The phasers are hydraulically operated and computer-controlled. It is part of the VVT system, helping to adjust the camshaft position, so valve timing is perfected for optimal performance from the motor. The main job of a cam phaser is to adjust the positioning of the engine’s camshaft. It must remain in the right position with the crankshaft to ensure proper valve timing within the engine. These computer-controlled sprockets are mounted to the cam drive sprocket, thereby controlling the camshaft.Ĭam phasers are needed to change the camshaft position. The cam phaser is an integral part of the VVT system, helping to improve efficiency, increase fuel economy and reduce emissions. Today’s modern vehicles are equipped with variable valve timing systems.

To replace a cam phaser, expect to spend $750 to $2,500, unless you can do it yourself. When it is bad, the Check Engine Light might come on, you might notice reduced engine performance and there might be a rattling noise. The cam phaser is a part of the variable valve timing system. By repairing it, you can ensure that the phasers continue working as intended. With the best code scanner, you can find these ECU problems quickly. If a fault keeps the computer from doing its job, the phaser could fail. The ECU is responsible for controlling the cam phasers. However, today’s top oil manufacturers provide everything needed to keep the engine running smoothly. If you are worried about proper lubrication, you can always add friction modifiers for less wear. If there is too much friction, these valuable parts are going to fail prematurely, leading to trouble with the cam phaser. Motor oil also helps to lubricate the gears and sprockets. Don’t forget to change the oil filter at the same time to ensure the fluid remains fresh. If you are using synthetic oil, you won’t need to change it as frequently as you would conventional oil. That’s why you should always change the oil at appropriate intervals. All of these elements lead to a reduced oil flow, which affects the well-being of the cam phasers. Contaminated OilĪs the oil gets old, it becomes contaminated with sludge, dirt and debris. Otherwise, the cam phasers are going to respond more slowly and become damaged. With the right oil used, you also ensure proper pressure. The engine constantly runs at extreme temperatures, and the wrong viscosity can lead to a lot of wear. You must use the right oil viscosity for the engine to ensure proper friction and lubrication. Poor oil pressure can also lead to wear inside the phasers, since they are constructed from metal and require lubrication. You could be struggling with oil pressure in your vehicle because of the oil quality or a failing oil pump. When the pressure is lacking, the cam phaser will go bad. The right amount of oil pressure is needed to provide power to each cam phaser. READ MORE: 7 Engine Noises You Should Not Ignore (& What They Mean) What Causes the Cam Phaser to Fail? 1. It’s easier to hear when the engine is idling or after it has been warmed up. You should hear it coming from the top of the motor. What happens as a result is a knocking or rattling sound. However, if the phaser has failed, it might not be capable of locking in place. The cam phaser should lock in position when the engine is at its base idle. You might notice trouble accelerating, a rough idle or trouble getting all of the power it normally exhibits.

With either of these problems, the engine is going to exhibit performance issues as a result. If the cam phaser isn’t operating correctly, the timing is going to be retarded or advanced.

The valve timing must be optimized to ensure the engine runs as it was intended. By reading the diagnostic trouble codes with your professional scanner, you should be able to narrow down the problem better. While this positioning problem could be the result of something else, it’s commonly an issue with the cam phaser. If the module gets a poor reading from the sensors, it’s going to turn on the Check Engine Light. With the help of the powertrain control module (PCM), the camshaft positioning is always monitored through sensors. The car computer lets you know whenever something is wrong with the system. Here is a more detailed list of the signs of a bad or failing cam phaser to look for: 1. You may also notice that the engine is noisier than usual, indicating that you need to inspect and fix it immediately. The most common symptoms of a bad cam phaser are lower engine performance and a check engine light on your dashboard.
