensor, disconnect the power plug from the bolt and pull it out.

Finding the sensor is the most challenging part of the job since it can be located deep within the engine bay. Each vehicle is different, but the sensor is generally located in the area between the engine and the transmission, near the flywheel.

How Do You Test a Crankshaft Position Sensor?

A test lamp is required to test the crankshaft position sensor. There are two types of crankshaft sensors: one for 2-wire and one for 3-wire. Each model has a different testing process.

1. How do you test the 2-wire crankshaft position sensor?

Disconnect the crankshaft position sensor.

Connect the test lamp and the positive battery terminal.

Move the ignition to “On”.

Tap the sensor terminals quickly and repeatedly.

The sensor is working if you can hear the spark plug clicking when you do this.

2. How do you test the 3-wire crankshaft position sensor?

Disconnect the crankshaft position sensor.

Connect the test lamp and ground battery terminal.

Move the ignition to “On”.

Tap the middle to activate the signal terminal

The sensor is working if you can hear the spark plug clicking when you do this.

These tests check the vehicle’s response to the sensor signal. These tests are accompanied by an injector pulse and a spark plug click.

If you have a 2-wire sensor, attach the test lamp to the positive terminal. Please attach it to the negative terminal for a 3-wire sensor.

How Do You Test a Crankshaft Position Sensor?


1. Can a crankshaft sensor be bypassed?

The crankshaft sensor can’t be bypassed in any circumstance. The ECU won’t know when to trigger ignition or injection without it. Therefore, the engine won’t be able to start.

Even if the engine is starting, it won’t run smoothly. It will stall and misfire. If you want to maintain the engine in top condition, don’t try to bypass the crankshaft sensor.

2. Can you reset a crankshaft position sensor?

Yes, it is possible to reset the sensor to re-learn the crankshaft and calibrate with it. It is usually done with a new sensor but can also be used to help an older sensor work again.

3. Is there a difference between the crankshaft sensor and the camshaft sensor?

The two sensors have a fundamental difference. Although they share the same operating principle, they capture the location of the part and send it to the ECU. The names indicate that they cover different parts.

Camshaft position sensors are responsible for opening and closing the valves.

The crankshaft sensor monitors and controls the crankshaft. This turns the linear power from the pistons into rotational force, which powers the vehicle, the serpentine belt, and the timing belt.

4. How do I fix the error code p0340?

The failure crankshaft position sensor is the reason for the p0340 code. You will need to replace the sensor, reset the ECU, or clear the error code using an OBD2 scanner.

5. Can a broken crankshaft be repaired?

It is not a good idea to repair the crankshaft. Instead, it is better to replace it with a new one.

6. Is it difficult to replace a crankshaft?

The most difficult task on a car is to replace the crankshaft. To access the crankshaft, the process begins underneath the car. First, the oil must be drained. Next, the drain pan must be removed.

Next, remove the pistons from the crankshaft. Also, take off the front portion that connects to the serpentine belt pulley and the back portion to the transmission.

Only then can you remove the crankshaft. However, re-installing it requires experience and precision that a professional mechanic does not have. It is best to leave the job to professionals if you have to replace the crankshaft.

7. What is the average time it takes to repair a crankshaft pulley?

A professional can remove the crankshaft pulley and re-install it in under two hours. Depending on the extent of disassembly, it will take a DIY mechanic 3-4 hours.

8. Can you drive a car with a crankshaft sensor but no crankshaft sensor?

The crankshaft position sensor (CKP) is essential for operating a vehicle. The CKP sensor is essential for running a car.

9. What happens if my crankshaft position sensor is defective?

A defective crankshaft position sensor won’t transmit exact crankshaft location and rotational speed information (ECU) to the engine control unit.

The ECU can’t regulate the engine’s fuel intake, combustion, or exhaust time accurately. If the CKP sensor is defective, driving may cause the vehicle to jerk, shake vigorously, shut off suddenly and not accelerate as it should.

Last words

You now know what temporary fixes you can use to fix your crankshaft position sensor. You will see that most temporary fixes involve either cooling the engine or fuelling up.

In cases like wiring problems, where the situation is too hazardous to repair temporarily, it’s better to get a permanent solution, not just a temporary fix.

It is much better to hire a professional car mechanic to handle this job than to try to fix it yourself. Any temporary fix’s goal is to ensure you are safe permanently.
