Have you ever wondered what would happen if your cam phaser went bad? The answer is not pretty. Cam phasers are the part of a car that controls when the valves open and close to allow fuel into the engine, which in turn allows for combustion.
When they go bad, it can cause all sorts of different problems, including but not limited to: poor gas mileage, high emissions levels, check engine light issues, and even complete engine failure.
This article will explore what happens when cam phasers go bad – time to replace with a new one!
So, with no further ado, let’s dive right in to see what is going on with your engine.

What Happens When Cam Phasers Go Bad?
The phasers on your vehicle’s engine give it numerous power. When this part goes bad, you will have some fix-required issues!
- Variable Cam Timing suffers damage.
- Turn on the systems’ warm-up mode.
- This results in phaser rattling.
- Lowers fuel efficiency
- Raises gasoline emissions
- Endangers the vehicle’s engine
- Cut down the engine’s max performance.
These signs indicate what will happen if your Cam phasers fail. Now that you know what’s going on let’s get into it!
The Variable Cam Timing Systems will be affected
VCT is a more sophisticated variant of typical cam-and-valve timing systems. By adjusting the camshaft-phasers, the valves can now open at different times. VCT can also be found on intake and exhaust cams.
The camshaft timing may be advanced or retarded by this mechanism, assisted by the powertrain control module. When phasers fail, they cannot manage valve timing. As a result, VCT systems fail.
Heat the system
We need to worry about one thing to keep the VCT system from suffering: getting it heated. The remote cam phasers heat our engine’s systems by damaging the valve-timing control unit (TCU).
Heat will surely collect and ruin the VCT if this mechanical component is not adjusted.
Camshaft-phaser issues are not something you want to deal with. The knocking sounds indicate a lack of cam phaser cavity’s increasing oil pressure, which causes wear and tears over time, ultimately resulting in poor engine performance!
To prevent this issue at its peak stage or before it ever becomes apparent, then make sure to check your Electrical Control Unit (ECU).
More Fuel Consumption
Cam phasers are an important component of the VCT because they manage engine function by managing oil pressure.
As these parts deteriorate, they lose their ability to improve your vehicle’s economy and instead take you down less-than-desirable routes such as greater fuel usage or emissions due to weak solenoids not delivering signals into valves as expected, resulting in lower flow rates.
Emission’s VCT is an important component of the engine’s emissions control system. It operates by lowering harmful carbon dioxide and hydrocarbons, but because this valve was malfunctioning, it caused even more problems.
Affect The Interior Engine
VVT technology is used to adjust the independent valve timing. It can also collaborate with a computer to decrease engine wear, fuel emissions while improving overall vehicle performance.
If this critical component fails, you might expect engine damage due to disruption.
Reduced engine performance
The intake camshaft, which features VCT, is in charge of optimizing engine performance, which means it can optimize the amount of air that enters your car’s combustion chambers.
This component connects directly with the powertrain control module (PCM), which regulates timing in all four-cylinder banks, resulting in optimal piston synergy and increased torque generation!
When the phase cam breaks, you cannot expect the PCM to work effectively. At this moment, your engine will be kept running by the ECU ( at limp).
The blinking indicates that there may have been an issue with your car’s engine, which will lower its high horsepower and can also assist in illuminating the LED on top!
If one fails, the VVT engines in your car require a cam phaser replacement because the ECU can’t operate without it. It will eventually cause failure, which would make you bring out an expensive repair job for something as simple to replace!
What Can Cause Bad Cam Phasers?
The most common reason for broken cam phasers is improper weighting. When oil pressure isn’t sufficient, it can lead to low friction inside and damage the solenoids or metal on the outside surfaces, which causes them not to work properly in your engine’s operating system.
How Can You Know Cam Phasers Gone Bad?
Broken Cam phasers will cause deeper knocking noises, cylinder misfiring in low and extremely high RPMs level, and backfiring. They also tend to wear out very quickly.
Should You Get New Cam Phasers?
It is not enough to replace the component; you must also replace all of its followers with new ones for them to function correctly again. If this does not occur, there will be even more issues than previously!
Cam phasers are the part of a car engine that regulates valve timing and duration. So, what happens when cam phasers go bad? It can lead to an expensive repair or even complete failure of the engine.
Once you are clear about the rotting signs, you have a better chance replacing your cam phasers before they affect your car. Thank you for reading this article and we will see you soon!
