Replacing a Camshaft Sensor

Replacing a camshaft sensor is a relatively easy job to do if you know what you’re doing and have the right tools. The camshaft sensor is a vital component to the engine, detecting when the spark plugs should fire in order to ensure the engine runs at maximum efficiency. With the wrong information or firing at the wrong time, the engine will struggle and misfire.

The first step to take when you need to replace your camshaft sensor is to remove the cable from the negative terminal of the car battery to prevent any electrical surge that could damage the control module or any electric shock to you if an accident occurs. Then, take out the service manual for your vehicle to locate the camshaft sensor in the engine compartment.

Once you have located the camshaft sensor, you will find that three small wires are connected to it – the sensor output, the feed, and the ground. Unclip these wires and mark each one before discarding the old camshaft sensor. Depending on where the camshaft sensor is, it can be held in with either screws or a bolt. If a rubber O-ring was between the camshaft sensor and the engine’s wall, a new one will need to be used with the replacement camshaft sensor.

With the new camshaft sensor in place, reattach all three wires to the sensor, making sure they are connected and positioned correctly. Once this is done, you can put the negative terminal back on the car battery and tighten it down. Turn the engine on to check and make sure the camshaft sensor is working correctly.

Replacing a camshaft sensor isn’t difficult or expensive and should be completed by any car enthusiast, even those who have little or no experience with motors. It not only ensures your engine runs with the optimal performance and reduces the risk of any motor damage, but it also eliminates the risk of electrical shocks if the job is done correctly.
