How to Install a Camshaft Position Sensor How to Install a Camshaft Position Sensor
A camshaft position sensor is often situated near or around the crankshaft. This small component is an important part in the engine largely because it sends information to the on-board computer that is used to determine the speed and position of the crankshaft. This, in turn, sends the necessary data to make adjustments that will increase or decrease the speed of the vehicle until the engine has reached its optimum level of performance.
Step 1 - Locating the Camshaft Position Sensor
Before you can actually install a camshaft position sensor, you first need to know where to find it. Fortunately, the camshaft position sensor can easily be located. Generally, the sensor is located directly or near the area of the crankshaft. It is often situated near the top of the engine casing. The casing should be near the intake or exhaust camshaft.
Since the camshaft position sensor is easily accessible without having to remove other parts of the engine, installing one will not be that difficult.
Step 2 - Removing the Bolts and Plugs
Once you have located the camshaft position sensor, you can now start to remove it. The sensor has small bolts that hold it in place. The sensor is also connected to the fuel injection system via a plug that has 2 wires.
With the socket or adjustable wrench, remove the bolts that hold the camshaft position sensor in place. Make sure that you do not misplace these bolts since you would need it to bolt the new one. After removing the bolts, remove the plugs that connect it the fuel injection system. You can now remove the sensor from the casing.
Step 3 - Testing the Camshaft Position Sensor
Before you install the camshaft position sensor, make sure it works properly. To check, connect the sensor to a multimeter and set it to the diode test function or a low resistance setting. You then need to pass a magnet in front of the sensor. Make sure you do this several times to be sure. The reading should make significant changes to determine that the sensor is working properly.
Step 4 - Locating the Cylinder Head
Once tested, you can now start installing the sensor. Locate the cylinder head. This is where you will install the camshaft position sensor.
Step 5 - Installing the "O" Ring
You then need to place a new "O" ring on the camshaft position sensor. It is important that you lightly coat the ring with engine oil. Once you have oiled it, place it on the cylinder head and tighten the bolts.
Step 6 - Placing the Camshaft Position Sensor
You can now attach the sensor to the electrical connector. The connector should lock in place when you plug it in. To remove it, just press the release tab.
Step 7 - Re-install the Bolts
After placing the sensor, connect it to the fuel injection system again. Bolt the camshaft position sensor and then put the engine casing back.
