How To Change A Crankshaft Position Sensor

There’s no need to be a mechanic to change your crankshaft position sensor. In fact, changing this sensor is one of the most common service procedures that you can do on your own car. This article will teach you how to change your crankshaft position sensor without any difficulty, and it will also provide you with some helpful tips on how to keep your car running smoothly. So don’t wait—start changing your own parts today!

What is a Crankshaft Position Sensor?

A crankshaft position sensor is a sensitive device that measures the distance between the crankshaft and the top of the piston stroke. This information is used by the engine control unit to optimize engine performance. When there is a problem with the sensor, it can result in poor fuel economy or even engine failure. The best way to diagnose and fix a crankshaft position sensor issue is to replace it.

How to Change a Crankshaft Position Sensor on a Toyota Camry

If your Toyota Camry is experiencing engine misfire or poor fuel economy, it may be due to a faulty crankshaft position sensor. This article will show you how to change the sensor on a Toyota Camry.

1. Locate the crankshaft position sensor on the engine block near the oil pan. The sensor is concealed beneath a metal bracket and can be accessed through a small opening in the bracket.

2. Remove the old crankshaft position sensor by gently prying it off of its mounting bracket with a thin flathead screwdriver. Be careful not to damage the wiring connector that attaches the sensor to the engine block!

3. Install the new crankshaft position sensor by lining it up with its mounting bracket and pressing it firmly into place using a thin screwdriver or your fingers. Make sure that the wiring connector is aligned properly and that there are no gaps around the edges of the sensor.

4. Reinstall any hardware that was removed during step 2, including the metal bracket and screwdriver attachment point. Once everything is reinstalled, re-lubricate all moving parts with motor oil or synthetic grease, and reattach any electrical connectors if necessary.

Tips for Changing a Crankshaft Position Sensor

If your car’s engine is giving you trouble, it may be because of a faulty crankshaft position sensor. This component tells the car’s computer how far the crankshaft has moved, and can therefore affect performance and fuel economy.

Here are four tips for changing a crankshaft position sensor:

1. Locate the sensor. The sensor is usually located near the crankcase on the engine block near the camshafts. If you have trouble finding it, try turning the engine over by hand while looking for a CLICK or TICKING sound from the engine as the sensors move.

2. Remove the sensor. Refer to your car’s service manual to find instructions on how to remove and replace this component. On most cars, you’ll need to remove several bolts and do some prying before getting it out. Make sure to label and save all of your components so that you can put them back together correctly!

3. Clean and lubricate the sensor bracket and pins. Once you’ve removed the sensor, use a clean cloth or paper towel to wipe off any debris or oil that may have accumulated on it during operation. Apply a light coat of petroleum jelly or other appropriate lubricant to both surfaces, then replace the bracket and pins in their original positions. Torque them to spec once everything is reinstalled (usually 12-14 ft-lbs).

4. Reinstall the engine cover and torque its bolts

How to Check if the Crankshaft Position Sensor is Working Correctly

If your car is having trouble starting or running poorly, it’s a good idea to check the engine sensor. The crankshaft position sensor (CPS) tells the engine computer how far the piston is from the bottom of the cylinder and this information is used to adjust fuel mixture and ignition timing. If the sensor isn’t working correctly, it can cause these problems.

To test if your CPS is working correctly, you’ll need to remove the intake manifold. First disconnect the battery negative cable and then remove the four cap screws that hold on the intake manifold cover. Next, carefully remove the cover.

Once you have access to the CPS, use a voltmeter to check for voltage at each lead. If there’s no voltage at any of the leads, it means that your CPS has failed. You can also try replacing the sensor, but if that doesn’t work, your car may require extensive repairwork.


Changing a crankshaft position sensor can be a tricky job, but with the right tools and advice, it should not be too difficult. If you’re feeling confident that you can tackle the task, read on for some tips on how to do it. Remember to use caution and take your time when working with machinery – if something goes wrong, it could be costly both in terms of money and time. Thanks for reading!
